Does Waterstop-RX have to be replaced if it rains prior to the concrete placement?
Typically, Waterstop-RX does not need to be replaced if the product is exposed to water for a short time period prior to concrete placement. If it rains, standing water should be removed as soon as possible and the product should not be left submerged in the water. As long as there is no notable expansion of the product, Waterstop-RX would not need to be replaced.
