High Tenacity Geotextiles Armtec's High Tenacity Geotextiles are commonly used as integral components in reinforced soil structures such as retaining walls, oversteepened slopes and embankments constructed on weak soils. These geosynthetics provide tensile strength to the soil, thus enhancing its shear strength characteristics. This enables walls, slopes and embankments to be constructed cost-effectively and quickly. Mirafi® geosynthetics, from Armtec, that are used for soil reinforcement, have been designed to offer the optimum in performance characteristics.
Geogrids are open-mesh polymer-based geosynthtics designed to enhance the performance of granular soils. By combining the tensile strength of the synthetic grid with the friction and interlock properties between the soil and the grid a composite soil-grid structure can be constructed. The chemical resistance of the grid ensures long-lasting structures with high performance.
Two types of grid are available:
Uni-Axial geogrids are used in the following applications:
Soil reinforcement
Block or segmental retaining walls
Steep slope reinforcement
Void bridging in weak soils
Bi-Axial geogrids are used in the following applications:
Base reinforcement & soil stabilization for roadways, parking lots, railways
Base reinforcements for high embankments
Base reinforcement for stockpiles, aggregate storage etc.
The optimum erosion control measure is well-established vegetation. In order to promote rapid establishment of newly planted or seeded vegetation, erosion control blankets and turf reinforcement mats are used. Armtec carries a comprehensive line of these products.
Products available include:
Straw blankets
Coconut fibre blankets
Synthetic fibre mats
Heavy duty synthetic turf reinforcement mats
The products are pre-engineered for use in:
Channels
Slopes
Areas requiring surface erosion control
Landscaping projects
Fascias on geosynthetic-reinforced steep slopes
The features and benefits of erosion control products include:
Reduced soil loss due to runoff
Rapid seed germination and growth
Reduced surface water velocity
Conservation of soil moisture
Protection from wind and rain sheer
Weed suppression
Enhanced root development
All products are biodegradable for optimum environmental management
Armtec manufactures lightweight, driveable sheet piling for use in many applications. Sheet piling is available in galvanized or black steel and is of the interlocking edge type. Standard widths of 500mm and lengths of up to ten metres are available. Individual sections are available with pulling holes if required.
Armtec Bin Wall is a sectional gravity-type retaining wall system manufactured from rugged and durable galvanized steel components. The system consists of a series of interconnected open-bottom steel boxes, infilled with granular material, with a height and depth designed to resist overturning and sliding forces typical of a gravity wall system. All connections are bolted at site.
Standard factory components can be used to construct walls with heights up to ten metres and depths approaching four metres. Standard section width is 3 metres. Walls can be installed on side slopes, lateral slopes, on curves and with changes in elevation either below the wall or above it.
Features and benefits:
Sectional layout ensures maximum flexibility in configuring any kind of wall
Light individual sections allow installation with light equipment
Fully nested parts allow for economical shipment over long distances
Infill material is granular, generally available close to site.
Flexible, bolted design can accommodate reasonable differential settlement
Cellular confinement systems are designed to be used in conjunction with
granular or weaker soils in order to create an engineered-grade composite
fill material. Confinement of a weaker soil within the individual cells of
the mat, and within the expanded mat itself will allow these soils to
exhibit the characteristics of stronger granular soils. The use of a
cellular confinement system can greatly reduce the need for expensive
granular materials.
Reinforced steepened slopes, also termed Mechanically Stabilized Earth (MSE) slopes, are defined as structures with face inclinations of less than 70 degrees. Steepened slopes have become increasingly popular due to the desire to increase land usage and decrease site development costs.
