Waterproofing Inspection
An independent waterproofing inspection survey of the installation of waterproof membranes is critical as Human errors in application can often prove devastating for both basements, roof decks, blue, green & flat roofs.

Methods Of Testing
A variety of testing methods can be used in a Waterproofing Survey. As accuracy is paramount, methods are agreed at pre-verification/inspection stage though any GeoShield Quality Assurance Program can be enhanced as need requires. Our selected methods of testing are:
- Visual
- Mechanical point stress test (Pick and probe)
- Air Lancing following ASTM D4437 / D4437M - 16 (2018
- Pressure testing twin wedge welding joint
- Dielectric porosity testing
- Smoke test
- Inert gas test
- Weld testing using tabs (destructive test using 'mole' grips)
- Vacuum testing box
- Ultrasonic pulse echo testing
- Podium & Bund Lining Flood Tests
- Trench Lining Flood Testing
- Drone Surveys
- Surface Regularity Testing
- Surface Anti-Slip Testing
- Waterproofing test
- GCL testing
- Bentonite Membrane testing
- Waterproof Membrane testing
- Spark testing
- Green Roof testing
- Blue Roof testing
- Podium Deck testing
- Real time waterproof monitoring
Independent verification of the installation of waterproof membranes and lining systems on site is critical to achieving the performance required & avoid failure. Human errors in application can often prove devastating for both basements and roof decks. This is acknowledged by British Standards. Areas needing specific attention include Blue & Green Roofs where either a body of water or soil retaining water is a permanent feature which if compromised could have disabling consequences for the structure below and the mechanical operations employed within.
GeoShield offer, across the globe, comprehensive Waterproofing Surveys & Lining Inspection programs that cover all aspects of design, application, training, monitoring, recording & reporting that will unquestionably reduce the element of human error.
The GeoShield on-site Waterproofing QAP program is operational from the initial concept to the buildings completion. GeoShields team of inspectors are all Certified Surveyors of Structural Waterproofing, the team will control the validation procedure and perform all required inspections & testing in a process of Observation / Recording & Reporting.
The frequency and nature of inspections & tests are bespoke to each project and relate to the intricacy of design, level of risk & competency of the application operatives. On a building completion a Verification and Validation report is created for submission to the clients O-M manual containing, site testing and inspection survey documents, photographs and other applicable records. The GeoShield Waterproofing & Lining Application Inspection Program provides:
- Open conceptual discussion, realising the possibilities available and what is desired / expected by the Client / Designer.
- Site investigations & surveys at the earliest stages & on-going.
- Independent soil & water tests for product suitability.
- Assistance with Project Specific Designs.
- Project Specific Specifications.
- Mandatory Pre-Construction meetings attended by all the construction team
- GeoShield to provide electronic reports & distribute to site.
- The chosen applicator company to receive Approved Applicator status via GeoShield Ltd.
- Designated GeoShield Team CSSW (Certified Surveyors in Structural Waterproofing) Qualified Inspectors
- All recognised discrepancies & deficiencies in the projects work are corrected with immediate effect.
- On going post-construction meetings to review the waterproofing systems performance and evaluate for improvement.
- GeoShield are members of the Property Care Association
