Techniques

FK Lowry offers a full range of Piling Techniques. We have many years’ experience using these techniques in providing cost effective foundations solutions.

Replacement Techniques

Rotary Bored Piles

Large Diameter Rotary Bored piling involves drilling deep circular piles using specialist rotary bored piling rigs and tooling. The technique is designed for projects requiring high load capacities or deep foundation solutions.

This system is commonly used on major infrastructure, commercial and multi-storey developments where ground conditions or structural loading requirements demand robust foundation solutions.

Typical applications include:

• High-rise developments
• Bridge structures
• Infrastructure projects
• Energy sector developments
• Heavy industrial structures

Continuous Flight Auger (CFA) Piling

Continuous Flight Auger (CFA) piling is a high-production foundation solution installed using a continuous hollow stem auger. Concrete is pumped through the auger stem as the auger is withdrawn, before reinforcement is installed into the freshly concreted pile.

CFA piling is widely used across commercial, residential, industrial and infrastructure projects due to its speed, versatility and ability to operate in a wide range of ground conditions.

Typical applications include:

• Commercial developments
• Residential schemes
• Retaining structures
• Industrial units
• Infrastructure and transport projects

Retaining Walls (Contiguous & Secant)

Continuous and secant piled walls are retaining solutions used to provide ground support and excavation stability for basements, infrastructure and deep excavations.

Contiguous walls utilise closely spaced piles, while secant walls use interlocking piles to create a continuous retaining barrier.

Typical applications include:

• Base construction
• Retaining structures
• Urban excavations
• Infrastructure projects
• Water-retaining structures

Displacement Techniques

Driven Precast Concrete Piling

Driven precast concrete piling involves driving pre-manufactured reinforced concrete piles into the ground using specialist piling rigs.

This method provides a highly efficient displacement piling solution with excellent quality control and high structural performance.

Typical applications include:

• Industrial developments
• Warehousing
• Residential developments
• Infrastructure projects
• Marine and waterfront structures

Driven Steel Tube & H Sections

Driven steel tube and H section piling provides a versatile displacement piling solution capable of achieving high capabilities in difficult ground conditions.

This system is commonly used where deep penetration or high structural loads are required.

Typical applications include:

• Marine works
• Bridge structures
• Temporary works
• Industrial developments
• Restricted access projects

Bored Displacement Piling

Bored displacement piling is a low-spoil piling technique that displaces the ground laterally during installation rather than removing it.

This system combines the benefits of displacement piling with reduced environmental impact and efficient installation rates.

Typical applications include:

• Residential developments
• Commercial projects
• Infrastructure works
• Environmentally sensitive sites

Marine Piling

Marine piling solutions are designed for projects located in or adjacent to water environments, including ports, harbours, jetties and waterfront infrastructure.

These works often require specialist plant, marine coordination and challenging installation conditions.

Typical applications include:

• Harbours and ports
• Waterfront developments
• Bridge structures
• Coastal infrastructure
• Marine retaining structures

Additional Services

Ground Improvement

Ground improvement techniques enhance the engineering properties of unsuitable soils to improve stability, settlement performance and load carrying capability.

These methods can provide cost-effective alternatives to deep foundations depending on project requirements and ground conditions.

Rigid Inclusions

Rigid inclusions are ground improvement elements installed to reduce settlement and improve load distribution within weak ground conditions.

This technique is increasingly used beneath industrial slabs, embankments and heavily loaded structures.

Plant

Our plant investment also covers a wide range of quality equipment and fleet vehicles.
