Groundworks in Shepperton
From the banks of the Thames to the historic Village Square. We provide TW17 with specialized flood-resilient engineering, island logistics, and dewatering solutions.
Engineered for the Floodplain
Shepperton is unique—the "Shepperton Gravels" are named after your town. We understand how this highly permeable soil interacts with the River Ash and Thames to create complex ground conditions.
The Shepperton Gravel Member
The town sits on the "Type Location" for the Shepperton Gravel Member—a layer of river terrace deposits that is exceptionally strong but highly porous. In winter, groundwater levels here rise rapidly, often mirroring the levels of the Thames and the Ash.
This means traditional strip foundations in Old Shepperton or Lower Halliford are at risk of "washing out" during excavation. We use specialized temporary works to hold back the water while we pour reinforced concrete.
We employ high-capacity trash pumps and well-point dewatering systems to artificially lower the local water table, allowing us to construct dry, secure basements and foundations.
For riverside properties (e.g., Towpath or The Creek), we install interlocking sheet piles to create watertight cofferdams, isolating the work area from the river.
River Ash & Thames Defense
Shepperton is surrounded by water. The River Ash creates specific "flash" flood risks near the Studios, while the Thames dictates groundwater pressure. We specialize in Property Level Flood Resilience (PLFR).
Non-Return Valves
Crucial for TW17. We install industrial-grade valves that seal your property off from the main sewer line when the river level rises, preventing back-surge.
Tanking Systems
We use Type A (barrier) and Type C (cavity drain) waterproofing systems to ensure basements and semi-basements remain dry even under hydrostatic pressure.
Void Formers
To meet Spelthorne's flood compensation rules, we can build sub-floor voids that allow floodwater to flow beneath your extension without entering the property.
