Are you a main contractor in search of reliable precast concrete companies in the UK for your below-ground substructure?

Regardless of why you need a substructure (be it a cellar, lift pit, machine base sump, vehicle maintenance pit, machine pit etc.), precast concrete can be a good alternative to in situ; when the conditions are right and on the right project.

Whether this is your first time constructing below-ground, or you’ve had a bad experience with a previous company, finding a reliable experienced subcontractor is absolutely vital. That’s why I wanted to compile this handy list. I’ve looked at 7 of the most popular precast concrete companies in the UK, so you can decide which one is right for you.

So, without further ado, here’s an overview of the 7 best precast concrete companies in the UK (in no particular order).

Advice from a specialist subcontractor

If you’re looking for the best precast concrete company for your project, my advice would be to contact them in plenty of time and ensure they can meet all of your requirements. It may also be worth discussing with a structural engineer whether precast is the right route to go down for your project.

TIP: Did you know there’s another alternative to precast concrete? Check out our blog: ‘What is Steel Prefabrication Below-Ground and How Does it Work?’ to learn more.

A good precast concrete company (or subcontractor) should be able to talk you through all of your options, provide a detailed quotation based on your requirements, and show you previous examples of their work when constructing below-ground substructures.

Asking the right questions and doing a bit of research into the company will help ensure you’re choosing the best subcontractor for the job.
