Abstract: A water impermeable sealing apparatus. The apparatus includes a first sealing strip having a base that has a first set of fastener elements carried on its surface in two spaced-apart areas. Extending along the first surface of the base between the two areas of the first set of fastener elements, a first sealing element protrudes from the base. A complementary second sealing strip also includes a base with a second set of fastener elements on its surface in two spaced-apart areas. Extending along the surface of the base between the two areas of the second set of fastener elements, a second sealing element protrudes from the base for non-interlocking engagement of the first sealing element when the first and second fastener elements are engaged.
