A destructive investigation identified several sources of moisture infiltration which were contributing to increased moisture levels beneath the existing concrete floor slab of this facility.

The contributing sources were grading around the building was directing water towards the building, defects in the masonry veneer wall system was allowing water to collect in the wall cavity and lack of below grade waterproofing was allowing water to flow through foundations and beneath the floor slab.

The scope of work that our team designed and installed included replacement of the through-wall flashing system in the exterior masonry walls, the installation of a trench drain system at the base of the building, the installation of additional catch basins and modifying the grade towards our new drainage features and away from the building.
