Geotextiles
Non-woven & Woven Geotextiles
Armtec carries a full line of Non-woven & Woven Geotextiles for use in a variety of applications. Low initial cost and highly predictable performance make geotextiles very suitable for cost-effective solutions in soil engineering.
Applications:
- Soil separation
- Filtration
- Erosion control
- Sub-grade stabilization
- Protection for membrane liners
- Shoreline protection
- Asphalt and chip seal roadway overlays
High Tenacity Geotextiles
Armtec's High Tenacity Geotextiles are commonly used as integral components in reinforced soil structures such as retaining walls, over steepened 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.
Applications:
- Embankments on weak sub grades
- Sub-grade Reinforcement
- Sub-grade Stabilization
- Over steepened Slope Reinforcement
- Permanent Retaining Walls
- Temporary Retaining Walls
- Voids Bridging
- Veneer
GeoGrids
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 for roadways, parking lots, railways
- Base reinforcements for high embankments
- Base reinforcement for stockpiles, aggregate storage etc.
- Slope reinforcement
Erosion Control Products
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
Sheet Piling
Armtec manufactures lightweight, drivable 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 meters are available. Individual sections are available with pulling holes if required.
Applications:
- Trench shoring
- Culvert headwalls
- Culvert cut-off walls
- Freshwater shore protection
- Freshwater docks
- Loading ramps
Bin Wall Retaining Wall System
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.
Applications:
- Road or rail retaining walls
- Loading ramps
- Bridge abutments
- Freshwater marinas
- Solid waste transfer units
- Aircraft blast walls (military applications)
GeoWeb Cellular Confinement System
Geoweb is a cellular synthetic mat, 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 Geoweb, and within the expanded mat itself will allow these soils to exhibit the characteristics of stronger granular soils. The use of Geoweb can greatly reduce the need for expensive granular materials.
Applications:
- Road base construction in weak soils
- Railroad base construction
- Channel protection for high-flow applications
- Steep slope protection and stabilization
- Retaining wall construction (gravity type)
- Weak subgrade reinforcement
- Road patching and repair
