Essentially, relining is when a new drain is installed inside the old one. This creates a reinforced coating that protects against cracks and other damage. The process should begin with a thorough inspection of the drains with our CCTV survey system, to determine the exact location and extent of any damage, before the pipes are fully flushed out using high powered water jetting. This stage is important, as it is crucial for the internal wall of the drains to have a clean and even surface for the lining to attach itself to.
Traditional repairs can be an expensive and often difficult operation, generally involving digging up a large surface in order to remove and replace any damaged drainage. The fact that drains may be buried beneath the earth, often under concrete, tarmac or walls, means that a lot of upheavel may be required in order to carry out essential work.
With our no-dig relining repairs this upheavel can be eliminated and is the easiest and least invasive solution saving the customer potentially large disruptions and costs. Re-lining a drain can repair cracks, holes, displaced joints and prevent roots from entering the drinage system.
The relining process involves impregnating a drain liner with a 3 part resin which is then inserted inside the old pipe. This is then inflated with our inflation hose filled with either water or air to hold the new liner in place until the resin has completed it's curing process.
The inflation hose is then removed, leaving a brand new drain pipe inside the original. Depending on specific site demands, the liner can either be installed in one section or in smaller overlapping sections.
Our drain relining services are priced competively with each job priced according to factors such as size of pipe, location and access.
Sometimes a drainage system may have one specific issue such as a crack or hole. In this instance it may not be cost effective to re line the whole length of the drain in order to repair one small area. We can install 'patch liners' in this instance. This is a cheaper alternative and where we can we will always recommend this to save the customer money.
