Durable inorganic solution-type silica sol grout "Hard Riser Seven"
It demonstrates outstanding long-term durability, safety, and convenience. It is suitable for full-scale temporary injection work.
The "Hardlizer Seven" includes the instant-setting type "Hardlizer Seven S" and the slow-setting type "Hardlizer Seven L," making it suitable for all types of injection methods. The "Hardlizer Seven" is a durable inorganic solution type silica sol grout, which was developed in the early 1970s and has made significant advancements as a result of years of research and development, boasting a track record of 50,000 construction cases. The well-known trademark "Silica Sol" in the field of chemical injection refers to the injection material based on non-alkaline water glass obtained by neutralizing the alkalinity of water glass with acid. Notably, research on the durability of chemical injection conducted at the Toyo University Institute of Industrial Technology's Yokokura Laboratory, which began in 1982, clarified the long-term durability of silica sol grout, and this was demonstrated by excavation surveys at construction sites from 17 years ago. Additionally, large-scale outdoor tests have confirmed the permeability and solidification properties after 19 years. 【Feature 1】 1. Excellent applicability: The gel time can range from instant-setting to slow-setting, allowing it to be applied to all types of injection methods. 2. Excellent solidification: It excels in solidification below the groundwater level, ensuring that all injected material solidifies in the soil. It also has excellent water-stopping properties...
