Background The Coquitlam Dam is located on the Coquitlam River, 15km (9.3 miles) upstream from its confluence with the Fraser River near the city of Port Coquitlam. The Dam provides additional storage and flows, which are diverted via a tunnel to Buntzen Lake and then to the Buntzen Generating Station. Coquitlam Lake is also used … Read More

Background In conjunction with BC Hydro, Canadian Hydro Developers started the construction of a concrete dam in 2004 to help the Squamish, British Columbia, area generate electricity. This dam was designed to act as an independent power plant, and its bottom 4 m needed enough durability to protect the concrete from the highly erosive forces … Read More

Background The River Erne, at 90 kilometers (60 miles long), is the second largest waterway in Ireland and has been the source of major hydroelectric development since 1946. One of the two massive hydroelectric dam structures on the waterway, Cathleens Fall, needed structural repairs to the 25 meter (82 foot) deep vertical shaft that runs … Read More

Background The Horka Dam built in 1985 had water leakage problems in the maintenance tunnels well below grade. The maintenance tunnels required waterproofing for 1550 cubic meters (55,000 cubic feet) of existing concrete. Solution Krystol T1 & T2 Waterproofing System were used on existing below grade concrete. Since the Krystol application in 1997 no leaks or wet spots … Read More

Background The Revelstoke Dam on the Columbia River was one of the largest of its kind at 175 m (575 ft.) when it was constructed in the mid-80’s. To give you an idea of the enormity of the project, over two million cubic meters of concrete was used to build the dam, constructing a structure … Read More

Background The 500 meter (1600 feet) long outflow tunnel of the Strydom Dam developed severe leakage problems 45 meters (150 feet) below the waterline. Several attempts were made to repair the leaking concrete with repair materials from both Europe and United States. However, all attempts failed to stop the leakage due to tremendous hydrostatic water pressure. Solution In … Read More
