CSI was asked to determine the integrity or condition of an asphalt layer that was designed to function as a water-proofing membrane between two concrete layers.
The object was for the building to be “revamped” and brought up to the standard of the current code.
CSI developed a methodology tailored specifically for this project that allowed the team to make a conclusion about the material properties of the top concrete layer by applying the laws of wave propagation.
CSI could prove that water ingress was apparent in the top concrete layer throughout numerous areas of the object. This allowed us to conclude that the asphalt layer was damaged and that it lost its waterproofing properties.
As a result, the main contractor could prove that the damage was not caused by their activities as CSI’s investigations were carried out ahead of the construction start. Furthermore, the successful outcome of the investigation meant that the contractor can communicate this to the principal client. Subsequently, appropriate measures could be planned for in the design stage of the project.
