PVC Waterstop Weld Testing: Assuring Joint Integrity Before You Pour
Stop Leaks at the Source — Before Concrete Is Placed
PVC waterstops are a critical line of defence against water travelling through construction and movement joints. However, every welded intersection or lap is a potential weak point if not properly fused. Our PVC Waterstop Weld Testing service uses a calibrated high‑voltage spark tester to identify pinholes, voids, and incomplete fusion before the waterstop is encased in concrete.
How It Works
A specialised spark tester is passed along the welded connection while the waterstop is electrically isolated. Intact PVC acts as an insulator. Any defect allows the test voltage to jump, immediately alerting the technician and pinpointing the fault. The weld can then be re‑worked and re‑tested on the spot, ensuring a continuous, watertight barrier.
Why Builders and Asset Owners Rely on This Test
Confirms that all welded joints are fully fused prior to concrete placement
Reduces the risk of joint leakage into basements, lift pits, tanks, and podiums
Avoids costly post‑construction investigations, injections, and remedial works
Provides documented quality assurance for consultants, certifiers, and insurers
Ensure every waterstop joint is doing its job from day one — engage Waterproofing Integrity to perform PVC Waterstop Weld Testing before you pour.

Why Independence Is Everything
No product affiliations
We don’t sell membranes, coatings, or systems. Our advice is based on what’s right for your project, not what earns us a commission.
No contractor relationships
We don’t install and we don’t subcontract to installers. When we inspect or test, there is no commercial pressure to approve.
No conflicts of interest
When our report says a membrane has failed, it’s because the data says so. Our NATA accreditation means our testing has legal standing.
