Screw Piles vs. Traditional Concrete (Home Extensions)
| Factor | Screw Piles | Concrete |
|---|---|---|
| Installation + ready time | ✓ 2-3 days, immediate build | ✗ 1-2 weeks + 28 days curing |
| Garden impact | ✓ Minimal – no excavation | ✗ Significant digging, soil removal |
| Access requirements | ✓ 800mm doorway width | ✗ Vehicle access essential |
| Mess & disruption | ✓ Clean, contained operation | ✗ Concrete trucks, mixers, skips |
| Near protected trees | ✓ Passes between roots safely | ✗ Often prohibited or complex |

Benefits of Screw Pile Foundations for Root Protection Projects
Fast & Seamless installation
No curing time. Minimal digging. No waiting around. Screw piles go in quickly so your project keeps moving.

Ideal for restricted access
Our equipment fits through tight gaps, side paths and standard doorways. Perfect for terraced homes.
Cleaner and eco-friendly
Less soil removed. Less waste. Less carbon than concrete footings.
High-quality, long-life components
We use steel galvanised piles and quality-controlled components. Designed for long-term stability.
Build straight away
Once the screw piles and beams are in, your builders can start work instantly.
Less Disruptive for Neighbours
No loud concrete mixers. No heavy machinery. Perfect for noise-sensitive streets and shared boundaries.
Planning Considerations for Extensions
Screw pile foundations can simplify several common extension challenges:
Tree Preservation Orders (TPO)
- Minimal root disturbance often makes screw piles the only viable option
- Can install within root protection zones with proper arboricultural oversight
Party Wall Agreements
- Low-vibration installation minimises impact on neighbouring properties
- Faster completion reduces the disruption period for neighbours
Permitted Development
- Engineered foundation system meets building regulations
- Compatible with standard extension designs and loadings
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
Whether you’re adding a side return, rear extension, wraparound, or garden room, screw piles create a strong, stable base with almost no mess and far less disruption than traditional methods.
Perfect for terraced houses, semi-detached homes with narrow side access, properties with mature trees, and any extension where time and tidiness matter.
