Titan Environmental is a Canada-wide company with a suite of geosynthetic and civil construction products – including trademarked products– that offer innovative solutions to some of the most common problems in the mining industry.
Take, for instance, building an access road on swampy terrain or saturated sub-soils. The typical solution calls for aggregate, aggregate and more aggregate. Even then, long-term stability is hard to achieve and accidents in heavy haul trucks are inevitable.
But with Titan’s Swamp Grid geogrid, the volume of aggregate can be reduced by as much up to 40% and the roadbed is far more stable than a conventional base. Titan president Kelly Sitarz describes the product as a geotextile with high filtration properties and a high-strength biaxial geogrid surface.
“It’s a very cost-effective product,” Sitarz says. “You roll it out over the swamp like a carpet then pour aggregate over the Swamp Grid, which works like a snowshoe. It disperses the weight of the load. With a more stable structure, you have fewer accidents.” A great example of this is a Mine Haul Road stabilization project in Northern Ontario using Titan’s Swamp Grid™. This project involved the construction of haul roads built on compacted clay with blast rock/granite. These haul roads extend into a mine pit providing passage for rock dump trucks weighing several hundred tons. The conventional solution for this challenge would consist of using 1.0m of compacted crushed rock backfill (aggregate base) over the compacted clay subgrade. However, the Swamp Grid™ solution provided the mine with significant cost savings by allowing them to use 0.7m thick aggregate base rather than 1.0 m thick. This reduced overall construction costs while also decreasing the environmental impact from aggregate harvesting and hauling.
Mine-Shield Grid is Titan’s other trademarked product and was developed for use underground in hard or soft rock mines. It is an alternative to the steel mesh, shotcrete and rock bolts typically used to stabilize tunnel roofs, ribs and walls. The product comes in two types of material – polyester and polypropylene with fire retardant and anti-static properties, the one ideal for roofs, the other for ribs and walls. Either product can be produced to specific roll lengths, widths and grid aperture opening without compromising the structural integrity.
“It’s a great advancement,” says Sam Bhat, Titan’s CTO of Geosynthetics. “Mine-Shield Grid is lightweight, high strength, and easy to install. It can reduce the installation time for longwall screenings from weeks to days and is also much safer to handle than steel mesh reducing the risk of injury.”
The specifications of both Swamp Grid and Mine-Shield Grid have been tested and verified by technical experts at several leading Canadian universities and accredited independent third-party laboratories. In addition, says Bhat, Mine-Shield Grid has been put to the test and been proven effective at underground mines in Australia since 2015.
Titan has rounded out its suite of products for mining applications by acquiring exclusive Canadian distribution rights to Concrete Canvas, which was developed in Britain, and Bituminous Geomembrane (BGM liner).
Ron Drewry, Titan’s Concrete Canvas Specialist, describes it as concrete on a flexible roll that hardens when properly hydrated. The product is used around the world in 54 countries in numerous applications, including the mining sector. In Canada, Concrete Canvas is used in mining projects in British Columbia, the Yukon, and Ontario for spillway and channel lining, among other things, or underground for mine vent wall construction to reduce ventilation costs, which are major costs in any underground mining operation.
