    SikaProof®-730 PA (formerly known as MasterSeal® 730PA) - Pre-applied waterproofing membrane for below grade waterproofing 


    MasterSeal 730PA is a tough HDPE membrane treated with a unique Pressure Sensitive Adhesive to enable good adhesion with freshly poured concrete surfaces and has a Dual Lap Seal, having adhesive on both side of overlaps for dual adhesive lap sealing seam. The pressure sensitive adhesive matrix offers weather resistance during the casting process.
