Aluminate-Based Inorganic Injection Grout
ZRETE Aluminate-Based Inorganic Injection Grout is a high-performance, acid- and alkali-resistant cementitious grout designed for long-lasting protection in harsh environments.
Review technical parametersProduct overview
Performance and application overview.
ZRETE’s Aluminate-Based Inorganic Injection Grout is specially designed for demanding infrastructure projects requiring both high chemical durability and structural performance. Developed with the support of a national-level inorganic materials laboratory, this grout has passed 24-hour exposure tests in 5% sulfuric acid and 48-hour corrosion resistance tests in 10% lactic acid, 10% citric acid, and 10% acetic acid — showing no peeling, no cracking, and outstanding durability。
Its excellent bonding capacity with concrete, steel, and PE liner substrates, combined with its rapid strength development and dimensional stability, makes it a go-to choice for trenchless sewer rehabilitation, wastewater treatment systems, marine environments, and anti-corrosion structural grouting. It also meets long-term durability requirements for both dry and submerged conditions.
