Grout

A high-density fluid that fills gaps or is used as a reinforcement for existing structures. Inject filler into cracked gaps and cavities in the ground for water leakage prevention work and soil stability in civil engineering work

Inorganic grout for UAM

Projects video
Overview ■ It is injected into the steel pipe inserted into the ground during tunnel excavation, and is used for the steel pipe multi-stage grounding method in which the steel pipe and the ground are integrated and the ground is reinforced by the beam action of the steel pipe.
■ It replaces the existing water glass, develops the required compressive strength in a short time, shortens the construction period and is excellent in economy.
Features ☆ New technology market certified for coating technology "Inorganic quick-connecting grout for steel pipe multi-stage construction method for ground reinforcement during tunnel excavation“
■ The sealing material does not shrink, and the penetration amount after 3 hours of injection is 10 mm or less, and the injection material can penetrate even at 2 mm.
■ Injectables and quick-setting materials have solved the problems that occur when using water glass as an inorganic material.
■ Home-gel strength of 2MPa or more expressed 2 hours after injection of injection material and rapid binding material
■ Ettringite is produced by the hydration reaction between the inorganic injection material and the quick-setting material, and the initial homogel strength and long-term strength are superior to those of water glass.
Usage ■ For ground reinforcement of excavation tunnels

Ground injection material

Overview ■ Composed of Portland cement, slag fine powder and other admixtures, it has a high degree of powder and excellent injectability, a dense structure and excellent chemical resistance.
Features ■ Excellent effect of suppressing temperature rise during hydration
■ Excellent in sulfate and seawater resistance, excellent in suppressing alkali aggregate reaction and excellent in salt blocking property
■ As a cement-based injection material, it does not cause contamination after injection.
■ Easy to adjust the setting time
Usage ■ Soft ground improvement/reinforcement
■ Solidification treatment of roadbed and subground improvement work
■ Abandoned mine filling
■ Landfill, strengthening embankment
■ High water content ground surface layer solidification
