Describe the drain and its location
Fill in the form with the property address and a description of the drain or sewer you need dealt with. Say whether it is a surface water drain, a foul drain or a combined run. Note roughly where it sits on the plot, whether it is under a slab, a driveway or open ground, and whether any part of it is still in use. The quote is free.
A specialist calls to go over the detail
A drain specialist will call you to ask about the pipe material, the approximate depth, the run length and what triggered the decision to decommission or fill. They may ask about neighbouring drains, manholes or connections that could affect the work.
Survey of the drain run
Where the layout is not already known, the specialist carries out a drain abandonment survey using CCTV equipment. The camera records the condition of the pipe, any existing blockages, junctions with live drains and the precise route. This information determines the filling method and the volume of material required.
Written quote and method statement
Once the survey findings are reviewed, the specialist sets out a written quote. It covers the filling material, whether foam grout, concrete or another approved fill, the method for sealing entry and exit points, and any excavation needed. You see the scope before any work begins.
The filling work
The specialist fills the redundant drain using the method the survey supports. Grout or concrete is pumped into the pipe until the run is fully consolidated. Entry points, junctions and manholes connected to the decommissioned section are sealed. Where a section of pipe needs removing before filling, that work is done first.
Verification and sign-off
After filling, the specialist checks that the material has set correctly and that no voids remain. Where the work requires documentation for a lender, insurer or local authority, the specialist produces a completion record stating the drain location, the material used, the date of the work and the extent of the run that was treated.
