Polymer concrete is produced by mixing mineral aggregates with resin binding agent.
Resulting high quality enclosure is smooth surfaced. The pits are lightweight and easy to handle ensuring cost effective installation. Although having thinner side walls, properly designed polymer concrete cable pits are strong, durable and possess mechanical properties typical of bulkier concrete enclosures. They can be cut with masonry drills and grinders.
Polymer concrete pits provide excellent electrical insulation because castings are homogenous (no steel reinforcing) and no macroscopic voids (moisture traps).
The material is non porous and offers a much higher resistance to chemical, weathering and biological attack than concrete, ensuring pits have superior life cycle.
