Drainlayer in Half Moon Bay

We prepare the trench base and lay the specified drainage pipework at the checked levels. Junctions, bends and risers follow the agreed layout. Pipe support matters throughout the run, including beneath joints and where drainage passes through the slab. Foundation penetrations and clearances are coordinated with the designer’s details before surrounding work closes them in.

We repair or replace the agreed section of existing drainage where the connection requires it. Open pipe ends are capped against concrete and debris. Restricted drainlaying belongs with an appropriately authorised person; use the PGDB register to check the person undertaking it. Give the builder clear riser positions to protect during reinforcing and slab preparation.

Testing comes while the pipework remains accessible for checking and correction. We check the laid route, levels, joints and outlet positions against the drawings, and complete the testing required for the work. Arrange required inspections at the appropriate stage. Do not bury an inspection point beneath fill or reinforcing before the relevant check is completed.

For a new wastewater connection, include Watercare’s application, inspection and completion steps in the programme. Keep that connection process separate from the concrete booking. Once testing and inspection requirements are satisfied, coordinate backfilling and compaction with the slab team. Recheck exposed risers for movement or damage before concrete placement.

Record the installed route, junctions and connection location before covering them. Keep measurements tied to identifiable building points, together with photographs, test records and applicable inspection documents. Give the owner and builder the drainage layout, including agreed changes, so later alterations start with a useful record of what lies below concrete.

At handover, identify which trenches have been backfilled and which areas remain for the builder’s slab preparation or surface reinstatement. Leave pipe openings protected and access points identifiable. Explain any outstanding drainage connection work and who coordinates it, so the owner understands what is complete before the floor hides the installation.
