A property in Crawley was experiencing repeated drain blockages and water backing up into the garden. A CCTV inspection carried out by DrainBoss revealed a fractured section of pipe that was allowing water and debris to escape and obstruct flow. Rather than resorting to expensive excavation, our engineers installed a structural drain liner — a no-dig “pipe within a pipe” repair that fully restored the drainage system’s strength and performance. The liner sealed cracks, improved water flow, and provided a long-lasting, cost-effective solution with minimal disruption to the property.
The homeowner contacted DrainBoss after ongoing drainage problems began to affect their garden area, with wastewater occasionally overflowing during heavy rain. Initial rodding attempts by another contractor had only offered short-term relief, prompting the need for a more detailed investigation.
Using advanced CCTV inspection technology, our engineers examined the internal condition of the underground drain. The footage revealed a fractured and partially collapsed section of pipe approximately three metres from the inspection chamber. This damage was causing debris to accumulate, restricting flow, and increasing the risk of further deterioration if left untreated.
To provide a permanent repair without the need for excavation, DrainBoss recommended a structural drain lining installation. Our technicians first prepared the damaged pipe by carrying out a thorough clean using high-pressure water jetting to remove all silt, scale, and loose material. Once the surface was properly prepared, a resin-impregnated liner was inserted into the drain and inflated to conform tightly to the existing pipe’s interior.
After curing, the liner formed a tough, seamless “pipe within a pipe,” restoring full structural integrity to the system. A final post-installation CCTV survey confirmed that the repair was complete, with a smooth, watertight surface ensuring efficient flow throughout the length of the drain.
The no-dig lining repair was completed within a single day, avoiding any excavation, noise, or disturbance to the property. The newly lined section eliminated the source of blockages and significantly improved overall flow performance. The homeowner was particularly pleased with how quickly the issue was resolved and impressed by the clean, non-invasive process. With the structural liner in place, the system now benefits from a durable, long-term solution guaranteed to last for many years.
DrainBoss Comment: Drain lining is an excellent example of how modern, trenchless technology can restore damaged drains without digging or disruption. This Crawley project highlights the effectiveness of structural relining as a permanent, watertight solution that strengthens existing pipes, prevents future leaks, and provides outstanding value compared to traditional excavation repairs.
