About Premier Substructures

At Premier Substructures, we’ve found ourselves transforming below-ground construction – in one form or another – since the early ‘80s (under our parent company, MBE Fabrications).

Our innovative prefabricated steel method makes constructing a hole in the ground (such as for a lift pit, cellar, gym landing pit, or vehicle maintenance pit) simple and effective, whilst eliminating the risk of leaks and cracks often associated with more traditional methods.

The substructures we provide are fully-welded, built in our factory to +-2mm tolerance, and are installed in a matter of days, making prefabricated steel the best way to de-risk building below ground level.

Our mission statement

It’s always been our goal to offer our clients a professional, seamless service and a far superior and more innovative product at the same commercial cost as an inferior, like-for-like and more commonly used concrete alternative.

We truly believe that how we build substructures below-ground is far superior to anything else available on the market, and once you’ve stood in a steel prefabricated substructure, you begin to realise the long-term issues of water ingress from concrete will never happen.
