Profile: Collier and Henry Concrete (Floors) Ltd. is a supplier of concrete products. Our product line includes TeTRIS & U-Base, Q-Life flooring system, N150T and N215T series. Our CHC Tetris® flooring system increases the floor thermal efficiency, and eliminates cold bridging by enabling the builders to comply with the demanding requirements. The Tetris® insulation blocks work in conjunction with pre-stressed concrete floor beams to form a fixed floor level. The Tetris® insulation blocks are strong and robust and made from lightweight, closed-cell, high compressive strength extruded polystyrene material. Our CHC U-Base flooring system utilizes expanded polystyrene insulation panels to form the main insulant for the finished floor. They also provide the temporary form work on which to lay the structural screed. We offer a full service from conceptual advice to design, manufacture, delivery, and installation. We also provide a fast, accurate, and competitive estimating service for all flooring needs.
