Our Clients Say

I can only say this product is everything it promises and more. Highly recommended. Brilliant service. Thank you

I bought 5 buckets of DAMFIX Wet for my dam. Application was easy. Seepage through the wall gradually stopped over about 3 weeks. I'm happy with the product!

I Used DAMFIX WET in my dam 3 months ago, and it seems to be holding the water levels quite well. With the recent rainfall, it's the first time I have ever seen water flowing over the spill way!💙 Good product indeed👌🏼

I wasn’t expecting much when I first tried DamFix Wet, but it completely exceeded every expectation I had. This stuff WORKS! The application was quick and far easier than I expected. Within a few days I could already see a noticeable difference. This product sealed my dam! DamFix is absolutely worth it. I’ll definitely be buying more for my second dam. Highly recommended!

All i can say is DAMFIX works!!!! We had a huge leak in one of our earth dams We did the application and within 36hours the water has completely stopped seeping through. Great product! Thanks to the Damfix crowd

We had a serious dam wall leak at our mining site in Brits, but couldn’t drain the dam due to operations. DAMFIX Wet™ was applied using an adapted soil-mixing method, and the team achieved an estimated 80% seal in about five days using eight 20L buckets, without stopping production. The product worked into the soil and sealed the leak without needing to drain the dam. Over time, the previously saturated bank dried out completely and the seepage stopped. Even a year later, the repair is still holding and the area remains dry, with vegetation still intact. It was a simple application and made a noticeable difference very quickly.

We had a leaking section on our earth dam that was causing serious water loss and a very wet embankment area. After applying DAMFIX Wet™, the problem area was treated using only two 22-litre drums. The product worked into the soil and sealed the leak without needing to drain the dam. Over time, the previously saturated bank dried out completely and the seepage stopped. Even a year later, the repair is still holding and the area remains dry, with vegetation still intact. It was a simple application and made a noticeable difference very quickly.

DAMFIX Wet™ is a polymer-based granular solution that is applied directly to the surface of a leaking dam. When it comes into contact with water, it activates and swells significantly. It sinks to the floor of the dam. With hydrostatic water pressure the expanded material moves into porous areas, where it bonds with soil particles to create a natural seal — without needing to drain the dam.

No. DAMFIX Wet™ is specifically designed to seal leaking dams without draining the water, saving time, reducing costs, and avoiding unnecessary water loss.DAMFIX Dry™ is designed for new dams or empty dams where soil compaction can be properly done during construction. This sealing process accelerates the settlement period of the dam.
