As mentioned in Foundation Waterproofing 101, water damage to a foundation can be very costly and difficult to repair. By paying close attention to how and where water might enter the foundation during the early stages of construction, typical failures can be avoided by following these simple guidelines…
For the Designer: Keys to proper installation
Design and Quality Assurance
- Don’t wait to design the foundation waterproofing system after you’re already in the ground!
- Specify and detail the appropriate system for each project. Meet with manufacturer reps early!
- Require shop drawings and kickoff meetings to ensure the entire team understands the importance of the design! Review examples of common failures.
- Get your consultants on board early: Geotechnical engineer, Structural engineer, Waterproofing/enclosure consultant.
- Review warranties, require third party inspections, installer certification, and contractor training.
For the Installer: Keys to proper installation
- Provide smooth continuous surfaces to install waterproofing – minimize jogs, protrusions, and sharp edges.
- At slabs: compacted fill/rigid insulation board/rat slabs
- At walls: fill bugholes, remove/grind concrete fins, mortar snots, fill form tie holes, verify form release agents and compatibility.
