Aqua Dam® Flood Protection System - Manitoba Aqua Dams® were used to protect hundreds of homes, communities, and arterial roadways throughout southern Manitoba during the flooding season. Layfield developed a Rapid Deployment trailer which consisted of Aqua Dams®, pumps, suction & discharge hoses. Aqua Dam® can be installed 10 times faster than a conventional sand bag berm for approximately half the cost. » More ...
Geotube® Sludge Dewatering Tubes Geotube® units or containers are constructed of a specially engineered textile designed for sludge dewatering applications. Geotube® containers are filled using sludge slurry with a high concentration of water in order to allow for easy pumping. The excess water then filters through the walls of the soil tube leaving the solids trapped inside the unit. » More ...
Choosing the Right Geomembrane for Water Containment Water containment is one the largest applications in North America for geomembranes. It encompasses many sectors including government, agricultural and the resource sector. Common applications include containment of potable water, wastewater treatment as well as freshwater and reclaimed water storage and protection. When selecting a suitable geomembrane for water containment a number of important geomembrane performance characteristics should be considered. » More ...
Floating Cover and Liner for Water Reservoir - City of Astoria, Oregon The City of Astoria had two uncovered potable water reservoirs that they had to cover in order to maintain EPA and AWWA standards. They have experienced multiple problems with birds bathing, frogs hatching, and dirt and debris landing in the reservoirs. Layfield completed the installation of the liner, floating cover and baffle curtains, taking approximately 55 days to complete the installation. » More ...
Baffle Curtain - City of London, Ontario The City of London commissioned the construction of a new pumping station and reservoir including a 115,000 cubic meter underground concrete tank to hold a 7 day supply of drinking water for the City. Layfield installed an integrated flexible baffle curtain system that included 11 curtains, each 8.4 meters high x 55 meters long in two separate clearwell cells. » More ...
StormChamber - Conestoga College - Cambridge, Ontario The plan for this site was to allow for stormwater to be captured and directed to underground infiltration galleries within the parking lot and underneath a sports field. Due to the high groundwater table, a shallow system was required to provide a high volume of storage with a low profile that would infiltrate and recharge the groundwater. The StormChambers^TM System was selected due to significant cost savings in reduced material costs, a smaller excavation, and reduced aggregate fill. » More ...
Atlantis Storm Water Detention - Abbotsford, British Columbia An Atlantis Storm Water Detention System reduced the site surface water speed and volume in a Shell Gas station in Abbotsford, BC by detaining the rain surge water in, and then releasing it slowly over a long period of time. The main benefit of the Atlantis Storm Water Detention System is that it achieves better storage capacity within a smaller footprint while allowing for the space above the tank to be used for parking and landscaping. » More ...
Turbidity Curtain - Davy Crockett Shipwreck - Washougal, Washington The Davy Crocket is a 229 feet barge that was shipwrecked in 1965, but was exposed three decades later by shifting sands in the Columbia River. One of the main challenges was to contain the oil, chemical, and sediment discharge with a sheet pile cofferdam installed around the vessel during deconstruction and salvage operations. A Layfield Type 1.DOT silt curtain was used to contain the contaminated sediment disturbed by the deconstruction operations. » More ...
Firecode Compliant Geomembranes - Hazgard® 535 Hazgard® 535 meets the National Fire Code in Canada and is one of the many specialty geomembranes available for secondary containment. This fire retardant, chemically resistant material is ideal for most fuel containments, including biodiesel and can be installed in extremes temperatures. HAZGARD® 535 can be prefabricated to size and delivered to site in one piece eliminating the need for field seams in small containments. » More ...
