Polystyrene Rib And Block Design Sizes & Dimension Details:

---

• All our polystyrene rib and block slab blocks are 1200mm long in dimension and vary in thickness based on your engineer's rib and block design & specification.
• Below you will see all our polystyrene rib and block thicknesses and recommended thicknesses based on the concrete slab thickness.
• If you need specific custom-cut polystyrene rib and block slab sizes and dimensions please let us know.

Estimated PolySlab Thicknesses Based On Concrete Slab Thicknesses

---

• Concrete slabs have to be designed and inspected by qualified engineers to ensure that the design loads of the slab meet the design of the concrete slabs.
• Consult with your engineers to determine if these blocks are suitable based on your slab design and slab loading requirements.
• Your engineer will specify the thickness of the blocks required.
• We will not supply PolySlabs to consumers unless they provide proof that an engineer has done a proper design.

Final Concrete Slab Thickness	PolySlab Block Thickness
170mm	110mm
200mm	150mm
255mm	190mm
300mm	230mm
340mm	285mm

PolySlab Design Properties

---

• Your engineer can use these properties to finalise your concrete slab design.

Density	Compressive Strength	Cross-Breaking Strength
X-Grade	60 kPa @ 10% compression	80 kPa @ 1% compression
20DV	110 kPa @ 10% compression	150 kPa @ 1% compression

PolySlab - Rib & Block Void Former Or Decking Blocks

---

• PolySlab Blocks are expanded polystyrene decking blocks or void formers used in rib & block slab construction.
• PolySlab Blocks are used instead of traditional ash blocks and they are placed between the concrete lintels to create a base on which the final concrete slab can be cast.

Benefits of using PolySlab Blocks instead of Ash Blocks

---

• PolySlab Blocks are lightweight and easy to lift in multi-story building projects.
• They significantly reduce they final weight of the concrete slab.
• They increase the rate at which concrete slabs can be prepared and constructed.
• Lightweight slabs reduce the amount of jacking supports required and the time that such supports need to remain in place.
• This means that work can resume faster during the curing period of the concrete slab.
• They increase the thermal and acoustic properties of the concrete slab.
