The mix of DPC (Damp Proof Course) is typically a cement concrete mix of 1:2:4 (1-cement : 2-coarse sand : 4-12.5mm stone aggregate), combined with a good quality waterproofing compound.
Here's a breakdown:
- Cement: Provides the binding properties.
- Coarse Sand: Acts as a fine aggregate, filling voids.
- 12.5mm Stone Aggregate: Provides bulk and strength to the concrete.
- Waterproofing Compound: Enhances the water resistance of the DPC, preventing moisture penetration. The compound should be mixed according to the manufacturer's instructions.
The DPC should have a uniform thickness, commonly around 40mm. This ensures consistent performance in preventing rising damp.
