The Rock-Face Block is made with the main block section being cast in BST Lightweight Concrete (half the weight of normal concrete - yet still retaining normal concrete block strengths). The "Fascia" of the block is permanently bonded to the backing block and cured.
TECHNICAL DATA:
- Compressive Strength - 10 MPa (average)*
- Density - 1250 kg/m3 (250 kg/m2).
- Dimensional Accuracy - +/-2mm
*Strength tests at NATA - Certified facility, in accordance with AS2733 (1984, Appdx. E).
