Where does vertical DPC go?
The vertical DPC is inserted between the walls around the window to stop water travelling in from outside through the external wall from reaching the internal wall.
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.
How is damp proof course installed?
How to Install a Damp Proof Course
- Drill 12mm diameter holes at 115mm intervals in the mortar course (or via the brickwork, angled down to meet the mortar course) selected to be at least 150mm above outside or abutting ground level.
- Fit the extension nozzle to the cartridge tube and load into the skeleton gun.
What is the thickness of damp proof course?
40mm thickness
The DPC should be of 40mm thickness and should be of uniform thickness. It should not be provided at the locations of the door openings. The top level of DPC should match with the planned finished floor level.
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.
What is the difference between damp proof course and damp proof membrane?
A damp-proof course (DPC)is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission.
What is the best damp proof course?

Where does a damp proof course go?
The DPC in the inner wall is usually below floor level, (under a suspended timber floor structure), or, with a solid concrete floor, it is usually found immediately above the floor slab so that it can be linked to the DPM under the floor slab.
What can damp course injection be used for?
Damp course injection is used to treat rising damp. It forms a waterproof layer in your brick mortar, which will prevent the water from rising upwards and turning into damp. Damp proof coursing is a great DIY alternative to adding a standard DPC. It is often used in conjunction with other measures like applying a damp proof membrane to a wall.
How does a vertical damp proof course work?
Insulated vertical DPCs have a layer of polystyrene attached to them (see the image below – “An insulated vertical DPC”) which acts as an insulating barrier in the damp proof course around the window, preventing water from entering your internal wall and heat from leaving it. Insulated vertical damp proof course fixed in position
How does wall injection damp proofing work?
Also known as wall injection damp proofing, damp proof injection involves drilling a series of holes in the property and injecting the silicone-based damp proof cream. Once this cream has been injected, it diffuses rapidly before curing to form a replacement water-repellent DPC for the affected area.
Can a damp proof injection be carried out without a DPC?
A damp-proof injection to install a Damp Proof Course (DPC) in the walls of your building should only ever be carried out by a qualified professional. When a DPC has not been installed correctly, it is about as useful as not having one at all and the damage can result in the requirement of costly repair work.
