Crack Injection Balloon
Provides a visual aid to the process of filling the crack. It stays inflated when the crack is full.
Allows accurate placement of the balloon. Allows you to see the crack and also lets you see the resin when it rises to the balloon. The base is designed to prevent adhesive blocking the aperture during placement.
Balloons out to 20mm (to keep the injection system pressurised).
Ensures secure closure of the balloon after inflation and allows leakage free connection to a injection gun. Also allows taps further along the crack to be left open if desired.
