As a leading piling company in London and Essex, Prime Piling delivers expert solutions in complex ground engineering, including piled raft foundation systems and mini piled underpinning. Our work supports both new developments and structural stabilisation projects across urban and constrained sites.
**What is a Piled Raft Foundation?**A piled raft foundation combines deep foundation piles with a raft (mat) slab. Piles are installed to transfer loads to stronger soil or rock strata, while the raft distributes structural loads across a broad area. The interaction between the piles, the raft, and the underlying soil is critical to performance and must be carefully engineered.
Key Interactions in Piled Raft Design:
-
Pile–Soil Interaction: Load transfer efficiency from pile to ground
-
Raft–Soil Interaction: Contact pressure distribution beneath the raft
-
Pile–Pile Interaction: Group effects influencing load sharing
-
Pile–Raft Interaction: Combined stiffness and settlement control
Benefits of Piled Raft Foundations:
-
Reduces total and differential settlement
-
Enhances resistance to horizontal (lateral) forces
-
Supports high axial loads – ideal for tall or heavily loaded structures
-
Suitable where rock socketing is not feasible
Our team works closely with structural and geotechnical engineers to optimise design parameters such as load capacity, settlement limits, raft bending moments, and individual pile loading to ensure compliant, efficient foundations.
Mini Piled Underpinning ServicesPrime Piling also provides mini piled underpinning for properties requiring structural strengthening. This technique is especially effective for restricted access sites, weak ground conditions, or where traditional underpinning is impractical. We offer both open-hole and driven systems depending on site-specific constraints.
Comprehensive Foundation Solutions in London & EssexFrom modern raft-on-pile systems to heritage building underpinning, Prime Piling is a trusted partner for safe, compliant, and efficient groundworks. All services are delivered by qualified operatives with full project oversight and quality control.
