Where do you inject damp proof course?

Injecting Damp Proofing Cream

• Drill 12mm diameter holes horizontally into the mortar joint 150mm above ground level – if this is not possible then flanking works must be introduced to stop bridging of the damp proof course.
• Inject the cream into the boreholes using a low pressure sprayer or cartridge gun.

How do you inject damp walls?

Inject a new chemical damp proof course along the base of the wall to stop rising damp. The cream is injected directly into 12mm holes drilled in a mortar bed at regular intervals, preferably at perp-end joints, for an effective damp course treatment.

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 do you install a damp proof course?

How to Install a Damp Proof Course

1. 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.
2. Fit the extension nozzle to the cartridge tube and load into the skeleton gun.

Does injected DPC work?

The question is, does it work? In theory the fluid soaks into the wall forming a horizontal barrier to block any damp from rising up. But in the vast majority of cases the DPCs are actually injected at far too high a level to protect floor timbers. Furthermore, injected DPCs don’t work at all in thick stone walls.

How do you damp proof internal walls?

An easy solution to cure damp on internal walls is to paint walls and ceilings with Dryzone Mould-Resistant Emulsion Paint. The paint damp-proofs internal walls against condensation and protects for at least 5 years from unwanted mould growth.

Can a damp proof course be done from outside?

Damp proofing can be done from outside of a building. In fact, in most cases it is the easiest way to damp proof a property. Whether the property has had damp for years or you have caught it early, damp proofing the outside is a great way of keeping the damp out.

Can I do my own damp proof course?

DIY Damp Proofing For Rising damp If tanking is recommended, then this may be a solution that is best performed by professional damp specialists. However, inserting a new damp proof course (DPC) can often be done by using an injectable DPC and can be done as a DIY project.
