New Underground Drainage Installations
Professional installation of new drainage pipework for extensions, new builds, and property renovations
We install complete underground drainage systems designed to support new kitchens, bathrooms, utility rooms, and structural extensions. Our engineers ensure every pipe run is accurately positioned, correctly sloped, and safely connected to the existing system. This provides a solid drainage foundation before floors, walls, or concrete slabs are constructed.

Trenching, Pipe Laying & Correct Gradients
Precision groundwork to ensure smooth waste flow and long-term system performance
Correct gradient and trench preparation are essential for a reliable drainage system. We excavate, level, and bed pipework using proper materials to maintain consistent fall throughout the run. This prevents future blockages, pooling, and backfall problems, ensuring your drainage performs exactly as intended.

Manhole, Inspection Chamber & Access Point Installation
Install new access chambers to support future maintenance and regulatory compliance
As part of 1st fix drainage, we install new manholes, inspection chambers, and rodding points to provide essential access to your system. Each chamber is set at the correct height, aligned with pipework, and made watertight to prevent ground infiltration. This ensures your new drainage layout remains accessible, safe, and compliant with building regulations.
