Twin Wall
Using prefabricated panels comprising two slabs connected by means of castin lattice girders to form a single unit into which concrete is poured on site, Hanson's Twin Wall is a fully flexible walling system that combines the speed and quality of precast concrete with the structural and waterproof integrity of a continuously poured in situ concrete structure.
Without restriction on architectural layout, the system eliminates the need for expensive formwork and the waiting time for the removal of formwork to provide for fast build, with installation rates of up to 100m2 per hour.
No edge shutter is required when pouring upper floor concrete and plastering to ceiling is not necessary to achieve a high quality finish.
The panels are machine manufactured to exacting tolerances and can incorporate cast-in cable ducts, electrical boxes and service ports. They are supplied complete with floor, window, door and ventilation openings. Once installed, panels provide superior sound insulation.
By reducing weight, prefabricated Twin Wall panels provide savings in both transport and crane costs.
Full computer design with detailed installation drawing, calculation and method statement can be supplied for each project.
