Easy to drive in anchors! The perfect waterproofing material for ponds with vegetation.

Borklay Matt is a waterproofing material for civil engineering developed by Setco (USA), which boasts excellent bentonite production capabilities. It is used worldwide in applications such as waste final disposal sites, disaster prevention for oil tanks, and artificial ponds, earning a high level of reliability. This product is a "reinforced" GCL that sandwiches granular Na-type bentonite between woven and non-woven fabrics, fixed together by needle punching, and uses Na-type bentonite known for its quality and purity. 【Features】 - Since bentonite is a natural inorganic material, it is expected to have semi-permanent durability. - The quality of bentonite remains unchanged even after repeated wetting/drying and freezing/thawing. - It has durability sufficient to be used as a treatment material for high-level radioactive waste. - Even if pinholes or tears occur, it quickly self-repairs through bentonite swelling. - No skilled workers or special machinery are required.
