Installation

RMAX VoidForm® Waffle Raft Slab System Components

Voidlock (SPACER) Voidform Located Together

Installation

Step 1 - The building site must be levelled., all plumbing pipes fixed in place and the formwork positioned. Step 2- Plastic sheeting of 200 microns is spread over the site, with all laps taped. Step 3 - Starting from the corner of the site, lay VoidForms in grid pattern, using Void-Lock grid spacers. The VoidForms can be easily cut to size and to fit plumbing fixtures. Step 4 - Place the reinforcemer bars between the VoidForms and the top mesh over the total area. Ensure tie laps are used as required. Step 5 - Place chairs under the mesh at a rate of 4 per VoidForm. Step 6 - In a single concrete pour, partially cover the VoidForm before filling the ribs. (This will help prevent the VoidForm from floating)
