Reinforced Earth offers ArmaStone® mineral faced steep slopes for the construction of road and rail infrastructure, airports, land development, industrial facilities, waste management and hydraulic works.
ArmaStone® is an engineered solution for reinforced soil slopes (RSS) that require an attractive mineral look, either to mimic the surrounding natural environment or simply to provide pleasing aesthetics for urban and peri-urban infrastructure.
Built as earth retaining structures, slopes are constructed to an angle to horizontal typically between 45° and 76°. These reinforced soil structures are commonly referred to by engineers as Reinforced Soil Slopes (RSS) or Geosynthetic Reinforced Slopes (GRS). Reinforced Earth’s success in this field has led to solutions that have reached a world record-setting RSS structure being built to a height exceeding 100m.
What are Reinforced Mineral Faced Steep Slopes?
Reinforced soil slopes are essentially an extension of the Reinforced Earth® technique, and are designed and built to retain engineered reinforced soil fill with a face inclination of between 45° and 76°. Generally Reinforced Earth will offer provisions for the finished facade to be either vegetated with ArmaGreen®, or a mineral facade with ArmaStone®. Face-forming elements primarily consist of an engineered welded wire mesh system to which alternating layers of geostrips, geogrids, or steel strips are attached to function within the engineered fill for tensile strength and pullout resistance.
RSS structures are widely built as functional structures to support transportation infrastructure, industrial sites, landscape development, protective structures, landfills and hydraulic structures.
Applications
Steep slopes are used for the very diverse applications such as:
- earth retaining structures
- platform support
- slope rehabilitation
- gravitational risk protection (rockfall, landslides, avalanches)
- protective bunds (sight barriers, explosion and assault barriers, sight and noise barriers)
- flood levees and dikes
- landfills
Design flexibility
Our unique approach provides engineers and builders with a range of technical solutions to best address your particular project requirements. This allows for designers to combine choices of facing elements with an unique selection of soil reinforcements. Facing elements and soil reinforcement components are precisely engineered by Reinforced Earth on a project-specific basis, whether being permanent or temporary slope structures.
Mineral facing
As outlined above, ArmaStone® is an engineered solution for reinforced soil slopes which require an attractive mineral look, either to mimic the surrounding natural environment or simply to provide pleasing aesthetics for urban and peri-urban infrastructure.
