Groundworks in Richmond
Operating from Richmond Hill to Kew Gardens. We deliver expert basement retrofits, slope retention, and flood defense for properties along the Thames.
High-Spec Engineering for TW9
Richmond requires a delicate touch. Whether underpinning a Victorian terrace in "The Alberts" or piling a modern extension in Kew, we handle the logistics of narrow streets and Red Routes with precision.
The Hill vs. The River
Richmond's geology is split. On the high ground of Richmond Hill and Petersham, we encounter London Clay which is prone to seasonal movement, often requiring contiguous piling for slope retention.
Down towards the river in Kew and the town center, the ground consists of permeable River Terrace Gravels with a high water table. Here, our focus shifts to dewatering and waterproof concrete structures.
For properties on steep gradients like Star and Garter Hill, we install reinforced retaining walls and piling to prevent ground slip during excavation.
Expert underpinning and excavation for new basements under existing properties, maximizing square footage in high-value zones.
Flood Defense & Waterproofing
With the Thames being tidal at Richmond, flood risk is a genuine concern for riverside properties. We implement robust defense strategies compliant with the Environment Agency and Richmond Council.
Tanking Systems
Type C cavity drain membranes and sump pump systems to ensure basements remain dry even when the local water table rises.
Tidal Valves
Installation of non-return valves to protect drainage systems from back-surge during high tides and heavy rainfall events.
Root Protection
Installation of cellular confinement systems (Geoweb) for driveways to protect the root zones of Richmond's protected TPO trees.
