Engineered Containment was provided the opportunity to work on another multi-layered geosynthetic storage pond project in NE BC that was due to be constructed through the summer/fall of 2015.

The project design scope included the supply and installation of a geosynthetic ground water management system, leak detection systems, and three layers of containment geomembrane liners. ECI worked with all the project stakeholders during the bidding stage and offered a valued added alternate to the specified geomembrane liner design. The valued added alternate LLDPE geomembrane was reflective and white in color and incorporated a specialty electrically conductive geomembrane liner formulation. Some key performance properties of a white reflective geomembrane are:

• Reduction of geomembrane wrinkling due to lower thermal expansion which helps improve the installation quality

• Reduction in liner surface temperature to lower thermal expansion and contraction of liner.

• Enhancing durability with reflected UV irradiation

• Efficient visual identification of surface defects due the contrast of the white surface and the black layers of geosynthetics below.

The electrically conductive nature of the liner allowed ECI to perform rigorous post installation non-destructive QAQC testing over the entire surface area of the conductive geomembrane layer. The non-destructive spark testing allowed ECI to efficiently identify any damage on the white conductive geomembrane layer that could result in a breach of the liner surface. The non-destructive testing completed on site identified a few suspect areas which were easily repaired. The repairs were completed and tested in accordance with ECI's extensive QAQC repair and testing procedures.

ECI’s value added liner design options were well received by all project stakeholders. The project was complete on time with all project stakeholders pleased with the finished product.
