Collapsed Drain Repair in Swanage – No-Dig Trenchless Solution
If you’re facing a collapsed drain in Swanage or the surrounding Dorset area, excavation isn’t your only option. We recently helped a local holiday let owner solve an urgent drainage problem — without digging up the ground or delaying their guest arrival.
This trenchless drain repair was completed in just under two hours using a no-dig patch lining method. Here’s how it worked.
Emergency Drain Callout at a Holiday Let
We were called to a property in Swanage, Dorset, after the owner noticed recurring blockages. With new guests due to arrive the same day, there was no time to dig. Our emergency drainage team arrived on-site to inspect the system.
Step 1: CCTV Drain Survey
Our first step was a CCTV drain survey, which revealed a collapsed interceptor trap — an old-style u-bend where the base had completely disintegrated. Rubble and debris had fallen into the pipework, causing a serious blockage.
We thoroughly cleaned the system to prepare the damaged area for repair.
Step 2: Preparing the Patch Liner
Instead of excavation, we used a fibreglass patch liner impregnated with a two-part epoxy resin. This was wrapped around an inflatable rubber bladder designed to hold the patch in place while it cured inside the pipe.
Step 3: Inserting and Curing the Patch
The patch and bladder were inserted directly into the collapsed area of the pipe. Once in position, we inflated the bladder to press the patch firmly against the pipe walls. After around 45 minutes, the resin had cured and bonded — creating a watertight, structural lining with no disruption above ground.
Step 4: Final Inspection and Result
We ran the camera back through the system to inspect the work. The patched area was perfectly sealed and aligned with the plastic-to-clay transition point. No excavation was needed, and the guests were able to check in on time.
From start to finish, the job took just two hours — compared to half a day or more if we’d had to dig.
