Maccaferri opens a new manufacturing facility in California

Modifying soil slope profiles beyond their natural angle of repose, can lead to slope instability. This situation can arise when reducing the footprint of a new highway embankment, or to gain development area on a sloping site.

Maccaferri geogrid reinforcements used in conjunction with the soil, enable the soil to perform better than it would in its unreinforced state. Maccaferri geogrids enable soils to accommodate greater loads and stand at steeper angles. The geogrids are laid horizontally within the compacted soil mass during construction, reinforcing it due to their high tensile strength, low strain and good interaction with the soil.

Maccaferri reinforced soil slopes and MSE walls are ideal with soils that have poor bearing capacity; the structure accommodates differential settlement far better than more rigid solutions. This is also a great benefit in seismic zones.

Our unsurpassed range of geogrid reinforcements, including MacGrid^® WG, Paragrid and Paralink with strengths up to 1,350kN/m (92,504 lb/ft), maximizes the opportunity to reuse on-site materials as backfill to a reinforced slope. This saves on the export and import of materials from the site, embracing sustainability and reducing polluting truck movements. With over 30 years of continuous use around the world, Paralink is one of the most tried-and-tested geogrids in existence.

Cost savings through the reuse of on-site material with geogrids can be substantial on a project. Furthermore, combinations of geogrid types to create ‘hybrid structures’, often create more efficient designs and faster construction compared to traditional techniques.

Maccaferri Terramesh^®, Terrawall^® and Green Terramesh^® combine the flexibility of soil reinforcement with the benefit of a modular system. With factory assembled face elements, and pre-determined dimensions, these systems significantly reduce on-site installation times.

Maccaferri’s reinforced soil slopes and MSE Wall Systems are HITEC evaluated and trusted to support motorways, railway embankments and properties around the globe.
