Test Plugs

Say goodbye to costly inflatable and mechanical test plugs when conducting waterproof membrane testing.

Test plugs take away the stress of untested waterproofing. With WONDERCAPS's Test Plugs you can test all jobs and allow the onsite manager to confirm for themselves.

Each puddle flanged product has a matching color-coded test plug, ensuring you receive the correct plug for your specific product. No more losing test plugs down the drain or having to return to the site to replace missing, expensive plugs. Our lightweight, reusable test plugs are available today for that added convenience.
