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

Pleased with this product already used once before.

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!

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,

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.

When we found a patch of rising damp (just one small area, about 1.5m wide and 1m high), we realised something must have gone wonky with the damp course in that section of the wall. We used this as per the instructions, but used little plastic caps to keep the cream inside each of the drilled holes. After just under two weeks, the rising damp patch had visibly gone down hugely to virtually nothing, with nothing at all showing above the lines where this was inserted. It seems to have done the trick. Time will obviously be the true test, but if you have a damp issue and want to try something cost effective first this was super easy with the right tools (drill etc) and is worth a try.

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.

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

Aunque me costó preparar la pared para la aplicación del producto, una vez inyectado, esta realizando su función. Verificada su eficacia después de haber trascurrido tiempo y mucha lluvia. No tiene muchas densidad por lo que es recomendable aplicarlo poco a poco. No abarca la superficie que pone, es bastante inferior, por eso no le pongo 5 estrellas. Por lo demás todo bien. Si fuera más barato no me vendría mal. Recomendable.

Ottimo prodotto, dopo averlo applicato come scheda tecnica, il risultato è stato super, da tenere conto che i materiali per la rasatura devono essere traspiranti idem i fissativi e la tempera murale, sono passato da una umidità del muro del 25% a 5%, vedremo negli anni come andrà. Specifico! Non sono un professionista

Also nochmal.......feucht unne,,,bohre,,,,spritze rinne,,,,TROCKEN. Genial das zeug,,,,nach Anweisung.

Super einfach und hält was es verspricht.

SE hai dei veri problemi di umidità di risalita questo prodotto è del tutto inutile. L'avrò sparato tre volte dentro i muri ma il risultato è stato pari allo zero. Lasciate perdere questa non è la soluzione.
