| COFFOR is a patented structural
stay-in-place formwork system to build load
bearing walls. COFFOR is composed of two filtering grids made
of rib lath reinforced by vertical stiffeners. The grids are connected
by articulated rebar loops that fold for cost effective transport.
The volume used by COFFOR is 7
times less than the equivalence in bricks, concrete blocks
or Insulated Concrete Formwork (ICF).
COFFOR is very light: less than 11kg/m2
(2.25 lb/sq ft). A standard panel 1.22m x 2.70m (4' x 9') weighs 35kg
(77lbs). COFFOR can easily be carried by 1 or 2 workers.
After COFFOR is placed, concrete is poured inside. Excess
water is eliminated by gravity through the grids. The fluid
concrete becomes semi-solid decreasing pressure against the grids.
This explains why COFFOR can be so light compared to traditional heavy
waterproof formworks.
COFFOR remains in the construction to
reinforce it after the concrete is poured. |
