The advantages of UV LED pipe lining

When you need to line or repair a buried pipeline, whether it is gravity-fed or driven by pressure, there is often no need to dig up the pipe and suffer all of the cost and inconvenience of excavating a trench.

Trenchless pipeline installation and trenchless repairs are made possible thanks to ultraviolet light emitting diode (UV LED) pipe patches and liners.

Instead of digging up the ground, laying a lined pipe and then burying it again, directional drilling is used to bore a hole under the surface without disturbing the top layer of earth.

This is an ideal solution where there is above-ground infrastructure that cannot be disturbed or which would be difficult or expensive to reinstate after the work is complete.

But it’s also a convenient and cost-effective way to carry out all kinds of pipeline installations, from water pipes and sewers to utility pipes, without excavation costs.

And it’s all made possible thanks to innovative UV LED pipe lining and cured-in-place pipes, known as CIPP for short.

How does CIPP work?

CIPP is possible because of UV LED pipe lining technology. Instead of lining the pipe before it is put in place, the pipe can be inserted below ground first, before it is sealed against any minor leaks.

After the pipeline is complete, a liquid resin is injected into the interior, coating the inner walls of the pipe.

The resin is applied very quickly with good control over where it is deposited inside the pipe, making CIPP a process that offers excellent efficiency and relatively easy management.

Once the interior of the pipe is coated in liquid resin, UV LED light is used to activate the curing process. Again, this gives excellent control over curing, making CIPP resin very easy to work with.

CIPP can be used to patch leaking pipes once the location of the leak is known, or it can be used to line new pipelines that have only just been laid.

It can even be used as part of an auger boring process to upsize existing sewers and other pipes to handle greater capacity, again with all the advantages of trenchless technology.


At hebs Group we use cutting edge technology for both, including Pipe Aid LED Patches for straight pipe repair and Sewertronics SpeedyLight+ UV LED Curing Technology for new pipe installations.

Building maintenance after the winter period

The new year is not the end of winter – in fact it’s barely the start, as the season begins on December 22nd and lasts through until March 20th.

That means unfortunately, there is likely to be heavy weather on the horizon, which traditionally lasts throughout much of the rainy spring season too.

Despite the relatively calm and warm Christmas period, you shouldn’t be complacent about building maintenance during winter and into spring.

1. Building maintenance priorities in winter

Precipitation in all its forms is a threat during the winter months, so make sure your building fabric is robust against heavy rainfall.

That means ensuring your roof does not leak and that drainage is working correctly, including roof-edge guttering and drainpipes.

If you notice specific sections of your guttering overflow during heavy rain, get them looked at to find out if a joint has sagged, if your guttering is blocked, or if you just need more drainpipes installing.

We haven’t had heavy snow this winter but it’s still worth getting old roofs surveyed to make sure they will take the weight of future snowfall – it can be very costly to reinstate a collapsed roof compared with reinforcing an existing one.

2. Building maintenance priorities after winter

As we move towards March and the official start of spring, give some thought to any work you want to carry out during the summer months.

In theory, late spring and early summer should bring more stable weather conditions, but they’re also a very busy time for building maintenance contractors.

So anything you can do to plan further ahead can help you to schedule the work and get it booked in well ahead of time.

Again, if you’re considering roof work, the spring-summer season can be a good time for this as dry days are ideal for work that disrupts the waterproofing on your roof.

3. Building maintenance after heavy weather

At any time, the weather could take a turn for the worse. Instead of seeing this as a threat, think of it as an opportunity to identify problems with your building fabric.

Make a note of the locations of any leaks so you can get a building surveyor to come and diagnose them, as well as any unusually draughty areas where you want to reseal your exterior to keep out strong winds.

It can be difficult to stay aware of small and isolated problems on very large buildings, especially high buildings where you might not routinely see the roof.

But it’s essential to keep the weather on the outside of your premises – so if in doubt, book a roof survey or a full survey of your exterior building fabric to decide if more work needs to be done.

