RIGID GROUT > Dual Component Hydrophobic Polyurethane Grout

Rigid Grout A-B

RIGID GROUT

RIGID GROUT is a low-viscosity, dual-component, hydrophobic polyurethane grout designed to stabilize water-bearing soils and fill open voids.

When RIGID GROUT A is combined with RIGID GROUT B, the mixture produces a strong, hard foam that expands to approximately 10 times its original volume. This expansive foam provides structural support and develops an adhesive bond to loose substrates, making it ideal for filling voids adjacent to concrete structures, foundations, and roadways where settlement has occurred. RIGID GROUT is solvent-free, non-toxic, and offers fast foaming and curing for efficient installation.

Key Features

  • Expansive Foam: Expands up to 10 times its original volume, providing strong structural support.

  • Adhesive Bonding: Forms a durable bond with loose substrates such as soil, concrete, and rock.

  • Fast Curing: Quick foaming and curing process allows for efficient installation, minimizing downtime.

  • Hydrophobic Properties: Designed to repel water, making it effective in stabilizing water-bearing soils.

  • Solvent-Free and Non-Toxic: Safe for use in a wide range of environments, without the presence of harmful solvents or volatile materials.

  • Versatile Use: Ideal for filling voids under concrete slabs, roadways, and adjacent to foundations where settlement has occurred.

Applications

RIGID GROUT is ideal for stabilizing water-bearing soils and filling open voids in a variety of situations.

  • It is used for void filling beneath concrete slabs, foundations, and roadways to prevent settlement and provide structural support.
  • The grout can also be applied for slab lifting, effectively restoring alignment by expanding to fill voids under sunken floors, slabs, and roadways.
  • In culverts, tunnels, and underground chambers, RIGID GROUT fills voids adjacent to concrete structures.
  • Additionally, it is used in foundation repair projects to provide stabilization where soil movement has caused structural issues.
  • RIGID GROUT is suitable for infrastructure repair in municipal and heavy civil applications where soil stabilization is critical.
