Gone are the days when all damaged drains had to be excavated and replaced. Patch lining installation is now a fast and effective method for repairing drains in London, including areas like Wembley and surrounding regions.
A patch lining drain repair is essentially a sleeve that is ambiently cured within a damaged drain to restore the structural integrity of a cracked or fractured section of pipe. Installing patch drain linings is also an efficient way of sealing open joints that allow wastewater to leak into the ground, as well as permanently curing root ingress problems by sealing the roots' point of entry.
The process of patch drain lining in London is used to restore drain runs with one or two isolated damaged sections. For example, a drain totaling 10 meters in length might have a circumferential fracture at 5 meters and an open joint at 8 meters. In this scenario, the drain can be repaired cost-effectively with the installation of two patch linings, rather than installing a full drain lining. We offer varying patch lining lengths to our customers—300mm, 600mm, and 1000mm—so it is also possible to cover multiple faults identified close together in a section of drain with the 600mm or 1000mm patch repair kits.
It is our professional opinion, however, that if an underground or above-ground drain has more than two or three isolated faults, it becomes more cost-effective to install a resin-impregnated drain lining to reline the entire drain. The complete relining method may be cheaper for our customers than the cost of three patch lining applications, or it may not be much more expensive than two application
We can patch line repair drains with diameters of 100mm, 150mm, and 225mm, and there is no restriction on the material of the host pipe. A patch lining will adhere to and cure within any drain, such as cast iron, clayware, pitch fibre, or polyvinyl chloride—materials commonly found in residential and commercial drainage systems. Furthermore, our expert lining engineers can patch line damaged 90-degree bends using specialist flexi-patches.
To repair a drain with pipeline patching, we first remove any settled or attached deposits to ensure the patch will cure to the full diameter of the host pipe without any deformity or loss of diameter. We then prepare the high-quality multi-axle glass cloth patch by wetting it out with a mixture of resin and isocyanate, which absorbs into the patch. Ready for installation, the patch is rolled onto and secured to an air packer, then pushed through the pipe to the section requiring repair. Once in place, the packer is attached to a compressor via an inflation hose, inflated, and the pressure is maintained until the chemical mixture undergoes polymerization at ambient temperature. This leaves the hardened patch lining installed within the host pipe, with an air- and water-tight seal. The drain repair is then complete, and the drain is back in use within a maximum of two hours.
If installed by a professional London drain patch lining company, the repair will last for as long as 50 years or even more.
The process of repairing drains with patch linings takes a maximum of 2 hours for each application, with the repaired drain ready for use by the customer directly after the inflation packer has been removed.
There are no limitations on a patch lining repair regarding the various types of pipe materials used for above - or below-ground drains.
The price of a patch lining can vary depending on the diameter of the patch required and any pre-cleaning requirements of the host drain. For example, if the patch repair is needed to cure root ingress, the roots must be removed before installation, which would incur an additional cost. Drain cleaning requirements and access challenges may also pose additional costs, especially if confined space entry equipment is required to access the damaged pipe via a particularly deep manhole chamber.
A patch lining drain repair is not a viable option if the drain to be repaired has completely or partially collapsed with a loss of diameter greater than 15%, as the cured patch molds to the characteristics of the host drain, and the deformity will remain. A broken section of drain with missing pipe is also unsuitable for patch repair. In such cases, a structural cured-in-place pipe lining would be more suitable, as the felt liner material is thicker.
