ABOUT ECO GROUTING SPECIALISTS LTD

For almost 25 years, ECO Grouting Specialists Ltd has enjoyed an international reputation as a premier source in soil and rock grouting technology, structural repair techniques, seepage control and prevention and stopping major inflows. ECO has worked on numerous challenging projects, worldwide. Often these have been "emergency response" type projects involving ground treatment for major inflows, structural repair and settlement prevention or ground strengthening.

ECO is familiar with virtually every type of grout of significance, utilized internationally. ECO has extensive in-house experience and expertise both in developing engineered solutions and hands-on training in the practical execution details. In crisis management situations, ECO provides timely and cost effective solutions.

ECO also works with a number of specialists, world leaders in their specialty, to ensure a "complete package" can be provided, using the best resources available. ECO has developed or assisted in the development in a number of grouting processes and technologies:

  • Developed its own wet mill to make fine and ultrafine suspension grouts in a controllable and predictable fashion
  • Revamped the old hot bitumen grouting technology to deal predominantly with massive inflows
  • Developed ISIS: A large laboratory test apparatus to predict injectability (grout spread) in soils and establish the anticipated characteristics of the end product
  • Developed the apparent Lugeon theory (amenability theory), which is the mathematical model for CAGES NS and other real time grouting computer monitoring & assessment systems
  • Developed CAGES NS: A real time computer assisted grouting evaluation system
  • Assisted with the development of the hydro-block, a very fast setting polyurethane/cement grout (auxiliary grouting system).
