Concrete is the most widely used construction material in the world, composed of Portland cement and other cementitious materials such as fly ash and slag cements, crushed rock or gravel, sand and water. Chemical admixtures and other materials are often added to the mix to enhance the performance characteristics. It is commonly reinforced with steel rods (rebar) or wire screening (mesh).
We are equipped to carry out core cutting on bituminous materials, and lean mix, pavement quality and structural concrete. We have the capability to accurately identify the position of reinforcing within concrete structures in order to avoid it during core cutting, if possible.
In the field of civil engineering, nearly all projects are built onto, or into, the ground. Unlike other materials, which are subjected to strict controls during manufacture or processing, soil is usually used in the natural condition. Whether the project is a structure, a roadway, a tunnel, or a bridge, the properties of the soil at that location are of great importance to the civil engineer
Aggregate is defined as a granular material used in construction, which may be natural, manufactured or re-cycled. Natural Aggregates: Naturally occurring materials of rock or sand and gravel. These are extracted directly from land or marine sources for use in construction. Manufactured Aggregate: Aggregate of mineral origin resulting from an industrial process involving thermal or other modification
Bituminous road surfacing materials are produced by mixing mineral aggregate with a bitumen binder in predetermined quantities and within defined temperature ranges. Other materials are sometimes added to the mixture, including fibres, polymers and pigments to produce specific performance characteristics.
Aggregate is defined as a granular material used in construction, which may be natural, manufactured or re-cycled. Recycled Aggregates: Aggregate resulting from the processing of inorganic material, previously used in construction.
