CHALLENGE
The primary challenge was to construct a reliable anti-filtration barrier around a tailings dam to prevent toxic waste materials from contaminating the surrounding environment.
GROUND CONDITIONS
The soil at the site consisted of compacted sandy layers and deeper fat clay with low plasticity layers, presenting a great challenge for installation. The maximum value of nSPT blows was 48! The use of Ecoseal sheet piles with integrated gaskets provided a secure seal even in these varied soil conditions.
SOLUTION
Ecoseal vinyl sheet piles were chosen for their superior watertightness and durability. The sheet piles were installed around the 5.5 mile perimeter of the tailings dam, driven to a depth of 36 feet, 4 feet into fat clay layer. This installation ensured a continuous and impermeable barrier, effectively containing the tailings and preventing seepage. In total, 753 400 ft2 of Ecoseal sheet piles were used.
