Concrete Waffle Flooring Systems_


Firth Ribraft®_

Concrete waffle slabs such as the Firth Ribraft® System have become increasingly popular for residential and light commercial floor systems due to their speed of installation and superior structural strength.

The system uses polystyrene pods separated by plastic spacers that quickly secure reinforcing in position with minimal tying of steel required. The pods can easily be site cut allowing for simple installations of drains or modification where complex geometries are required.

Engco worked with Firth to enhance this system to cope with the loss of bearing requirements of TC2 & TC3 site conditions.

Product enhancement included the addition of steel fibre reinforcing and the development and testing of a relevellable jacking system, which has now been adopted as the standard solution for those sites by many Engineers.
