New River Village, Hornsey

This old Thames Water plant was an old water treatment works, covering 14-acres in Hornsey, North London N8. The site comprises of a mix of studio apartments, 3 and 4 bedroom apartments including a proportion of affordable housing.

The site had become redundant as a result of the construction of the new Thames Water Ring Main, but is located in an extremely wet site being adjacent to the New River & reservoir, so a complete waterproofing solution of the substructure was paramount.

Concrete containing Xypex Admix C1000NF was specified by the structural engineer. Its self-healing nature was considered as the best solution to withhold the natural hydrostatic pressure from the local bodies of water.

Along with the C1000NF Admix in the in-situ cast concrete, the Xypex Concentrate product was also specified within all the construction joints to ensure continuous, seamless waterproofing throughout the structure.

In this high risk environment Xypex was the sole waterproofing solution within the basement car park.
