03 15 13 Waterstops
Doc | PDFAzo-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 | PDFSealing 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 | PDFThe 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 | PDFPressure 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.
