Where the soil or ground is not inherently stable it will be prone to failure; the performance of the existing soils needs to be improved. There are many ways to achieve but increasingly geogrids are used to reinforce the soils within embankments or slopes.
- Soils are good in compression and poor in tension
- Geogrid reinforcement is good in tension and poor in compression.
A composite of these materials offers the benefits of both; Geogrid reinforcement, used in conjunction with the soil enable that soil to perform better than it would in its unreinforced state, accommodating greater loads or standing at steeper angles for example.
With our specialist knowledge and comprehensive product range, Maccaferri can offer cost-effective solutions to your slope reinforcement problem, whether on a steep, shallow or soil nailed slope.
Our unsurpassed range of geogrid reinforcements maximises the opportunity to reuse site won materials as backfill to a reinforced slope. This saves on the export and import of materials from site, embracing sustainability and reducing polluting truck movements. Cost savings through the reuse of site won material with geogrids can be substantial on a project.
Vegetation of the finished reinforced slope is important. Our soil bioengineering expertise can assist in the selection of appropriate seed mixes, topsoil and erosion protection products.
Our reinforced slopes are trusted to support motorways, railway embankments and property around the UK and Ireland. Try us on your next project.
Shallow Slopes ≤45° (Click Here) Shallow slopes may require a geogrids wrapped faced structure, where the angle of the slope exceeds the natural internal angle of friction of the soil. If the slope is structurally stable without geogrids, surface reinforcement may be required.
Steep Slopes 45-70° (Click Here) These solutions are usually geogrid ‘wrapped face’ structures. Geogrids are compacted within the backfill material, reinforcing it. The geogrids are wrapped up the face of the structure, encapsulating the material behind, before returning into the slope above. Combinations of types and strengths of geogrids can be considered to optimise designs.
Soil Nailed Slopes (Click Here) Where there is not enough space on a project to construct a reinforced soil slope, it may be possible to use Soil Nailing. With soil nailing providing the overall slope stability, Maccaferri can offer flexible surface reinforcement and protection options for use between soil nails.
