The Pozidrain product range is also installed as part of remediation plans for contaminated ground so that the former tailings storage facilities are permanently capped to prevent rainwater infiltration and block pollutants from entering nearby water sources.
ABG manufacture Pozidrain® K geocomposite drainage and capping barrier as the most advanced system for mining and capping applications. The all-in-one geocomposite system comprises an impermeable back HDPE cuspated drainage core with extended flat selvedge for overlapping and geotextile bonded on one or both sides.
Pozidrain K all-in-one geocomposite capping and drainage system is available in 4, 6 and 7mm thickness with single or double geotextile filter.
The unique all-in-one Pozidrain geocomposite drainage and geomembrane lining is typically installed to the upstream face of the tailings dam and performs an integral function within the dewatering design, with high drainage flow capacity in both directions with impermeable HDPE underside and flat selvedge for overlapping.
Leak detection layers
Drainage composites are also specified as leak detection layers between multiple linings of tailings containment systems. The high compressive strength core allows flow of particle laden liquids without the risk of clogging, even under very high loads.
Haul road routes
Any temporary or permanent unpaved surface subject to heavy vehicle trafficking needs a correctly engineered, but economic design, especially where weak subgrade conditions are present. This ensures optimum use of resources and provides a reasonably smooth surface, with tyre loads distributed evenly to prevent rutting and meet the required design life.
Our design department has many years’ experience in designing unpaved roads over weak CBR subgrades. We are able to offer cost-benefit advice on which solution is best suited to your project, utilising one – or a combination of – geogrids, geocells and geotextiles that deliver a lower carbon footprint.
ABG can offer a geogrid-stabilised, reduced road foundation thickness for weak subgrade conditions, utilising the benefits of geosynthetics to improve the layer stiffness / drainage quality within the AASHTO pavement design approach. This increases the lifespan and / or reduces the thickness of the overall pavement. We can apply one, or a combination of geogrids, geocomposites and geotextiles to benefit our clients in the design of flexible road foundations. Please contact ABG to discuss your project specific design requirements.
Slope stabilisation
ABG offer a slope reinforcement design service utilising our wide range of geogrids, geotextiles and drainage geocomposites to provide stability to suit the specific site ground conditions and to achieve the slope dimensions required for the project.
ABG applies bespoke drainage geocomposites, with or without a geogrid, for veneer stability applications on slopes for mining applications to restore a sustainable and aesthetic green surface. The drainage geocomposites used in the veneer stability assessments are easy to install and virtually impermeable – eliminating the need for an expensive combination of geomembranes, GCL and granular drainage layers and providing a reduced carbon footprint in the process.
