Hadlee & Brunton offer trenchless pipe repair solutions to solve most issues that clients may have with pipelines and infrastructure assets. Whether the problem is isolated to a particular area or is consistent throughout a pipeline, we have the ability to assess and rectify the problem with our various trenchless solutions.
H&B are able to provide the full catalogue of Amex Sanivar’s pipe seals known as the “Amex Seals”. There are many different applications of the seals that can be used to repair broken or cracked pipes or displaced joints meaning the requirement for full pipeline replacement could be eliminated. There are options to custom make the seals to suit a specific pipe diameter or profile which can be designed and fabricated on a case-by-case basis.
Amex Seals are composed of EPDM rubber providing both flexibility and endurance

Hadlee & Brunton specialise in patching existing drainage pipes with a fibreglass repair. This is a cost effective and easy to use solution for the permanent and watertight repair of damaged pipes, without the need for excavation work. We can patch a damaged section of pipe over 40m from where we enter the drain. We can repair most types of pipes including ceramic / clay, concrete, uPVC, metal and much more, from 25mm up to 1200mm in diameter. The Fernco Pipe Doctor is installed internally and eradicates the need for costly, disruptive and time consuming excavation work therefore enabling both vehicle and pedestrian traffic to move freely without realising drainage and sewer work is being carried out underground.
Even in the presence of damp substrates, Ultracoat will effectively adhere to any surface, eliminating and preventing infiltration and leaving a smooth finish with enhanced flow characteristics. Application of Ultracoat is also structurally reinforcing – independent testing showed an increase in compressive strength of concrete pipes of 20%.
After application, for example for bund rehabilitation, the Ultracoat 100% solids epoxy coating system is chemical resistant from pH 2-14. This includes complete resistance to high levels of hydrogen sulphide, up to 40% concentration of nitric acid, acetic acid, calcium chloride and others.
Particularly relevant for manhole rehabilitation and other confined spaces, the Ultracoat system is free from VOCs (volatile organic compounds), meaning breathing apparatus is not required. It is free from solvents and no primer coat is required – application is quick and easy and a manhole chamber or culvert can be back in operation within hours of the project starting.
The Ultracoat epoxy coating system was developed by Danny Warren of Warren Environmental in the USA over 35 years ago and has been used to renovate over 50,000 manholes and kilometres of pipes and tunnels – WITH ZERO FAILURES.
The Ultracoat system is CE marked and complies with the standard BS EN 1504-2:2004 “Products and systems for protection and repair of concrete structures – part 2 surface protection systems”.
