Simpson Strong-tie 9 Oz Crack-pac Flex-h2o Polyurethane Concrete Sealant Kit

Discover the performance of the Simpson Strong-Tie Crack-Pac Flex-H2O kit, a trusted solution for concrete crack repair and water control. Built for effortless application, this polyurethane injection system uses a resin cartridge paired with an accelerator housed in the nozzle for clean, controlled mixing. It targets cracks from 1/32 to 1/4 inch wide in concrete or solid masonry. When the resin meets moisture during injection, it expands into a pliable seal that blocks leaks and resists recurring water intrusion.

How It Helps You: This compact kit delivers reliable protection for foundations, basements, and concrete walls by stopping leaks at the source. The flexible polyurethane formulation accommodates minor substrate movement, maintaining a durable seal through temperature changes and settling.

• Seals cracks ranging from 1/32 to 1/4 inch wide, ideal for effective concrete crack repair and masonry crack sealing
• Water triggered expansion creates a flexible, watertight seal that stops active and dormant leaks
• Cartrigde resin with accelerator in the nozzle enables precise, easy dispensing for crack injection
• Suitable for concrete and solid masonry surfaces including foundations, walls, and slabs
• Supports structural restoration and moisture management with a durable, movement-tolerant seal

Why This Product Stands Out: Choose this Crack-Pac Flex-H2O kit for quick, dependable crack sealing and moisture control in both new construction and restoration projects. The straightforward application process, proven polyurethane chemistry, and flexible seal deliver lasting performance against water intrusion, while enabling professional-grade results with minimal downtime. This kit helps protect foundations, basements, and walls from moisture-related damage and reduces long-term maintenance costs.
