Dryzone Damp Proofing Cream Kit (Pack of 5 DPC Injection + Cox Mastic Gun & Drill Bit) High-Strength, BBA & WTA Approved Rising Damp Treatment.

Used this on a solid wall in a very old house (1600’s) - used the cream rather than the sticks. Easy to use and results noticeable within a couple of days . Used internally so coated wall below treatment with dry zones’ dry base paint - everything is now completely dry to the touch and my damp meter readings show a big reduction - it will take time for the wall to fully dry, but it is heading in the right direction and the very wet section at the bottom is now dry to the touch. Highly recommend.

Seems ok, quite messy to use. Time will tell if it works

it was put in with ease, theres almost no resistance when injecting it so go slow and pull out slowly as squeezing the trigger or there will be great wastage.

Good stuff easy to use

Highly recommend good value for money

I have a 1903 terrace house with cavity wall construction. The back yard slopes towards the rear wall and water channels along the building line before draining away. It is fair to say the the bottom two courses of brick are completely saturated as can be observed by moss growing and darker brick and wet joints. I used this product and can say it is brilliant. Within 2 days, following the bricks being saturated and experiencing rising damp for years, the mortar gaps have changed colour and the masonry is visually dryer! I followed the methodology and drilled and filled the mortar courses between the staggered bonds and also went as far as to also fill the bricks as they are also extremely pourus with high sorptivity. Fantastic product and I look forward to see it develop and dry our further. Great DIY product, with just the need of a decent drill. One thing I can say is be mindful if you pull the trigger too hard whilst drawing the tube back out of the wall, I experienced high pressure and the pipe shot out of the applicator with a great splatter. Great value compared to having a professional come in and do it, I would recommend this product to anyone as a remedial fix without having to replace a course of bricks and lay a new DPC!

It was easy enough to use. But after back filling 4 holes the tube was empty ! Have ordered another 5 tubes just to do a 5metre length of double brick ,1 metre was chimney breast, so was only 1 brick thick !! On old brick with soft mortar you seem to need a lot more.

Clear instructions easy to use and product goes a long way
