  • Integrated water-soluble film is dissolved in the rubber asphalt waterproof sheet to secure adhesive strength on freshly cast concrete on the adhesion side of waterproofing layer on the floor slab. In addition, in order to determine whether the water in the concrete slurry can dissolve the water-soluble film sufficiently, the adhesive strength of the waterproofing sheet was compared between difference wetness condition at the upper part of the concrete specimen before the concrete casting.

  • This study introduces and demonstrates the application of an experimental regime for anti-seismic performance evaluation of waterproofing materials to used for concrete pile walls. Concrete pile walls are subject to high degree of seismic load, and the occurring stress can affect the waterproofing integrity of the structure, but there is currently no existing methodology or standard for evaluating this property of waterproofing materials. To propose and conduct this evaluation, a new testing apparatus was designed and manufactured intended to be able to test an installed waterproofing material's seismic resistance performance.
