Concrete Doors and Vaults manufacture and install innovative products that offer extreme protection of pump stations, valve chambers, transformers, boreholes & sub-stations, etc.

Concrete & steel Vents


We have sliding concrete doors to protect pump houses/stations, electrical sub-stations, and generator rooms. In addition, we have concrete lids that open by screwing-up, sliding sideways, and rotating over, to secure valve chambers. We also have vaults that protect boreholes and stand-alone electrical control panels, eg. cathodic protection control panels. We also have concrete vents for cooling generator and transformer rooms. We have recently developed high concrete masts with steel cladding, to elevate transformers and solar panels, out of reach. These products can all be customised to the required size.

These products are made from 60 MPa concrete, incorporating up to 17% steel reinforcing bars (by mass) that are so closely spaced so as to make the products essentially chisel-proof.

Our products have extremely robust locking mechanisms.

All mechanical components are essentially maintenance free and are made either from stainless steel or are hot-dipped galvanised, resulting in minimal corrosion even in aggressive environments.
