Challenge
The Silverberry Landfill project featured a hazardous
waste secure landfill that required a reliable closure cap to
reduce leachate infiltration and limit environmental risk.
The solution needed to meet strict regulatory standards,
perform in subzero temperatures, and be installed quickly —
within a tight 37-day window during the middle of winter in
northern British Columbia.
Solution
Siplast delivered a durable bituminous geomembrane engineered for environmental containment and extreme climate conditions:
- Engineered for cold-weather performance
Teranap 431 was selected for its flexibility and workability in freezing February temperatures, making it ideal for use in challenging winter conditions. - UV stability for long-term exposure
The membrane offered excellent resistance to UV degradation, providing the durability needed for long-term performance in an exposed landfill cap. - Fast installation for regulatory compliance
Despite freezing conditions, the system was successfully installed within the project's 37-day deadline, helping the site meet its environmental and operational timelines without compromise.
By using Teranap, the project team completed a high-stakes landfill closure that supports environmental protection and long-term containment — even under the toughest conditions.

Teranap Geomembrane
Reliability. Efficiency. Practicality. Three characteristics that are desirable in any construction product. But when you are talking about geomembrane applications, these three characteristics take on a whole new significance. The sheer scale of some geomembrane applications underscores this point. Lining canals, reservoirs, and ponds full of millions of gallons of water is serious business. And even on applications that are smaller in scale, the impact of a waterproofing problem can be enormous.
