Grout and crack injections work best when you can’t get to the leak,
but We can.
We complete a full circle of waterproofing by offering negative side protection. Stop active leaks below grade structures, against the positive side. Even with head pressure, we inject material from the back side or blind side and the leaks stop, FAST.
American River Caulking is certified to apply DE NEEF® Flex SLV PURe an ultra low viscosity hydrophobic polyurethane designed to be injected into hairline cracks in concrete structures. DE NEEF® Flex SLV PURe grout expands on contact with water and quickly cures to a tough, flexible foam that is resistant to most organic solvents, mild acids, alkali, petroleum and micro-organisms.
The advantages are clear. It has super low viscosity for hairline cracks and the free foam expands up to 18 times. It contains no volatile solvents, controlled reaction time and low temperature performance (Flex Cat PURe liquid to -40°F.)
Cut off large leaks with one injection. If you have questions, please call us at 530-878-4475 or email us.