Construction Industry Trends for 2020

As we leave 2019 behind and enter a new decade, it’s time to investigate the latest construction industry trends for 2020.

At hebs group, we believe in keeping up with new and emerging trends as part of our growth and prepare for the future in an industry that continues to evolve year on year.

There are so many advancements and we intend to make our new build, fit out, and refurbishment projects easier, safer, and more efficient for clients.


One of the biggest focuses in building construction and design is sustainability. Over the years, companies have aimed to reduce their carbon emissions and use resources effectively at a fraction of the cost.

Such solutions include better thermal materials like sheep’s wool insulation designed to last and keep buildings protected and heated for longer.

Effective water usage to help maintain reservoir levels, and maximising natural lighting in building design to reduce electrical costs are just some of the ways in which we can build a sustainable future.

Green construction

Similar to sustainability, green construction refers to incorporating environmentally friendly methods and products in each step of a project; from the planning stages right through to construction, maintenance and demolition.

A green building is an economically efficient one, and means less damage to the environment, especially with regards to the high level of derelict buildings.

Some materials like timber for formwork, bamboo as an alternative to concrete construction and using recycled plastics instead of sourcing new materials are becoming increasingly popular. According to a Statista report, the green building materials market will reach 433 billion U.S. dollars by 2024.

VR and Robotics

If you thought VR and robotics is made for the media, gamers, and techno enthusiasts – think again!

These technologies are already making a big impact in the construction industry by helping designers and architectures to visualise buildings in detail and spot errors quickly.

Drones are on the rise too and according to ABI research the collaborative robotics market is predicted to surge to $1 billion in total revenue by 2020. These could be a huge advantage on construction sites for surveying and ensuring the safety of workers.

Keeping your office space fresh for Christmas

As we move through Christmas and New Year into the true winter months, it’s the time of year when a tired old office space really starts to show the cracks – sometimes literally.

But well-kept premises can keep employees comfortable and productive when the weather is raging outside.

Here are five hebs Group services that can help keep office space fresh this Christmas and well into next year and beyond.

Commercial Fit-Out

Newly built premises can benefit from hebs Group’s expertise in commercial fit-out projects, to create an office interior conducive to work and fit for all seasons.

Your initial fit-out is a significant investment and one you will want to last for as long as possible, whether your exterior is newly constructed or an existing building that has been converted.

We can help to make best use of the space available and complete your commercial fit-out on time so there are no delays to your business moving into its new home.


If you have existing premises but they feel tired, stale or cold and draughty, hebs Group can help with our refurbishment service.

We offer the full range of expertise required to bring your office interiors up to standard and can advise on installing building controls to make more efficient use of energy too.

Building Fabric

The exterior fabric of your building is as important as the interior, and perhaps even more so.

If you’re investing on interior refurbishment, make sure you get the exterior building fabric of your offices brought up to date.

As well as sealing any draughts and insulating against costly energy leaks, this can give your building a fresh new look, enhancing its kerb appeal to prospective clients and talented job applicants.


Don’t fall victim to a weak or leaky roof that collapses under the weight of winter snowfall or lets in torrential rain.

Roof problems can cascade quite literally down through the building, causing expensive repairs at every level.

At hebs Group we have a proven track record installing secondary roofs such as cut to fall overlays, giving you a reliable roof with minimal disruption.


Don’t ignore your air conditioning just because it’s winter. Office air conditioning systems handle much more than just cooling the air in summer.

A well-maintained HVAC system filters and circulates clean air, preventing offices from feeling stale and stuffy.

This fresh feeling comes with cost benefits too, as circulated warm air from air conditioning systems is a highly efficient way to warm up a cold open-plan office space.



Water efficiency – How hebs Group can reduce water wastage

We live on a pretty wet island so you’d think we’d have more than enough water, but water efficiency is always worth investing in.

The clean water we drink and bathe in doesn’t come from nowhere – we have to collect it, clean it and deliver it to the point of use – so resource efficiency helps to reduce costs, carbon footprints and ensure there’s always enough to go around.

