ECO designed and directed a variety of grouting rehabilitation projects of historical structures along the Rideau canal…
ECO’s amenability theory was extensively used to supress costs…
A pre-excavation program was designed to tunnel beneath an active CP Rail track…
ECO has designed and directed the construction of several mine plugs and permanent flood bulkheads. The plugs have been used to seal underground works after the ore has been depleted or to seal off areas of a mine where the water inflow impaired or threatened mining operations…
For the construction of an underground shaft, a low strength inflammable backfill grout had to be designed to prevent direct load transfer from a squeezing rock formation, preventing it from exerting excessive pressure on the shaft liner.
Grouting techniques can also be used to prevent wind erosion and keep moisture in the soil. A four acre miniature forest was grown in the Sahara desert (Southern Tunisia) using a specially developed solution grout. It was sprayed on the sand after small Acacia Cyanaphylla trees were planted.
