Frequently Asked Questions
What do I inject into a leaking crack?
A hydro-reactive polyurethane foam such as Mountain Grout Gel or Flexible. Water triggers the foam, so it expands inside the crack and seals against pressure.
Which resin restores structural strength?
Ardex RA 142 low-viscosity structural epoxy. Inject it into dry cracks to weld the section back into one piece. Stop water flow first if the crack leaks.
What packers suit hammer-in fixing?
Brass hammer-in packers. Drill the port hole, tap the packer in, connect the injection gun, and cap or snap off after injection. Flush the port lines so resin reaches the full depth of the crack.
Low pressure or high pressure for basement cracks?
Low pressure with syringes suits fine structural cracks in sound concrete. High-pressure gun injection with gel foam stops gushing leaks in basements and tanks.
Do I need surface ports or packers?
Syringe ports for low-viscosity epoxy in hairline cracks; mechanical packers for foam injection against water pressure. Flush the port lines so resin reaches the full depth of the crack.
