TUFF- POD InstallationSTAGE 1 Clear and level the site. A footprint of the building site can be outlined and a layer of fines spread over the area. Construct and erect the boxing and lay the damp proof membrane over the fines. Plumbing and services go in at this stage. STAGE 2 The site is now ready for placement of Expol Polystyrene TUFF PODS, in conjunction with the Expol universal spacer. Pods are placed 300mm in from the perimeter boxing and 100mm apart over the floor area, or as recommended in the engineers schedule. Reinforcing steel is layed around the perimeter and between the pods. Steel mesh is then layed over the pods using bar stools where necessary. STAGE 3 The site is now ready for the pouring of concrete, which can be pumped or barrowed. The concrete should bevibrated andscreeded as per normal practice and adequate curing time should be allowed. Remove the boxing after curing.

Calculation for number of Spacers needed |
![]() ![]() |
| under | 100 Tuff-Pods | = | number x 2 | + | 20 spacers needed |
| over | 100 Tuff-Pods | = | number x 2 | spacers needed |
Note: It is important to refer to your engineers report/schedule. This information is a guideline only.
