What materials are commonly used for a damp proof course?
Materials. Materials widely used for damp proofing include: Flexible materials like butyl rubber, hot bitumen (asphalt), plastic sheets, bituminous felts, sheets of lead, copper, etc. Semi-rigid materials like mastic asphalt.
Can I inject a damp proof course?
Damp Proof Treatment Using Injections If your property is suffering from rising damp, then any salt contaminated plaster will need removed before injecting a damp proof course. Plaster is usually removed to a height of no less than one metre to remove the salt affected plaster prior to injecting the chemical DPC.
Which chemical is used for DPC?
Protekta DPC is a low viscosity, highly penetrating silane, silanol -siloxane solution, which has been specifically formulated to permeate into wet / dry wall. Once impregnated into a course of brickwork, DPC reacts with minerals present to form a durable polymer damp course, which permanently stops rising damp.
What is the best damp-proof injection?

Which type of cement is used for damp proof course?
Damp proofing treatment to floors This layer is known as base course and its material is well rammed. A75 to 100 mm thick layer of lean cement concrete (1:3:6 or 1:4:8) mix or lime concrete is thereafter laid over the base course.
Which cement is best for DPC?
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.
Can you damp proof solid walls?
You can damp proof a solid stone wall. However, you will need to approach it differently to a modern cavity wall construction. You will also need to determine what is causing the damp in the first place.
Which type of cement is used in damp proof course?
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 the case of a damp and humid atmosphere, a richer mix of concrete should be used.

Can you inject DPC into brick?
For those using a DPC cream for the first time, it’s not to say you cannot inject into brick, but we advise to reduce the drill hole centres from 120mm apart to 100mm apart or two injected holes per brick face to assist sufficient transfusion of injection cream.
Which type of mortar should be used for damp proof course and cement concrete roads?
Explanation: For damp proof courses and cement concrete roads, cement mortar in the ratio 1:2 should be used.
When to use a damp proof injection course?
Damp proof injection is a fast, cost-efficient and highly effective form of rising damp treatment. It is commonly used as a remedial damp proof course on buildings where the existing DPC has failed due to age or deterioration.
What are the different types of damp proofing?
A Damp Proof Course, or DPC for short, is a barrier that stops damp from the ground rising up into a building. There are two main types of DPC: membrane damp proofing and chemical damp proofing.
Which is the best injection for rising damp?
Damp proof injection is a fast, cost-efficient and highly effective form of rising damp treatment.
What can damp injection be used for in masonry?
The solution then penetrates the masonry and creates a water repellent barrier. One of the key benefits of this type of damp proofing is that damp injection can be used in walls that have suffered from severe water saturation.
