Polystyrene Decking Blocks

Simplify your construction with polystyrene decking blocks for rib and block concrete slabs. Lightweight yet durable, these blocks enhance structural efficiency, reduce weight, and improve insulation. Easy to install, they’re the ideal solution for faster, more cost-effective building projects.

Product Dimensions

All our polystyrene decking blocks are:

- 1200mm long
- 550mm wide on the top
- 500 wide on the bottom

We generally cut a 25mm lip for the block to sit on the lintels.

These blocks are supplied in a number of standard thickness that include:

- 110mm (20DV)
- 150mm (20DV)
- 190mm (X-Grade)
- 230mm (X-Grade)
- 285mm (X-Grade)

If you need a different size block then we can also cut this for you.

Manufacture & Delivery

We make and deliver this product locally in:

Johannesburg
Cape Town

Polystyrene Density

Depending on the thickness of the block, we use either a low density, medium density or high density.

Current Lead Times

Generally 3 to 5 working days excluding weekends and public holidays. If you need it faster, please let us know so we can assist.

Please be very clear about how you will be using the polystyrene so we can recommend the right density for that specific application.

 

Eg. Polystyrene ceilings, cavity wall insulation, concrete roof insulation, concrete floor insulation, polystyrene decking blocks, polystyrene void formers for raising slabs or creating a void in a concrete slab etc

We have different prices in the regions so this helps!

We are trying to establish estimated lead times here and the urgency of orders.
