The Problem

Sound familiar?

A builder told you your garden's too steep to build on.

You've been quoted thousands for retaining walls or earthworks.

Your ground is clay, peat, or waterlogged — and concrete keeps cracking.

Tree roots or a TPO mean you can't dig traditional foundations.

Ground screws solve all of it.

35-year structural guarantee, ~60-year expected lifespan depending on ground conditions

FAQ

Frequently asked questions

Can you install on a steep gradient?

Yes. We frequently install on severe slopes. By using longer ground screws on the lower sections, we create a perfectly level base framework without any need for retaining walls or excavation.

Are ground screws safe near protected trees?

Absolutely. We use specialized installation equipment that allows us to gently displace roots rather than severing them. This method is often approved by arboriculturalists for sites with Tree Preservation Orders (TPOs).

What happens if you hit a rock underground?

Our industrial equipment can push past smaller rocks. If we hit a large boulder, we typically pre-drill the ground or make slight micro-adjustments to the screw position to bypass the obstacle.

Will clay soil cause the screws to sink?

No. Our screws are driven deep enough to anchor into stable, load-bearing strata beneath the reactive clay layers. Unlike concrete, they are unaffected by surface ground movement.

How long does a complex installation take?

Even on challenging sites, most domestic foundations are completed within a single day. This is significantly faster than the weeks of groundworks required for traditional concrete.

Is a site survey necessary?

Yes, especially for difficult ground. We provide a free, no-obligation site survey to assess slopes, check ground density, and design the optimal screw layout for your specific terrain.
