Challenge:
SMRID was challenged with a deteriorating concrete-lined irrigation channel caused by substrate slumping, prompting the need for a cost-effective, adaptable solution that could be tested for long-term viability.
Achievement:
MRID successfully completed a rapid, eight-hour installation of Concrete Canvas using minimal equipment and labor, and deemed the project a success based on its speed and simplicity, with full evaluation pending long-term performance data.
Product Used:
Concrete Canvas®
Location: Vaughan, ON
Project Type: Product Supply
Product Used: Concrete Canvas® CC™ Bulk Rolls
Project Context
In April 2017, 600 sq. m Concrete Canvas (CC) 5mm bulk was installed at the St. Mary River Irrigation District (SMRID) in Grassy Lake, Alberta. The original channel was lined with poured concrete which had been failing due to substrate slumping in certain areas. CC was chosen to be assessed in a test scenario case study by SMRID.
CC had been considered in the past and it was determined that quantifiable results were needed to decide whether CC would be a wide-scale viable solution. Site access, cost of material, labour, adaptability to existing surface conditions were very important considerations. A "Gep-Web" product will also be tested by the SMRID.
The CC was installed over existing damaged concrete surface where cracks had previously been sealed by the SMRID. An anchor trench had been prepared to secure the cloth at the edges along with using 12" spikes. CC was then laid transversely, sealed with SikaFlex 1A and fixed with 1" SS self-tapping screws.
Concrete Canvas® (CC) is a Geosynthetic Cementitious Composite Mat (GCCM), a factory-produced material combining cement within geosynthetic layers that hardens when hydrated for erosion control and weed suppression.
Achievement
The CC was hydrated using a 500 gallon tank and hose with light pressure. The installation took approximately 8 hours to complete using 7 laborers and 1 excavator operator. The SMRID verbally stated that they consider this installation a success. They were pleased with the speed and simplicity of the installation. A testimonial will be given after a couple of seasons worth of use and full judgement is being reserved until performance data on both CC and Geo-Web material has been accumulated.
