Claygrain

Sodium bentonite powder for waterproofing and excavation works

Claygrain is a dissolved, anhydrous sodium bentonite powder, characterised by a montmorillonite content in excess of 95%, with low yield-point (proof). The product should be used as it is, to increase the amount of bentonite in punctual areas, or mixed with cement and water or just water to obtain a slightly expansive waterproofing mortar, suitable for smoothing any crawl spaces in the concrete prior to laying and refilling the Claytex bentonite sheet.
