■ Usage

  • ● Ground strengthening: soft ground stabilization, ground subsidence prevention, and strengthening of nearby ground during excavation and drilling
  • ● Inflow and leakage stopping: preventing inflow in tunnels, subways, reservoirs, etc., as well as during excavation of water conduits, sewer pipes, community ditches, etc.

NITROC™ Series

As a chemical solution that mainly consists of Sodium Silicate No. 5 and NITROC™ Main Agent, it has the following features compared to No. 3 water glass: (1) excellent penetration, (2) high concentration at a high mole ratio, and (3) less water release. It is also more effective when used in combined injection and double packer methods.

Feature

  • Instantaneous and medium gel time obtainable with a small amount of curing agent

  • Stable cured body formed and excellent watertightness demonstrated

  • Low main agent viscosity and good penetrability of the ground

  • Little influence by groundwater dilution and excellent solidification

Tai-Q™ Series

Tai-Q C4000 is an ultra-fine particle-type durable grout material developed via many years of research on soil stabilizers. Applicable with the double pipe strainer and the double packer method.

Feature

  • Blast furnace slag, which produces hydrated compounds similar to ordinary cement, is used as the main agent with long-term durability*

  • Excellent permeability can be expected due to the use of ultra-fine particles in the main agent

  • Strength can be adjusted to the purpose (standard strength, high strength, ultra-high strength)

  • Excellent work efficiencyOnly two or three products are needed for excellent results

*According to our research