At hebs Group we believe strongly in maximising water efficiency. Recently, we were proud to deliver a project to replace 750 pod bathrooms and measure how much water was saved as a result.

How to improve water efficiency

For this recent project, hebs Group were asked to replace the internal fixtures of pod bathrooms across three different sites, with 750 to do in total.

We had three weeks to deliver this – that’s about 50 bathrooms a day!

Water efficiency was a requirement of the project, so we added flow regulation valves to the pipework to reduce water flow to the sink, and new basin aerators.

Once the work was done, we were able to measure the amount of water at the outlet and report back to the client in terms of gallons of water saved across the project as a whole.

They were so happy with the result that they have decided to roll out the changes across their estates, with a huge quantity of water to be saved overall.

Why is water efficiency important?

Water efficiency matters on a number of levels.

On metered connections, it saves on cost. In premises with many pod or en suite bathrooms, it helps to maintain water pressure at peak times.

It’s better for the environment too – not only consuming less from the mains supply so less water needs to be cleaned and delivered, but also preserving reservoir levels for longer during droughts.

There are similar benefits if you’re off the mains water grid too, by reducing the amount of water you have to treat via chlorination and similar processes.

Find out more

If you’d like to know more about how hebs Group can help you improve water efficiency across your estate – with measurable, monitored and reported results – contact us today.

You can call us on 0151 236 0707 with any questions or to learn more about case studies like the one above.

We’re always happy to talk through our past successes and to decide how we can help you to achieve your aims, whether they relate to water efficiency or another resource such as energy efficiency and renewables.

Refurbishing your restaurant or diner for the upcoming winter season

Winter is a crucial season for restaurants, diners and other foodservice establishments, especially during the Christmas rush, and hebs Group are anticipating a high number of restaurant refurbishment projects over the autumn-winter season this year.

A high-quality restaurant refurbishment can quickly cover its own costs in increased bookings, especially for large Christmas parties whether for businesses, families or groups of friends celebrating the season together.

It’s important to recognise that restaurant and diner refurbishments can be as extensive or as limited as you’d like – working within the existing configuration of the premises with internal walls, built-in booths and so on, or ripping out the internal footprint to start from scratch.

At hebs Group we have the expertise to handle these different levels of project, whether you need full structurally sound reconstruction of internal walls, or something that goes little further than surface redecoration.

In and out

We know time is of the essence, especially in the run-up to Christmas when you don’t want any avoidable downtime, which is why our team will be in and out as quickly and seamlessly as possible, leaving you with no clean-up to carry out.

Our fast track approach to foodservice refurbishment means we can complete large projects within a matter of weeks, even where there is considerable structural work to carry out like relocating the position of the servery and other core elements of your kitchen and dining area.

Everything is completed with the express aim of getting you back in business quickly, while ensuring your diners won’t be confronted with unwelcome aromas like fresh paint and other evidence of the recent building work carried out.

We work with you

We are happy to work closely with your own operations team to make sure the work we do fits with your schedule and short-term goals.

If you would like to see examples of our past projects, we have plenty of restaurant refurbishment case studies available, from surface finishes, to complete turnkey refurbs with complex demands.

We also work on dining areas in multi-use establishments – for example, cafe areas in gyms and fitness centres, restaurant areas in hotels, and so on – so if your refurb is one part of larger premises, we can deliver with a minimum of disruption.


To find out more, please contact us today. You can call hebs Group on 0151 236 0707 or email and a member of our team will reply to your enquiry as soon as possible.

How to keep your roof maintenance under control during autumn/winter weather

The autumn and winter months pose a growing challenge to commercial roof maintenance, both over the course of each year, and as weather patterns become more extreme in the longer term.

As the wetter weather of autumn sets in, roofs face their first test as any leaks that have gone unnoticed over the summer months are much more likely to become apparent.

Drainage is also an issue – including roof-edge guttering and drainpipes clogged by fallen leaves and other debris from the late summer.

Meanwhile as the winter weather arrives, there are even more complications, such as the risk of ice forming on roofs, heavy accumulations of snowfall, and freeze-thaw effects on pipes including drainage and water supplies alike.

