Drain lining can be a cost effective method of repair if a pipe is cracked, broken, displaced, has a hole or some other problem.
A drain liner is a polyester, epoxy, vinylester or silicate resin impregnated felt liner or a silicate resin impregnated fiberglass patch which is then inserted into a drain or pipe run to make a structural repair.
We can carry out drain lining and patch repairs on pipes from as small as 7omm up to 1500mm in internal diameter.
When an excavation to repair a damaged drain is likely to cause excessive interruption and inconvenience it is often possible to insert a liner (for the complete length of line or part section of, with no distance limit) or patch repair (for short lengths upto 1 metre long) to improve the flow characteristics of the line or seal a section to prevent leakage.
Drain lining is an established and well proven method of repair that reduces the level of disruption and can be carried out on existing pipe and drain runs. This method of repair does not remove any running backfalls (slump in the line) but does reduce further degradation of the line.
We use the latest drain lining technology, allowing us to line any length of run.
All our liners no matter how large or small are pre vacuumed and the resin impregnated under vacuum in accordance to WRc standards, unlike many other companies who will stamp the resin in without removing the air so allowing micro bubbles within the liner, and the consequent reduction in liner strength.
The lining is constructed from a sealed polyester felt tube of varying thickness dependent upon depth and damage, which is impregnated under vacuum with resin (type of resin is dependent upon the lines use and location).
For additional details on appropriate resins call 02920 553370 and ask for the drain lining engineer.
This line is then inverted into the drain run so that the resin is on the outside of the tube as it goes into the drain enabling it to key into all the cracks and joints and fill them at the same time. A second tube is then inserted along the length of the liner and inflated and pressurised so placing a uniform pressure within the liner during the curing period. On completion of the cure time the calibration hose (used to inflate the liner to size) is removed, and the lining is now fitted tightly against the inner wall of the existing drain.
Though the drain run has been reduced in diameter by a small percentage the capacity for flow will have been improved considerably.
For further information on drain liners and relining call 02920 553370 to speak to a B.Eng(hons.) engineer, who will be able to provide you with an estimate.
When considering which contractor to use ensure that you use one that pre vacuums and impregnates the liner under vacuum to ensure full strength and integrity of the liner.
If the liner is to be installed in the vicinity of a building that is used by people with respiratory problems ie elderly people, or where an above normal level of styrenes in the atmosphere is likely to cause a problem, this should be noted; the resin used can be changed from a polyester resin to an epoxy or silicate resin at an additional cost.
