Choosing the Right Screw

Ground Screws in Four Sizes

Most garden rooms go in on our standard 1.25m — but the right spec depends on your ground conditions and what you're building. We'll always tell you what's correct for your project.

1m
Shallow & Light
  • Lighter garden structures
  • Shallow topsoil
  • Low-load applications
  • Access-constrained sites
Most Common
1.25m
Our Standard
  • Garden rooms & annexes
  • All standard SE England soils
  • Most residential projects
  • Proven across 500+ installs
1.5m
Deeper Reach
  • Softer or wetter ground
  • Sloped sites
  • Heavier structures
  • Where 1.25m isn't sufficient
2m
Maximum Depth
  • Challenging ground conditions
  • Commercial projects
  • Large or multi-storey structures
  • Deep bearing layer required

The Better Choice

Why Ground Screws Beat Concrete for Garden Rooms

Faster, cleaner and more practical in almost every situation. Here's why the industry is moving away from concrete.

Same-day installation — no cure time

Screws go in, level up, done. Start building today — not after waiting 24–48 hours for concrete to set.

No excavation, no mess

No skips, no digging, no spoil. The garden looks the same after we leave as before we arrived.

Works in all ground conditions

Clay, loam, sandy soil — ground screws perform reliably across all standard South East England ground types.

Level, square and accurate

We install to precise levels so your garden room sits perfectly from day one. Accuracy at foundation stage is everything.

About Ground Down

Six Years of Experience. The Same Approach Every Time.

Ground Down grew out of practical experience in the garden room industry. It started with ground screw installations for contacts in the trade — word spread, and before long we were working with multiple garden room companies across South East England.

Over six years and 500+ installations, we have seen what works. Our focus is straightforward: turn up on time, use the right spec, install correctly, and leave the site clean so you can start building the same day.

No concrete, no mess, no delays. Just a foundation that is ready to build on.
