Groundworks in Reigate
We are your local engineers just off the M25. Delivering basement construction, slope retention, and complex drainage for the Greensand Ridge and Reigate Hill.
Built on the Greensand Ridge
Reigate presents a unique geological mix. From the historic "Silver Sand" of the town centre to the Gault Clay towards Woodhatch. We have the technical expertise to handle mining risk zones and steep gradients alike.
Sand, Clay & Mining Risk
The topography of Reigate (RH2) is defined by the Lower Greensand formation. While this offers excellent drainage in areas like Priory Park and the Heath, it introduces stability risks from historic sand mining.
Conversely, properties towards Wray Common and Redhill often sit on Gault Clay, requiring heave protection. We adapt our foundation design—whether traditional strip, raft, or piling—to the specific strata of your postcode.
In sandy zones, we utilize the natural drainage capabilities for efficient soakaways, but enforce strict trench support (shoring) during excavation to prevent collapse.
For properties on the slopes of Reigate Hill, we design reinforced concrete retaining walls and contiguous piling to stabilize the chalk escarpment.
Reigate Surface Water Management
While the sandy high grounds drain well, runoff often pools in the lower clay valleys (Woodhatch & South Park). We implement Reigate & Banstead compliant SUDS (Sustainable Drainage Systems) to manage this flow.
Crate Soakaways
High-void cellular storage crates wrapped in geotextile, perfect for the sandy soils of Reigate Heath, allowing rapid dispersion of rainwater.
Basement Waterproofing
Type B (structural integral protection) waterproofing for basements, essential in Reigate's historic properties where the water table can fluctuate.
Attenuation Tanks
For clay areas near Woodhatch, we install large capacity flow-control tanks to hold storm water and release it slowly into the sewer system.
