Cementitious

Cement based grouts are most commonly used by GEC. In most of our grouting applications, these grouts offer the most appropriate properties for the job and in general are the least expensive grout material. Cementitious grouts can be applicable for any type of grouting service, as long as the aperture being grouting is large enough to accept the cement particles.

GEC has a track record of completing jobs successfully with neat cement grouts with the use of dispersants. Although these grouts are appropriate for many jobs, we also have the ability to design cementitious grouts with enhanced properties when the conditions necessitate. Common grout properties that may be adjusted include:

  • Viscosity
  • Bleed
  • Pressure Filtration
  • Thixotropic Set
  • Initial and Final Set
  • Cohesion
  • Compressive Strength
  • Permeability
  • Density

These properties may need to be controlled to improve grout for reasons such as pumpability, penetration, anti-washout characteristics, grout mobility, etc. Through the use of additives, all of these grout properties can be adjusted. GEC has designed cementitious grouts for pumping in lines as small as quarter inch diameter, for distances as long as two miles, for underwater placement in open fractures, and for gaining control of water discharges up to 1,800 gpm. Additionally, GEC has designed and utilized Balanced Stabilized Grouts (BSG) which are completely compliant with some of the most rigorous specifications in the industry.
