KINJOYA FM VERDASYS
Root-resistant Elastomer Modified Asphalt Waterproofing

KINJOYA FM VERDASYS is made with high-quality asphalt as the base material, modified with styrene-butadiene-styrene (SBS) thermoplastic elastomer rubber, and uses imported chemical root inhibitors. It is specially formulated into a polymer root-puncture-resistant modified asphalt material. With polyester felt or polyester felt composite copper foil as the base, it is made into a rollable root-proof waterproof material. It causes plant roots to automatically change direction and continue growing at a distance of 20mm from the waterproof membrane, making it impossible for roots to penetrate the waterproof layer, ensuring both plant growth and waterproof effectiveness.
