DINCEL CONSTRUCTION SYSTEM is based on an internationally patented, lightweight, hollow form, manufactured from a durable rigid polymer, which when filled with ready mixed concrete, produces a load bearing, fire resistant structural element. The forms are easily connected by hand via patented, ‘snap together’ joints and can be utilised for walls of any length at the rate of three forms per lineal metre. The forms are cut to specified length in the factory and can be utilised in walls and columns of any height, without the need for cranes or other lifting equipment. Walls and columns built using DINCEL CONSTRUCTION SYSTEM can be constructed for lower cost in less time than by traditional masonry and concrete and are straighter, safer, more durable and require fewer, lower skilled workers. The system produces a non-brittle, water proof structure for internal and external walls in all types of residential, commercial and industrial buildings. It results in high strength elements with fire, insulation and acoustic capabilities of the highest rating, for a wide range of long lasting, maintenance-free buildings, and water, crop and material storage structures. BASEMENT CONSTRUCTION AND WATERPROOF WALLS are now available.
