Groundworks in Sutton
We are your local groundworks partner. Delivering compliant foundations, basements, and drainage systems across the London Borough of Sutton.
Engineered for Sutton
Sutton's geology is starkly divided. The southern wards (Belmont, Cheam) sit on free-draining Chalk, while the north (St Helier, Rosehill) relies on heavy London Clay. We adapt our engineering to your specific postcode.
The North/South Divide
In South Sutton and Cheam, the underlying Chalk allows for excellent drainage but requires careful investigation for solution features (voids) before piling. Basements here are highly viable.
In North Sutton (St Helier), the ground shifts to London Clay. This soil expands and contracts with moisture changes, posing a subsidence risk. Here, we use deep piled foundations with heave protection to guarantee stability.
We utilize deep-bore soakaways to manage surface water, complying with strict local environmental standards to prevent groundwater contamination.
We implement reinforced ring beams and anti-heave void formers (Claybord) to isolate your structure from the movement of the clay soil.
SUDs Compliance
The London Borough of Sutton is rigorous about Sustainable Urban Drainage Systems (SUDs). Paving over front gardens in Sutton now requires planning permission unless permeable materials are used. We ensure full compliance.
Permeable Paving
We install specialized sub-bases and porous surfaces that allow rainwater to drain naturally, avoiding the need for planning applications for driveways.
Soakaway Crates
For extensions in clay areas where natural infiltration is poor, we design attenuation systems that hold water and release it slowly to the sewer.
Basement Pumps
We install dual-pump stations with battery backups for basements in South Sutton, ensuring protection against rising groundwater tables.
