    • Disclosed is a waterproofing membrane that bonds to concrete cast against it (i.e., post-cast concrete). The membrane includes a flexible carrier sheet, a pressure sensitive adhesive and reflective particles on the surface of the adhesive. The reflective particles should have an average diameter equal to or greater than the thickness of the pressure sensitive adhesive. Preferably, the reflective particles are ground white cement, ground hydrated white cement, ground partially-hydrated white cement or a mixture of two or more of these. The membrane does not have a removable release sheet that is typically used to prevent the adhesive portion of the membrane from adhering to the carrier sheet or other portion of the membrane when the membrane is rolled up.
    • 公开了一种防水膜,其结合到其上浇注的混凝土(即后浇注混凝土)。 膜包括柔性载体片,压敏粘合剂和粘合剂表面上的反射颗粒。 反射颗粒的平均直径应等于或大于压敏粘合剂的厚度。 优选地,反射性颗粒是研磨的白色水泥,磨碎的水合白水泥,磨碎的部分水合的白色水泥或它们中的两种或更多种的混合物。 膜不具有通常用于防止膜卷起时膜的粘合部分粘附到载体片或膜的其它部分的可移除的剥离片。
