Services
Concrete Ready-Mix
Our ready-mix concrete is produced at Drumahoe and Coleraine depots using high-quality basalt aggregates. This versatile material suits projects from small domestic builds to large-scale infrastructure. Delivered efficiently nationwide, it ensures consistent strength and durability for foundations, structures, and roadways.
Concrete Blocks
NSAI-certified concrete blocks offer exceptional strength for residential, commercial, and agricultural construction. Manufactured to strict quality standards, these blocks provide thermal insulation, fire resistance, and acoustic performance for walls and partitions.
Aggregates
Sourced from our own quarries, basalt aggregates enhance concrete durability and road construction longevity. Available in various grades for landscaping, drainage, and structural applications, they meet rigorous quality control specifications for permeability and strength.
Screed
Specialist screed mixtures provide smooth, level bases for commercial and residential flooring. Formulated for rapid drying and minimal shrinkage, our screeds support underfloor heating systems and heavy-duty industrial environments.
Mortar
Precision-blended mortar ensures strong, weather-resistant bonds for bricklaying and blockwork. Available in workable mixes for traditional and modern construction methods, it complies with British and European standards for structural integrity.
