Substructure & Basement Construction by Prop Builders

Substructure & Basement Construction

Below ground, there is no margin for error. Our teams build deep basements and underground car parks as reinforced, watertight substructures — engineered to perform for the life of the building.

From piling caps and rafts to retaining walls and suspended decks, we place complex reinforced concrete to exacting tolerances, with waterproofing and finishes coordinated throughout.
