The Esher basement project, completed in 2018, showcases O’Sullivan Civil Engineering’s specialist capability in contiguous piled basement construction – a sophisticated technique ideal for residential basement development in Surrey locations. Contiguous piling creates a near-continuous perimeter wall through closely-spaced concrete piles, providing robust retention for basement excavation.
Our comprehensive scope encompassed preparation and installation of the piling mat creating a stable working platform, precision contiguous pile installation forming the basement perimeter wall, reinforced concrete capping beam construction providing structural connection across pile heads, systematic excavation within the secure piled enclosure, and complete basement construction. This advanced piling method demonstrates our technical expertise delivering high-quality basement solutions for premium residential properties in Esher and throughout Surrey
