Deep Drainage Safety
Deep drainage involves high-risk excavation. We utilize advanced temporary works solutions, including drag boxes and trench sheeting, to ensure the safety of our operatives while installing pipes at significant depths.
The Drainage Process
Ensuring efficient flow and compliance with Building Regulations.
Survey & Design
We calculate fall ratios and assess ground conditions (percolation tests) to design the most efficient system.
Excavation
Trenches are dug with laser precision. For deep drainage, trench support systems are installed for safety.
Installation
Pipework, manholes, and inspection chambers are installed on a pea shingle bed to prevent movement.
Testing
The system undergoes air or water pressure testing to ensure it is watertight before backfilling.
