The CKS polymer-modified asphalt root-puncture resistant waterproof membrane is made by adding styrene-butadiene-styrene (SBS) and rubber as modifiers, using high-quality chemical root inhibitors, and formulated through a special process. This elastic-modified asphalt polyester base membrane is reinforced with an intermediate reinforcing layer and covered with a polyethylene (PE) film or mineral granules, among other surface materials.
