Dryzone Damp Proofing Cream (DPC) - 310ml - High-strength Injection cream for rising damp treatment. BBA & WTA Approved

Dryzone damp proof cream is IMO the best damp proofer of its kind on the market. The wall in question had a serious issue and the amazing product fixed it completely.

Worked wonders. Stopped damping from happening. Great product, slightly pricey but worth it.

Have used this cream before. It is easy to use once the hole is drilled which is hard going DIY in a stone wall I worked on. A mortar joint in a brick wall would be easier. In a thick rubble stone wall you will need much more than you think due to voids in the rubble heart. There is no guarantee of effectiveness it will work in a rubble wall due to the way they are built but you have to see and maybe put more in later if no improvement. no smell,

Highly recommend this product. I use it all the time and get no comebacks.

Be very careful how you use this product, it's to easy to use too much. I asked my sister to inject my damp wall, and what should have covered 1.7 metres, only did 50mm. Instructions are worse than useless on the packaging, and website, but I think you are meant to withdraw the tube as you gently squeeze. Lesson learned.

Used on a single skin garage wall, where the existing DPC was either below or at path level, and rising damp, efflorescence & rainwater penetration to the internal slab were the problem. Dropping the paths was inadvisable due to shallow foundations to garage wall and potential water run off issues. Very easy to use the cream, hammer drilling 12mm dia holes to 2/3rd depth of brickwork, lining up with perp joints and mid-stretcher position, injecting in with a long frame gun. The only problem was gauging the amount going into the holes, making it easy to overfill & not leave enough space for the mortar ‘capping’ on the outside. The waterproofing effect was almost instant. A particularly persistent area of rainwater penetration to the garage floor slab cleared up after only a couple of days, and hasn’t returned about 3 months after I did the job. The chemical did leave a bit of a slight ‘water mark’ on the bricks, but that seemed to clear up after light wire brushing. The product is a tad expensive, and the coverage is slightly less than expected, but overall I found it to be a v.good solution to my damp issues. Cheers to Dryzone for a nice bit of their creamy best!

Works well, needed fast, hence Amazon. But it is pricey.

Easy to use cream fits my Skeleton Gun OK Time will tell about its effectiveness !
