Previously, the common approach to repairing damaged and buried drain pipes involved extensive excavation and replacement, often proving challenging due to the pipes being located underground at considerable depths. Complicating matters further, some drainage systems were concealed beneath vital infrastructures like driveways.
Fortunately, advancements in technology have revolutionized drainage solutions, offering a faster, cost-effective, and simpler alternative known as drain relining.
Initiating Drain Relining
Identifying drainage issues isn’t always straightforward, often necessitating a thorough drainage survey conducted by a professional before commencing any repair or relining endeavors. Thus, conducting a drain survey before undertaking such works is strongly advised.
Understanding Drain Relining
Drain relining involves the repair of damaged drainage systems by installing a new lining within the existing, compromised pipework, bypassing the conventional method of extensive excavation. It’s a non-destructive “No dig” repair technique used to address leaks, cracks, and persistent blockages, proving highly favorable for businesses and commercial properties due to minimal downtime.
The Relining Process
To commence drain relining, the initial steps involve cleansing and de-scaling the pipes slated for relining, typically achieved through high-pressure water jetting to eliminate scale and sediment deposits. This prepares the pipe for the relining procedure.
Subsequently, a UPVC relining sleeve is installed and inflated with air, curing over a few hours. After the curing period, the inflation tube is removed, and the newly relined section is cleansed to remove excess resin solution.
Though drains may be temporarily out of commission, this method offers the quickest resolution, sealing the new lining to the pipes, effectively erasing any prior damage. Moreover, the non-destructive nature of relining ensures no noticeable disturbance post-repair.
