<p>A laminated waterstop strip used in the construction of buildings that is placed on the top of a surface of a hardened concrete layer of footing, prior to pouring of an additional layer, and is made to have a number of granular layers held with adhesive between each of the layers, and having in the range of 30 to 60 individual granular layers so that the waterstop has a height of in the range of one-half to one inch. The waterstop strip is made up of bentonite granules, preferably, which are adhered to a fabric layer for support, an adhered layer on the exterior of the fabric layer, with a quick release paper on the exterior of the fabric layer. A light weight, synthetic fiber mesh for providing weather resistance, tear resistance, and retention properties is placed over the upper layer of particles. The waterstop strip is made in a batch process before being cut into strips by utilizing a reciprocating multi-station adhesive and particle dispensing carriage that will move back and forth across a desired size sheet of fabric until the number of layers of particles and adhesives have been built to the desired level and the adhesive forms an elastomeric matrix to retain the particles together.</p> |
