When do i need silicon damp proofing injection cream carried out?

In a nut shell....when you have a rising damp problem. Rising damp occurs when ground water moves up a wall through small tubes in the bricks by capillary action (like a straw sucking up water). Most walls allow some water in, but it’s usually stopped from causing damage by a barrier called a damp proof course (DPC). If you don’t have a DPC or it has failed, then there is nothing to stop water rising up your wall. Rising damp can also occur when the ground level outside your home is higher than your damp-proof course, allowing water to bridge the damp proof course.

How we treat your problem using silicon injection

This DPC injection video shows how we inject damp-proofing silicon / cream to stop rising damp problems in masonry walls. The 100% active damp-proofing cream is introduced into a series of 12mm holes drilled into the bed-joint by means of a simple injection applicator. Once the cream is injected, it diffuses rapidly before curing to form a replacement water-repellent damp proof course for the effective repair treatment of damp brick / masonry walls. This is a specialised job, Top Joints are very experienced in this sector; we will carry out your works correctly, and efficiently.

Installed Kair Flat Ventilation System, “Work was carried out efficiently and neatly and clearly every effort had been made to clean up afterwards. The work took longer than scheduled - into second day - due to difficulty boring holes through re-inforced concrete (not anticipated) but this did not inconvenience me as flat is unoccupied at present. Allround a very friendly and helpful workforce. Very satisfied with outcome and would recommend this firm.”

Fixing a damp problem and re-plastering, “We had a damp problem in our hallway and a number of contractors looked and quoted for the work. Top Joints were the only company to properly look into what had caused the problem and did not automatically assume we had rising damp (old house, no DPC). It turns out a leaking stop cock was causing a localised problem, yet everyone else tried to sell us a DPC. Once the real problem had been identified, Top Joints' quote and plan of remedial action was very competitive and we were happy to give them the work. Everyone we dealt with was courteous and polite and queries were responded to quickly and professionally. I would recommend Top Joints.”

Kept informed of progress during the day. Quickly resolved small technical issue after installation. Would thoroughly recommend this company..”
