About ECO
ECO was founded 30 years ago by Alex Naudts in 1982. ECO Grouting Specialists has earned an international reputation as a premier source in grouting technology. We specialize in providing practical solutions for soil and rock grouting challenges, structural repair techniques and remediation of geotechnical problems. ECO has worked on numerous challenging projects worldwide. Often these have been “emergency response” type projects involving ground treatment for major inflows, structural repair, settlement prevention and 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 as it pertains to 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 of numerous grouting processes and technologies:
Developed its own wet mill to make fine and ultrafine suspension grouts in a controllable and predictable fashion.
Revamped traditional hot bitumen grouting technology to deal predominantly with massive inflows.
- Hot Bitumen Grouting: The antidote for catastrophic inflows
- Hot Bitumen Grouting – Rediscovered (Heiβbitumenverpressung – wiederentdeckt)
- Pre-excavation Grouting Through water bearing zone under high pressure under extreme flow conditions
- Stewartville Dam: Hot Bitumen Grouting Introduced in Canada to stop Major Seepage, Ontario
- New Yung Chung Tunnel: Hot Bitumen Grouting, Taiwan
- Milwaukee Tunnel Grouting, Milwaukee, Wisconsin
- Hot Bitumen Grouting Stops Major Inflow, Philippines
- Hot Bitumen Grouting to Reduce Inflow in a Limestone Quarry, Milleville, West Virginia, USA
Developed ISIS: A large laboratory test apparatus to predict injectability (grout spread) in soils and establish the anticipated characteristics of the end product.
- Lab Testing
- Advanced Grouting Program at Penn Forest Dam Results in Reduced Construction Costs and High Quality Product.
Developed the apparent Lugeon theory (amenability theory), which is the mathematical model for CAGES and other real time grouting computer monitoring & assessment systems.
- Advanced Grouting Program at Penn Forest Dam Results in Reduced Construction Costs and High Quality Product.
- C.A.G.E.S.
Developed CAGES: A real time computer assisted grouting evaluation system.
- Advanced Grouting Program at Penn Forest Dam Results in Reduced Construction Costs and High Quality Product.
- C.A.G.E.S.
Assisted with the development of the hydro-block, a very fast setting polyurethane/cement grout (auxiliary grouting system).
- Solution Grouts
- Irreversible changes in the grouting industry caused by polyurethane Grouting: An overview of 30 years of polyurethane grouting
Developed the use of OCSP’s (Overburden Casing Outfitted as Sleeve Pipe) to facilitate the grouting of the contact zone between rock and overburden, typically the Achilles heel of grout curtains.
