Screw Piles vs. Traditional Concrete (Restricted Access Sites)
| Factor | Screw Piles | Concrete |
|---|---|---|
| Minimum access width | ✓ 800mm (standard doorway) | ✗ 3-4m (vehicle access required) |
| Delivery logistics | ✓ Hand-carried equipment | ✗ Multiple concrete trucks + pump |
| Street disruption | ✓ Minimal footprint | ✗ Road closures, skips, heavy plant |
| Installation time | ✓ 1-3 days typical | ✗ 1-2 weeks + curing time |
| Neighbour impact | ✓ Quiet, low-profile operation | ✗ Loud mixers, vibration, mess |

Why Choose Us for Your Root-Protection Foundation Project?
Restricted-access sites can be a nightmare with traditional groundwork. Doorways, alleys, courtyards and narrow side passages make concrete foundations slow, messy and expensive.
Our restricted-access screw pile foundations remove those problems. We can install a full foundation system through a gap as narrow as 800mm – roughly the width of a standard door.
Benefits of Screw Pile Foundations for Root Protection Projects
Low-impact installation
No major excavation. No heavy trucks. No large skips filling up the street.

Versatile System
Our screw pile installation team only need around 800mm of access. Ideal for urban sites with no vehicle entry.
Greener Construction
Less digging. Less waste. Far fewer deliveries. A cleaner approach to foundations.
High-quality, long-life components
Our steel piles are galvanised, tested and ISO9001 compliant. Reliable in all soil conditions.
Rapid installation
No curing time and no waiting around. Install today. Build straight away.
Less Disruptive for Neighbours
No loud concrete mixers. No heavy machinery. Perfect for noise-sensitive streets and shared boundaries.
Restricted Access Zones: What You Need to Know
Common restricted-access scenarios:
- Terraced house rear extensions – Access only through the house or narrow side return
- Basement underpinning – Internal strengthening with no external access
- Listed buildings – No vehicle access permitted, preservation requirements
- Mews properties – Cobbled streets, heritage constraints, limited width
- Courtyard developments – Surrounded by existing structures
- Urban infill plots – Tight boundaries on all sides
If you can walk through it, we can install through it.
Restricted-access sites often come with additional planning considerations which we are happy to provide advice on.
What to Expect from Installation
Typical project timeline:
- Day 1: Setting out and excavation
- Days 2-3: Pile installation and beam formwork
- Day 3: Reinforcement installation, final inspection and quality sign-off
- Day 4: Concrete installation
We can complete a full foundation system through a side alley, rear garden gate, or standard internal doorway.
Perfect for London homes, basement underpinning, rear extensions, urban infill projects, and listed buildings where access is severely limited.
