Drainage ContractorsFoul, surface water and channel drainage

Foul and surface water drainage for retail and commercial sites, installed by our own team as a core part of the groundworks package. Runs, chambers, channel drains and connections are laid to the engineer's design and are in the ground before the kerbs and surfacing follow, so nothing finished has to be dug up again.

What is included

Below ground, done once

01

Surface water drainage

Carrier drains, gullies and chambers taking water off car parks, service yards and roofs, laid to the falls and levels on the drainage drawings.

02

Foul drainage

Foul runs, inspection chambers and connections from the building to the outfall, bedded and surrounded to the specification.

03

Channel drains

Linear channel drainage along thresholds, crossings and yard edges, set in concrete and tied into the kerb line so the finished levels work.

04

Chambers and connections

Chambers built or set to level, with connections made into the existing network as the drawings and the consents allow.

05

Sequenced with the package

Drainage goes in ahead of the kerbs, the duct crossings and the sub-base. Each trench is opened once and the surfacing is laid over finished work.

06

Checked before it is covered

Runs are checked and tested before backfill and surfacing, so there are no surprises under a finished car park.

Questions

Asked at tender

What types of drainage do you install?

Foul and surface water runs, channel drains, chambers and connections, installed to the engineer's drainage design for retail and commercial sites.

Is drainage priced as part of the groundworks package?

Usually, yes. Drainage is one of the core parts of our groundworks packages and is priced from the drainage drawings in your tender pack. If your requirement is drainage only, send the drawings and we will tell you straight whether it suits us.

Where have you installed drainage recently?

At ALDI Liskeard in Cornwall, where our package includes the surface water drainage and channel drains for the store extension and the new car park.

How do you stop drainage holding up the other trades?

By sequencing it first. Drainage goes in ahead of the kerbs, the duct crossings and the sub-base, and it is checked before it is covered. The trades that follow work over finished ground.

Do you work in Wales, where SuDS approval applies?

Yes. Much of our work is in South Wales, where new developments need their surface water drainage approved by the SuDS Approval Body before construction starts. We build to the approved drainage design.
