Sealed Path provides specialty grouting services for all areas and industries that require grouting (such as dams, mines, surface and underground structures, oilfield wellbores etc.)  Examples include:

• Water inflow reduction
• Shaft and tunnel pre-excavation
• Soil stabilization
• Civil structure support
• Waste material isolation/encapsulation
• Zonal isolation

Different grouts are more suited than others depending on the geological, pressure/flow, environmental and rock/soil conditions. Combined with economics, supply, equipment, longevity requirements, and safety/ environmental considerations, Sealed Path will design and recommend a grout, or grouts for use tailored to each individual project.

Grouts we have experience with include:

• Cement/Ultrafine, including:
  • Saturated brine based
  • High pressure fluid loss additives
  • Anti-washout
  • Non-shrink
  • Many different cementitious materials, pozzolans, additives and admixtures
• Precipitate grouts
  • Given the right chemistry, solids are precipitated when the grout mixes with the ground water
• Acrylamide, acrylate and polyacrylamide gels
• Polyurethane
• Epoxy
• Emulsion grouts
• Thermal grouts
  • Hot bitumen
  • Wax
• Sodium silicate
• Colloidal silica
• Combination grouts
  • For optimal and specific engineered grout properties
• Multiple other specialty polymers

The selected grout is only one critical component of a successful grout design. We will also provide consulting services and onsite management in relation to:

• Batch plants/equipment
• Hole drilling/prep
• Injection plans, procedures and recommendations
• Grout quality control
• Tracer options
• Acidizing (and safe acid alternatives)
  • To enhance grout penetration and sealing
• Injection monitoring systems
• Results reporting and documentation
• Measurements of success
