WATERPROOFING MEMBRANE MANUFACTURER
Delivery News: Damp Proof Course has sent.

What is DPC?
Damp proof course (DPC) is generally applied at basement levels which restricts the movement of moisture through walls and floors. Selection of materials for damp proof course and its various methods of applications in buildings is discussed.
Properties of Materials for DPC
Be strong and durable and be capable of withstanding both dead as well as live loads without damage.
Be dimensionally stable.
Be free from deliquescent salts like sulphates, chlorides and nitrates
Pay attention to the application: DPC above ground level
For DPC above ground level with wall thickness generally not exceeding 40 cm, any one of the type of materials mentioned above may be used. Cement concrete is however commonly adopted material for DPC at plinth level, 38 to 50mm thick layer of cement concrete M15 (1:2:4 mix) serves the purpose under normal conditions.
In case of damp and humid atmosphere, richer mix of concrete should be used. The concrete is further made dense by adding water proofing materials like Pudlo, Impermo, Waterlock etc. in its ingredients during the process of mixing. It is used to apply two coats of hot bitumen over the third surface of the concrete DPC.
