Services
Groundworks
We undertake all aspects of groundwork, including deep drainage, foundations, and substructure preparation. Our expertise ensures stable bases for highways, sea defenses, and flood alleviation schemes. With in-house plant hire and skilled teams, we deliver efficient, compliant solutions for complex civil projects.
Exposed Aggregate Concrete
Specialists in exposed aggregate concrete (EAC), we provide durable, low-maintenance surfacing for promenades, footpaths, and commercial areas. Available in diverse aggregates and finishes, EAC combines aesthetic appeal with structural resilience. Our methods enable rapid installation, ideal for large-scale schemes like coastal defenses.
Fiber Reinforced Concrete Works
Our fiber-reinforced concrete (FRC) structures are engineered for strength and longevity in challenging conditions. Applications include foundations, retaining walls, and bridge components. The use of steel or synthetic fibers reduces cracking, ensuring high-performance outcomes for infrastructure projects across the UK.
Sea Defences
We design and construct robust sea defenses, including recurve wave walls and insitu revetments. With 15+ years of specialist experience, our solutions protect communities and infrastructure from coastal erosion. Projects span Colwyn Bay and South Shields, combining EAC and FRC for durability.
Plant Hire
Our plant hire division provides mini excavators up to 21-ton models, 360 wheeled excavators, and a Scania G450 crane for nationwide projects. Operated by CPCS-certified professionals, this equipment supports demolition, groundwork, and haulage services, ensuring efficient project execution.
