Good stuff easy to use

great product, everything you need included

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.

This is an excellent product but you need to follow the instructions carefully and use some common sense. To avoid wastage don't overfill the holes and use plastic plugs to seal them once full. It's important to follow the recommended hole placing and by doing so the wall begins to dry out within a few days. It's not cheap but used properly far better value than many so called expert damp proofing companies. To ensure the hole is completely full push the filler tube all the way in & whilst apply light pressure on the gun trigger slowly withdraw the gun & tube. Once the hole is full push the plastic plug in immediately. I've now treated three sections of wall in my 19th century house & Dryzone has done the job perfectly. Highly recommended.

Clear instructions easy to use and product goes a long way
