Volclay

Volclay® waterproofing products offer total solution waterproofing. 

With Volclay's single source capability, you can be sure of a totally integrated waterproofing system that yields ultimate performance.   Each product uses the natural swelling and self-healing properties of Volclay®sodium bentonite.   This unique mineral was formed from volcanic ash and saltwater millions of years ago, making Volclay® products the most environmentally sensitive on the market today.  

All contain zero VOC, can be installed in almost any weather condition to green concrete, and most importantly, have proven effective for more than 30 years.
