Article and method for sealing seams between water barrier articles

摘要: An article of manufacture including an elongate confined mass a water-swellable clay for sealing joints or seams between adjacent water-barrier materials plugging defects other unsealed areas to layer. The elongate, is manufactured in any desired cross-sectional shape configuration e.g. circular, eliptical, rectangular, square, and the like can be roll form dispensing individual masses individually. within layer material that permits entrance water contact hydration clay, such as by being water-porous water-soluble upon sufficient confining will dissolve sufficiently, burst tear permit relatively free movement hydrating expanding clay.