All of this demands attention and with the risk of water damage when your roof leaks, it’s a case of the sooner the better.

The autumn of 2019 has already seen severe weather warnings and record-breaking hurricane activity heading eastwards over the Atlantic.

If you have any concerns at all about your roof fabric, or you simply haven’t carried out any routine roof maintenance recently, now is the time.

Solutions for weak or leaking roofs

Commercial roof repairs need to tick all the boxes, being fast, affordable, long-lasting and ideally causing the minimum of disruption to the premises.

For all of these purposes, a roof overlay system such as a cut to fall roof can be a good option, especially on roofs where the problems are caused by a lack of pitch.

Flat roofs naturally have less ability to disperse rainwater, as it does not naturally run off of a flat surface, especially if the roof has started to sag in places.

A cut to fall roof works by overlaying the existing roof with a watertight pitched layer, creating an angled top surface that controls rainwater run-off.

This can then be guided towards a particular gutter or drain, often laid along the centre of the roof rather than the edge, and the excess water is then drained away safely.

At hebs Group we can provide case studies of our past work in this area and have considerable expertise in ensuring roofs of all types are well maintained, waterproof and strong enough to withstand expected snowfall.

Together this helps to give you weatherproof premises for the coming autumn-winter season, allowing you to keep trading without any major and costly business interruptions whatever the weather.

We make it our priority to go the extra mile when it comes to building and facilities management, especially with hebs Flowtech – specialising in drainage and sewer maintenance for customers across the north, using innovative technologies and eco-friendly strategies for excellent results.

What is the future of green field installations for 5G telecommunications?

A newly launched competition is to give up to ten rural locations funding totalling £30 million to trial new 5G telecommunications installations that could have big implications for the future of green field installations for the telecoms sector.

The competition was launched in late August by digital secretary Nicky Morgan, with the aim to pioneer ‘testbeds’ for 5G phone masts in rural parts of the UK.

She said: “In modern Britain people expect to be connected wherever they are. And so we’re committed to securing widespread mobile coverage and must make sure we have the right planning laws to give the UK the best infrastructure to stay ahead.”

At the same time, the government launched a consultation on planning rules for new 5G phone masts, which could make it much easier for mobile network operators to install taller 5G masts on green field and rural sites.

The proposals could see much taller masts become a common feature in rural landscapes; however, the ultimate aim is to reduce the total number of masts needed to give the same coverage.

By allowing taller and bigger masts equipped with a larger amount of supporting technology in one place, coverage by each could be greater, allowing smaller, older and redundant masts to be removed.

Installing 5G telecommunications in rural locations 

Clearly there will always be public concerns about installing 5G telecommunications in rural locations, so it is important to do so sympathetically to the landscape.

At hebs Group we have a huge amount of experience in green field civils and electrical installations for the telecommunications sector, as more come online, we will apply this knowledge and expertise to 5G masts of all sizes too.

Under the current government proposals, this could include several changes to new and existing mobile infrastructure:

  • Fewer but taller masts including mast-sharing agreements.
  • Strengthening of existing masts to support 5G and mast sharing.
  • Installing radio equipment cabinets without prior approval needed.

This last proposal includes both unprotected and protected land, although it would not extend to SSSIs.

In urban areas and rural residential communities, the proposals would also allow 5G masts to be built nearer to roads and located on buildings to provide better coverage.

For all of these emerging opportunities in 5G telecoms mast installation and the civils and electrical infrastructure required for them in green field locations, hebs Group will work hard to support the roll-out of 5G infrastructure and the mobile networks who operate it.


The right time for trenchless repair

Trenchless repair of damaged pipes and sewers is one of the most demanded services available from hebs Flowtech, the specialist drainage contractor from hebs Group.

It’s a way to repair leaks, strengthen ageing pipelines and prepare for wet weather ahead – which is why the dry part of the year is the ideal time to enquire about trenchless repair.

