Outfall Lining - Harrison Lake, BC

The project site at Harrison Lake, B.C. was remote with no road access, requiring all materials to be transported by barge. Additionally, installation was dependent on lake water levels dropping to a specific point, creating a narrow and unpredictable window for execution.

The Titan Solution

Kingston Construction prepared the site by clearing debris, compacting the substrate, and installing lock blocks around the outfall perimeter. Using an excavator, they dispensed 13mm Concrete Canvas® bulk rolls, which were anchored in trenches and sealed with Soudaseal and screws at precise intervals to ensure durability and water resistance.

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

In July 2020, 500 sq. m of Concrete Canvas® was successfully installed to line the outfall, demonstrating effective planning, adaptability, and execution under challenging logistical and environmental conditions.
