Used for the prevention of aggressive infiltration. Wherever high-water flow needs to be stopped, you can be well prepared to stop leaks easily and permanently, with our SealGuard II Starter Kit at a fraction of the cost of traditional methods.

SealGuard II is a dual component, highly reactive, early strength, hydrophobic polyurethane grout, used to control high flowing water leaks within seconds either in manholes, culverts, bunds, or any brick or concrete structure. It has a simple installation process, and a small and patented application equipment which allows reuse of cartridges.

SealGuard II It is extremely fast-acting – it stops fast flowing leaks within 1 to 3 seconds! Performing well with all but the most severe solvent or chemical attacks, such as highly concentrated nitric or sulphuric acid. SealGuard II is hydrophobic — it will not shrink, transmit VOCs or require special breathing systems or protection.

The SealGuard range of polyurethane grouts has been used in mines, geothermal wells, dry-docks, and virtually anything else that can leak. Highly visible water sealing projects, include:

• The “Big Dig” in Boston
• Ground Zero in New York City
• Dulles Airport in Washington, D.C
