Abstract: A method, apparatus and system for testing the self-sealing properties of a concrete sample. The method may include providing an apparatus for creating a consistent and reproducible crack in a concrete sample and creating a consistent and reproducible crack in the concrete sample with the apparatus. The method may further include providing a fluidic delivery system that provides a consistent flow of fluid for testing the self-sealing properties of the concrete sample and testing the self-sealing properties of the concrete sample with the system.

Abstract: A method and system for constructing a concrete waterstop joint between first and second concrete portions. The method may include applying a continuous longitudinal cementitious and reactive waterproofing grout strip to a joint area of the first concrete portion and then forming the second concrete portion over the grout strip. The system may include a first concrete portion having a joint area, a continuous cementitious and reactive waterproofing longitudinal grout strip connectable to the joint area, and a second concrete portion formable over the grout strip. There is also provided a use of a cementitious and reactive waterproofing grout strip in the construction of a concrete waterstop joint between first and second concrete portions.