We all know the British weather is changeable, but by acting when the sun shines, you can make sure your drainage, sewers and other pipelines are up to the task of carrying away excess rainwater once the clouds return.


Why get pipework repaired in summer?

Summer is not the only time of year for trenchless repair of damaged pipes, but it’s one of the best, thanks to the warmer temperatures and generally more settled conditions.

In fact these favorable conditions last right through from spring well into the autumn, depending on short-term weather patterns, and this is the peak period for trenchless repair work in a typical year.

During winter, sub-zero temperatures can make it more difficult to work with frozen soil, wet weather conditions can lead to expensive dewatering and difficult to Stabilise excavations when inserting slip trenches and receiving pits and of course it is more likely that your pipes and drains will already be filled with water, especially if they are in a poor state of repair.

That’s not to say that trenchless pipe repair in winter is out of the question either, but the warmer days, lower rainfall and longer hours of sunlight all make summer the ideal season to make a start.


Preparing for rainy days

If there’s one thing you can count on, it’s a return of rainy days at some point before too long, and usually longer spells of inclement weather as autumn progresses into winter.

Where you suffered leaks or structural weaknesses in drains, sewers and pipelines over the past winter, or if you suspect a leak may be forming, or even if you just want to be safe and not sorry, hebs Flowtech’s engineers can help.

Our state-of-the-art inspection equipment can check for damage along your pipes before any repair work is carried out, to ensure that the work is necessary and to determine the best solution given the specific circumstances.

You can read more about our trenchless solutions, including LED UV-cured patch repairs, both on our website and in our recent blog posts.

We also have further information about our general drainage and pipeline maintenance services, inspection, unblocking, descaling and repair – or just get in touch directly with any questions, and we will be happy to help.

All about Primus Line Kevlar liners for trenchless rehabilitation

At hebs Flowtech we are able to offer Primus Line Kevlar liners for trenchless rehabilitation of pressure pipes across a range of different industrial applications.

Primus Line Kevlar liners overcome some of the common problems faced with industrial pressure pipes, for example:

  • Weaknesses in bends and corners.
  • Loss of strength due to age and corrosion.
  • Sensitive installation environments.
  • Long length pipeline installations.
  • High hydraulic capacity demands.

This is all thanks to the Kevlar construction of the pipes, which strengthens the structure while allowing the walls of the pipe to be much thinner – and this in turn means the inner diameter of the pipe can be bigger, supporting higher capacity and flow rates.


Construction of Primus Line Kevlar liners

Primus Line Kevlar liners have three distinct layers that combine to create a flexible but incredibly strong cross-section:

  • An outer layer of abrasion-resistant polyurethane known as the sheath.
  • A load-bearing Kevlar layer (or double layer) of seamless woven aramid fibres.
  • A media-specific inner layer of polyurethane or thermoplastic polyurethane (TPU).

The single or double Kevlar layer hidden between the polyurethane layers gives the pipe its extremely high load-bearing strength, while allowing the total construction of the pipe walls to be much thinner than if solid high-density polyethylene or a similar material were to be used.

In turn, this maximises flow capacity but also means that these thinner pipe walls are more flexible, and Primus Line can negotiate around bends of up to 45 degrees, with a series of specially designed connectors to navigate around any even tighter corners as required.


Trenchless rehabilitation with Primus Line Kevlar liners

At hebs Flowtech we can install Primus Line Kevlar liners as part of trenchless rehabilitation work, which means less disruption, less delay and less cost to reinstate disturbed ground.

This again is due in part to the flexibility and strength of Primus Line, which can be inserted into the existing pipework in need of trenchless rehabilitation, but does not need to be bonded to the inner surface of the pipe.

Because of their excellent load-bearing strength, Primus Line liners are self-supporting and able to ‘float’ inside the existing pipe, while their thin walls mean only a minimal reduction in the inner diameter of the pipeline.

To find out more about this innovative solution for trenchless pipeline rehabilitation, ask hebs Flowtech about Primus Line Kevlar liners today on +44 0151 236 0707 or by email to
