Abstract: A waterproofing membrane system comprising a mixture of dry rubber granules with dry expansive material granules, the mixture adhered to a membrane in a layer. The rubber particles act to limit expansion of the expansive granules in each layer when the membrane is introduced to a source of moisture. Making an expansive sheet waterproofing system comprises determining a desired waterproofing and expansion need by mixing of the rubber granules with dry expansive granules and applying the mixture as a layer to a substrate having an adhesive coating thereon. The coating resulting in the rubber particles limiting expansion of the expansive granules when exposing the prepared membrane to a source of moisture. The membrane retains flexibility and waterproofing, durability and strength of the membrane is increased.
