Parkade Waterproofing and Crack Repairs

Waterproofing systems and membranes play an important role in the structural integrity of the substructure and the building itself. The membrane is the part of the building envelope that protects the concrete substructure from water ingress, which leads to structural failure over time. Improper installation or design can accelerate deterioration of these components.

Although the underground parkades and membranes are part of our standard building envelope condition assessments (BECA), we offer an investigation that concentrates specifically on their performance.

Our underground parkade condition assessment investigates the performance of the building envelope components that are responsible for waterproofing the foundation of the building and identifies all defects and deficiencies. Our assessments consist of residential questionnaires, detailed review of building plans and maintenance records, and an inspection involving detailed and invasive testing. Typically, an investigation will include non-invasive testing of the waterproofing membrane, sloping, water flow and water accumulation analysis throughout the property, quantification of the slab on grade settlement, identification of efflorescence, spalling and cracking of the concrete that may have been a result of water ingress as well as reviewing the performance of storm water sump pumps and catch basins. Our reports present the condition of different assemblies, findings of the investigation and recommendations for remedial solutions.

Upon the analysis of our investigation, we present our recommendations to clients in an easy to understand fashion, allowing the parties to collaborate in choosing a solution. Strata Engineering stands by our principles of transparency, efficiency and professionalism, and this shows through our Parkade & Membrane investigations.
