Doc | PDF
Sealing concrete structures to prevent water permeation: The flexible to rubber-like foam properties of Azo-Grout™ 675 make the hydrophilic polyurethane injection material ideal to stop water infiltration in below-grade concrete structures, especially municipal and utility facilities, pedestrian and automotive tunnels, and concrete dams and powerhouse galleys.

Doc | PDF
The soil stabilizing properties of Azo-Grout™ 443 prevent erosion in a variety of soil types by forming a rock-like mass that provides structure and stabilization. Shoring excavations, deep-dug holes, river and lake embankments, and sand traps on golf courses benefit from the injection of this safe and easy-to-use hydrophobic grout.

Doc | PDF
Pressure grouting polyurethane: The ability to expand up to 10 times its liquid state while maintaining a closed-cell structure makes two-component Azo-Grout™ 551 with Azo-Nate™ 300 an excellent applicant for underground void filling and slab lifting of floors, roadways and sidewalks. The rigid closed-cell foam is also an effective stabilizer in water-bearing soils.
