Our piling teams have successfully installed load bearing piles in environments ranging from waterlogged peats and loose sands to hard rock strata. We routinely achieve rock sockets in mudstones, sandstones, and basalt, ensuring maximum pile capacity and structural stability.

As the largest Cased CFA piling specialist in the UK and Ireland, DAWSON-WAM can provide:

• Piling within 100mm of adjacent structures
• Piling into tight corners
• Flighting risk elimination for improved bore stability
• The ability to bore through obstructions, mass concrete, and medium-strong rock
• Low-noise, vibration-free piling suitable for urban, sensitive, and restricted-access sites

This capability allows us to offer precision installation, ability to work in constricted sites where others can, delivering cost and programme certainty, even in challenging geotechnical conditions.

From small residential developments requiring just fifty piles to large-scale industrial or commercial schemes involving several thousand piles, DAWSON-WAM has the capacity to deliver projects of all sizes efficiently and to the highest standards.

In addition to pile installation, we offer complete foundation packages, including:

• Temporary works platforms and propping
• Pile caps
• Ground beams
• Reinforced concrete works from pile head to superstructure interface
• Water infrastructure

By delivering these services in-house, we ensure quality control, programme efficiency, and seamless coordination between all phases of the foundation works.

Every piling project begins with a detailed geotechnical assessment to determine ground conditions, load requirements, and site constraints. With our inhouse geotechnical department engineers, we:

• Analyse soil and rock data to determine the most suitable pile type and installation method.
• Calculate required load capacity, factoring in safety margins and long-term settlement behaviour.
• Select optimal pile diameters and depths to achieve structural performance while minimising cost.
• Assess environmental and access constraints to choose the quietest, least disruptive installation method possible.

This technical process ensures each pile is engineered for maximum performance, efficiency, and durability, whether the project involves deep rock sockets, challenging waterlogged soils, or restricted city centre sites.
