Regional Information
Product specifications and applications by region
Regional Overview
In BC, GEOMODS NW140 is extensively used in mining operations, transportation projects and environmental works. Its high tensile strength and puncture resistance make it ideal for use in rugged terrains, like the mountainous regions of BC. The product's water flow rate and apparent opening size make it effective for drainage in rainy coastal conditions.
Notable Projects
Project 1
Highway 1 expansion project
Project 2
Red Chris Mine operations
Climate Considerations
The GEOMODS NW140 performs effectively across a wide range of temperatures, from -40°C to +30°C, making it suitable for BC's varied climates. It's particularly effective in rainy coastal conditions due to its superior lateral drainage capabilities.
Industry Applications
Mining
Used in BC mining operations for subdrains and foundation drains, GEOMODS NW140 provides essential ground stabilization and water management.
Transportation
In transportation projects, such as the Highway 1 expansion, it's used for its excellent drainage properties and soil reinforcement capabilities.
Environmental
It's also used in environmental projects for its effective drainage across a range of soil permeabilities, helping to manage water flow and prevent soil erosion.
Regional Overview
In Alberta, GEOMODS NW140 is widely used in the oil & gas industry, mining, and major transportation projects. Its high tensile strength and puncture resistance are ideal for the harsh conditions found in oil sands extraction sites. The product's water flow rate also makes it effective for drainage in Alberta's varying climates.
Notable Projects
Project 1
Athabasca Oil Sands project
Project 2
Edmonton Ring Road construction
Climate Considerations
The GEOMODS NW140 performs effectively in Alberta's extreme cold winter temperatures, as low as -40°C, and in the hot summer months, up to +30°C. Its superior lateral drainage capabilities make it suitable for use during Alberta's spring breakup season.
Industry Applications
Oil And Gas
In the oil & gas industry, it's used for its durability and strength in subdrain applications in oil sands operations, providing essential ground stabilization and water management.
Mining
In mining operations, its puncture resistance and tensile strength provide essential support and water management.
Transportation
Used in major transportation projects like the Edmonton Ring Road, for its excellent drainage properties and soil reinforcement capabilities.
