About the Technology

This patented Structural Stay in Place Steel Formwork System is known as ‘Coffor’ to build load bearing monolithic concrete wall structures based on shear wall concept. The formwork system comprises of two filtering grids made of rib mesh reinforced by ‘C’ channel vertical stiffeners. The grids are connected by rebar which act as horizontal stiffeners and connector which act as a shear link. The grids on both faces act as sacrificial formwork in which concrete is poured in-situ.

After the erection of formwork panels in alignment, corners, edges of doors and windows frame are closed with rebar positioning & concrete of required grade is poured in the panels. The concreting is done with a pump, bucket or with a shovel loader. The inside and outside walls are finished with cement plaster of suitable grade.
The panels are prefabricated according to a structural plan (based on architectural plans) designed by structural engineers.
