  • Optimizing Injection Strategies and In situ Remediation Performance
    Pressure-activated injection tools are ported injection tools with a spring-loaded pressure-activated opening device that moves a metal slider to expose the injection ports They are advantageous in flowing sand conditions and in tight formations
  • General Information About Injection Wells | US EPA
    This webpage provides general background information on injection wells used to place fluids in the subsurface It also provides information on use, different categories, and how they are regulated
  • Injection Wells: A Guide to Their Use, Operation, and Regulation - GWPC
    As shown in Figure 13, Class II injection well construction is designed to properly confine injected fluids to the authorized injection zone and prevent the migration of fluids into USDWs
  • Injection Wells: Direct Groundwater Recharge Technique
    One of the most targeted approaches is the use of injection wells – structures designed to push treated surface water directly into aquifers under pressure, bypassing the slow and often impractical process of natural surface infiltration
  • Sika® Injection Systems
    A hydrophobic polyurethane foam grout that, when used with the accelerator, is designed to stop water infiltration and fill voids outside structure or joint and cracks in concrete structures
  • Injection Grouting to Stop Groundwater Inflow and Infiltration
    Injection grouting to stop groundwater inflow and infiltration is a cost-effective solution many municipalities turn to when faced with this issue But what is groundwater inflow and infiltration and how does injection grouting solve the problem? Let's start with some definitions
  • Groundwater Control: Exclusion Techniques - Structville
    Injection grouting is a process by which grouts are injected under pressure into open fissures, voids, cracks, and pores in a soil rock mass The grout fills the pore spaces, preventing the flow of water through the soil
  • Different Types of Grouting in Soil - Structural Guide
    Grouting involves injecting a fluid-like material into the ground to fill voids, improve strength, control water flow, and enhance the overall stability of soil
  • soil injection — Eco-Soil Stabilizers
    The Eco-Soil Stabilizer treatment lowers the pH of the clay soil to its iso-electric, or natural state At this lower, natural pH point, the clay stops acting as a water magnet, and releases the excess water, which separates from the soil through drainage, evaporation or soil compaction
  • crack injection, waterstop injection, chemical grouts, polyurethane . . .
    Water activated, hydro-active, polyurethane two component water-stop injection foam in Cartridges expands up to 30-40 times Used to stop water, to fill voids, hairline cracks and for soil stabilization Also available in bulk packaging
