Below-Ground Drainage

Below-Ground Drainage Design

Coordinated drainage design is a critical component of successful substructure engineering. We provide in-house below-ground foul and surface water drainage design for domestic projects, delivering clear layouts and details required for Building Regulations approval.

For larger or more complex schemes—particularly those requiring formal Sustainable Drainage Systems (SuDS), surface water attenuation calculations, or complex hydraulic modeling—we partner with trusted specialist sub-consultants.

By managing this process directly, we ensure all below-ground drainage arrangements are fully integrated with our structural foundation designs from early concept through to approval and construction.
