Structural Lining

About: Structural Lining

Claret Civil Engineering Ltd can provide a comprehensive condition surveying service and advice on the suitability of a structural lining solution.

We believe there is not just one solution to fit all defective pipes. Our expert knowledge allows us to advise clients of what materials are best suited to their requirements, along with the best installation and curing method. Structural lining is an effective way to repair and extend the working life of failing, below-ground pipework that avoids surface disturbance, traffic disruption and the considerable additional costs associated with excavating and replacing a failed section of pipe.

Key benefits

A proven and tested trenchless structural repair

Minimises time on-site and disruption to public highways

Can facilitate diameters ranging from 100mm to 1800mm

Prevents root and water ingress

Reduced carbon footprint

Dedicated & experienced teams to deliver multiple applications

CIPP LINING

If your underground sewer is suffering from root ingress, joint displacements or cracking of the pipework over a long distance then our CIPP (cured-in-place-pipe lining) is the solution. CIPP is a semi structural/structural liner (depending on its design) which is usually installed between two manholes, removing the need for excavation to repair the pipe thus saving on time and money but leaving you with a rehabilitated sewer with a 50-year life expectancy. Claret Lining Division offer all methods of installation and curing capabilities to suit the conditions of the pipe and the environment around it. Typical methods of cure are:
  • Hot Cure (Water & Steam)
  • Ambient Cure
  • LED Cure
  • UV Cure
All our materials are WRC approved and installed by experienced qualified personnel. We are also corporate members of the UKSTT.

How it works:

The new liner is then inflated with air or filled with water where the resins can then be cured through a thermal cure (usually steam, hot water or ambiently) or with ultraviolet/LED lights to then form a new pipe within the existing pipe.

PATCH LINING

We can install our structural patches from 0.5m up to 3m in length, with access from a nearby manhole, removing the need to dig up your landscape / hardscape saving on time and money but leaving you with a good as new sewer with a 50-year life expectancy. With a quick setting resin the pipe can be returned to service within the hour.

How it works:

The patch material is a pre-cut piece of reinforced fibreglass that has been saturated in a silicate resin. The materials are positioned and rolled centrally to a packer and then inserted into the sewer and then winched into the position of the defective area. The patch is then inflated so that the materials press firmly against the host pipe and then left in position for a nominal period for the resins to cure hard, thus restoring the existing host pipe to a sound and structural condition.
