This equipment is used to provide a chemical damp-proof course in brick or stone walls to eliminate rising damp. We stock the DPC chemicals that are injected directly into the mortar bed at low pressure (see technical section for more information).
25ltr drums of solution sold separately in store on a sale or return basis and are not included in the price.

General Guideline
1. Whenever possible work below floor level (suspended wooden floors) internally and above ground level externally.
2. Strip skirting boards and plaster from internal surfaces, to a height of 1m (39ins) above intended DPC level.
3. Drill 10mm holes directly into mortar bed 150mm (6ins) spacing. Whenever possible work from both sides of a cavity wall otherwise drill through and inject from the outside. (Solvent based DPC's are normally injected into the brick or down through the brick into the mortar bed.)
4. Inject the silicon fluid until it spreads evenly across the bed and 'bleeds'.
5. Plug holes with mortar or plastic plugs. Allow to dry thoroughly before replastering and making good.
