Seal Boss 1640 Structural Foam 10 Gallon Unit

Seal Boss 1640 Structural Foam is a closed-cell, two-component, non-shrink polyurethane foam with structural properties. This MDI (methylene-diphenylisocyanate) based product is 100% solvent-free and 100% solids. The product starts to react when mixed and does not need moisture from external sources for the reaction. SealBoss 1640 expands up to eight times forming a closed-cell structure and cutting down the material consumption drastically. The cured foam offers limited structural strength combined with an increase in volume and excellent bonding properties on dry and with limitations on wet surfaces. The product is not a replacement for typical epoxy injection but offers an alternative for filling larger spaces that demand limited structural strength. The compressive strength of the reacted product is typically much higher when filled with an inert mineral such as sand.

SealBoss 1640 is designed to fill voids in soil and stone, brick, or concrete structures for the purpose of waterproofing as well as regaining certain structural strength. The excellent combination of hardness and flexibility qualifies SealBoss 1640 for use in areas where structural strength and moderate flexibility is desired.

SealBoss 1640 is an excellent soil solidification foam which can be used to seal, lift, fill and densify soil. It also used next to or under structures such as roadways, driveways, runways, patios, and other buildings by utilizing a deep grout injection process.

The expanding and compressive strength qualities of SealBoss 1640 makes it a price competitive alternative for the filling of large voids and 'pockets'. The structural strength of the foam product is highly correlated to the expansion rate and the use of inert fillers such as sand. SealBoss 1640 can be applied in dry and wet areas. Additional moisture may increase the expansion. The standard mixture expands approximately six times in volume. Job site testing is recommended to determine product suitability. To achieve the most satisfying and permanent results in certain applications, a combination of SealBoss 1640 with other systems of our product line may be advised. SealBoss 1640 is not designed to stop high-velocity water leaks. To stop active water leaks please refer to SealBoss 1510 Water-Stop-Foam. Ask your SealBoss technician for details.
