The area is at risk from flooding, and regularly floods during spring tides and winter storms. The new structure features thick reinforced concrete external walls that are designed to stand up to the worst of the weather, with a number of Delta products ready to offer a second line of defence.

Products used include Delta MS500 and Delta PT to the internal faces of the walls prior to plastering.
Applied to all ground floor walls, MS500 features an 8mm studded membrane, and these studs create a drainage path – allowing up to 135 litres/minute/metre of incoming water to be drained – far in excess of the likely demands. It is made from 0.6mm virgin thick high density polyethylene.
Another extremely effective and popular product from the Delta range, Delta PT Lath – which has also been selected for the project – is a high performance polyethylene meshed membrane which is extruded into a series of studs. These studs create a continuous air gap behind the waterproof membrane.
On the face of the membrane a welded mesh that allows plasters and renders to bond efficiently to achieve dry and durable finishes.
For the floors, Delta MS20 is being employed. This is an hdpe membrane with 20mm studs that offer an impressive compressive strength rating of 150kN/m2, and high capacity drainage to easily cope with heavy demands.
