Services
Groundwork
Our groundwork services include traditional strip foundations, ring beams, and concrete slabs for domestic extensions and commercial buildings. We prepare sites for tarmac by grading hard standing areas, using certified machinery operators to ensure structural integrity. With expertise in unstable ground solutions, we construct stable foundations that meet exacting safety standards.
Retaining Walls
We install modular pre-cast concrete retaining walls including Permacrib and Anda-Crib systems for heavy loading conditions. These gravity wall solutions utilise interlocking components filled with graded stone to counteract earth pressures. Our 25-year track record with engineering firms ensures durable infrastructure for highway, industrial, and commercial sectors.
Drainage Systems
We design and install plastic ducting systems for electrical, water, and cable protection, including surface water drainage and land drains. Our solutions feature inspection chambers for maintenance access, replacing fragile salt-glazed pipes with durable modern alternatives. This ensures long-term functionality for both residential and commercial properties.
Fencing
We provide palisade, chain link, and weld mesh fencing solutions for industrial and residential sites. Options include galvanised or powder-coated finishes for security and boundary definition. Our installations prioritise site safety while offering aesthetic flexibility through custom colour choices for commercial environments.
