Drainage services
Effective drainage protects buildings, hard landscaping and surrounding ground from water damage and recurring problems.
Our drainage work covers new installations, alterations, repairs and upgrades to foul-water and surface-water systems. We install drainage runs with appropriate falls, access points and connections, taking care to support pipework correctly and provide reliable long-term performance.
For surface-water management, we can install channel drains, gullies, attenuation features, soakaways and associated pipework. The correct solution depends on site levels, soil permeability, roof areas, paved surfaces and local requirements.
We can also investigate and repair damaged or poorly performing drainage where excavation is required. Any disturbed ground, paving or landscaping can be reinstated as part of the same package, reducing disruption and avoiding the need to coordinate multiple trades.
What our drainage service can include
How we plan drainage work
We assess the source of the water, available outfalls, existing pipework, site levels and access for future maintenance. New drainage runs are planned with suitable falls, bedding, pipe sizes and inspection points so the system can operate reliably and remain accessible.
Before trenches are closed, levels and connections are checked and pipework is supported correctly. Surface-water solutions are selected around roof areas, paved surfaces, soil conditions and the available space for soakaways, attenuation or controlled discharge.
New systems, alterations and repairs
Drainage work may involve a completely new installation, alterations for an extension, replacement of damaged sections or improvements to an existing system that no longer performs properly. We can coordinate excavation, chambers, gullies, channels and the necessary reinstatement.
Because drainage is closely linked to groundwork and finished levels, handling the connected work together helps prevent low spots, unsuitable falls and repeated disturbance of completed surfaces.
