Knight Build has extensive experience in underpinning of existing structures, listed buildings and forming reinforced concrete retaining walls in an underpin sequence where working space is restricted.


In addition, we have developed a waterproofing system to allow basements to be constructed with reinforced underpins forming the basement perimeter walls, allowing clients to maximise the achievable square footage.


Knight Build has also introduced the jacking of underpins site-wide and have been extremely successful in restricting movement to party walls.
