Azo-Grout™ Applications, Specifications, Brochures

Applications

Injection grouting and soil stabilization

Demonstration of drilling of injection holes, installing packers
and using commercial pump for injecting Azo-Grout™ in a leaking caisson wall.
Material reacts to stabilize soil and stop the water flow.

Sealing crack in precast joint

Waterstop reaction in high water flow manhole situation
Observe the high pressure leak and the injection of the
Azo-Grout material as it completely stops the water flow under extreme conditions.

Specifications

Division, title	Application and uses:
03 64 00 Injection Grouting Doc \| PDF	Azo-Grout™ 424 hydrophobic polyurethane injection material forms a flexible foam to stop water infiltration in concrete structures, including concrete cracks, underground parking garages, municipal and utility facilities, and concrete dams and powerhouse galleys. The potable water-approved system is also available in cartridge form.
03 15 13 Waterstops Doc \| PDF	Azo-Grout™ 424 hydrophobic polyurethane material forms a flexible foam to stop water infiltration in concrete structures, including concrete cracks, underground parking garages, municipal and utility facilities, and concrete dams and powerhouse galleys. The potable water-approved system is also available in cartridge form.
03 01 00 Maintenance of Concrete 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.
31 32 23 Pressure Grouting Soil Stabilization Doc \| PDF	The soil stabilizing properties of Azo-Grout™ 443-C 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.
31 43 13.16 Concrete Raising 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.
