Premier Substructures
Transforming below ground construction
Whenever a hole in the ground, such as a lift pit, cellar, machine base, gym landing pit or vehicle maintenance pit, needs to be constructed our approach almost always out performs reinforced concrete, precast concrete or bricks and blocks.

Offsite & Fast-Track Construction
By taking substructure fabrication off-site we make a significant contribution to fast-track construction. Installations usually taking weeks or even months using traditional methods can be completed in days by our experienced installation teams.
If time is not a significant driver there are so many other benefits to adopting the Premier Substructures approach.
- Class 2 welding ensures there is no ingress of water and no egress of pollutants
- Tolerances are much tighter -+3mm
- A much safer method of construction as operatives are not required to enter an excavation
- Simplified site management
- Fixtures and accessories can be pre-fitted at the factory
- More accurate costings possible
- Significantly lowers the risk compared to traditional insitu or precast construction methods
Our method of below ground construction benefits clients, end users, contractors, architects and engineers.
It is now possible to adopt below ground what works so well above ground.
Over the years, while there has been little improvement in below ground construction methods and services, above ground construction has benefitted significantly from, amongst other things, off site fabrication, computer modelling and improvements in on-site construction methods.
Premier Substructures is beginning to bring these advantages to below ground construction, thereby leading to benefits such as reduced construction times and significant cost savings.
Over the last few years Premier Substructures has successfully completed contracts that have involved everything from the manufacture and installation of gym landing pits to the bases for very large industrial machines.
Our Five Stage Process
To provide customers with a reliable, comprehensive, service we have developed the following five stage approach.
-
Stage 1 - Concept
Early help and advice given.
-
Stage 2 - Design
All designs are produced by our design engineers using the latest CAD facilities.
-
Stage 3 - Factory Build
Built under factory conditions using the latest techniques including lasers.
-
Stage 4 - Delivery
The completed modules are delivered direct to site.
-
Stage 5 - Installation
Larger projects are usually manufactured in module form and bolted and welded together on site.
The high quality substructures produced today result from years’ of continuous improvement
Continuous improvement started in the early days of MBE when the company was producing high quality tanks for the effluent market. The experience learned in the early fabrication business, followed by the development of the vehicle pits business, is reflected in the substructures produced today.

Material
All fabrication is from mild steel, stainless steel or aluminum depending on what the substructure will be used for.

Welded Construction
On larger projects, where they are fabricated and installed in modules, the jointing methods used ensure the final assembly is watertight.

Finish
Outside surfaces – Black bitumen as standard .
Inside – Polyurethane gloss as standard or to customers’ own requirements.
