SikaFix HH+ Hydrophobic Polyurethane Grout – 5 Gallon Pail

SikaFix HH+ is a one-component, hydrophobic polyurethane chemical grout formulated to stop water infiltration in concrete cracks and voids—even under high water pressure. When combined with SikaFix Accelerator, the material expands rapidly, sealing off joints, cracks, and voids with minimal water needed to activate. Its low viscosity and ability to expand up to 30 times its volume make it highly effective for curtain wall grouting and crack injection. This non-toxic, 100% solids system bonds aggressively to concrete and remains stable in wet environments.

Key Features:

Hydrophobic polyurethane expands up to 30x its liquid volume
Seals actively leaking cracks and joints—even under high pressure
Requires minimal water for activation
Non-toxic, 100% solids formula with no volatile solvents
Forms a closed-cell foam with excellent durability
Can be used for void filling, rock fissures, or curtain wall grouting
Accelerator allows for controlled reaction times based on temperature

Applications:

Concrete crack injection and joint repair
High-pressure water infiltration control
Curtain wall grouting below grade
Void filling in rock fissures, gravel layers, or soil voids
Underground and foundation waterproofing repairs

Frequently Asked Questions:

What kind of water is needed to activate SikaFix HH+?
The water used for activation should have a pH between 3 and 10. Avoid splashing water directly into the product container.

Can this product be used in high-pressure water leaks?
Yes, SikaFix HH+ is designed for use in high-pressure applications and active water infiltration situations.

Is SikaFix Accelerator required for use?
Yes, use 1 pint of SikaFix Accelerator per 5 gallons of SikaFix HH+ to control gel time and expansion rate.
