Geosynthetics have been used successfully in stabilizing steep slopes of residual soil and weathered rock. Geotextiles placed horizontally in layers have helped to prevent landslides, which are generally induced by heavy rainfall. The tensile reinforcement and filtration help to stabilize the slopes or embankments. Through slope classification and geotechnical engineering reports, it can be determined what reinforcement type is needed to prevent landslides. [...] 1. Geogrids
Used for stabilization and reinforcement, geogrids are open, mesh type materials commonly used to reinforce retaining walls or subsoils below roads. Geogrids can be either uniaxial (strength in one direction) or biaxial (strength in both directions) and are used in place of traditional gravel for soil stabilization
1. Geonets [...] 1. Geotextiles
Geotextiles are permeable fabrics used for reinforcement, protection, filtration, drainage and separation, and they are commonly used in conjunction with soil or rock. Geotextiles fall into two categories, woven and non-woven. Woven geotextiles use perpendicular fibers woven to make up a cloth like material. The fibers of non-woven geotextiles are more random and are often made of synthetic polymer.

For landslide mitigation, geosynthetics are often utilized to provide tensile strength and added stiffness to the soil, which is basically strong in compression, to achieve a safe level. Geosynthetic reinforcements combine high tensile strength (up to 1000 kN/m in some products) with limited tensile creep, improved interaction with the surrounding soil material, and resistance to chemical/biological degradation and environmental ageing. [...] ## 2 Geosynthetics for Landslide Prevention
Within the many civil engineering applications where geosynthetics play a fundamental role, their use in landslide stabilization projects is not new. The main related functions for landslide stability purposes are filtration, drainage, protection and reinforcement. Geosynthetics demonstrate several significant mechanical/functional/technical advantages.
Engineers can prevent landslides in various ways using geosynthetics: [...] Layers of geosynthetic reinforcement are used to stabilize slopes against potential deep-seated failure using horizontal layers of primary reinforcement. The reinforced slope may be part of slope reinstatement and/or used to strengthen the sides of earth fill embankments.

Landslides can be controlled by improving drainage conditions, cultivating more vegetation on slopes, providing adequate containment structures, and using some newly developed soil improvement techniques such as soil reinforcement (Shukla 1997; Mohri et al.. 2009; Cuomo et al. al. 2020). [...] Although less used, geotextile tubes to attenuate the wave breaking process in meandering rivers or to fill broken sections of dams have proved to be very suitable as low-crest submerged structures to reduce the energy of waves incident on the banks.

Construction techniques for landslide mitigation include building retaining walls with proper backfilling and compaction, constructing concrete retaining walls with proper reinforcement and contraction joints, implementing soil nailing for reinforced ground zones, utilizing ground anchor walls, installing horizontal drains to reduce water pressure, and seeking professional guidance from engineers specializing in landslide risk mitigation.

After you dig the footings and build the forms, you must add reinforcement, such as rebar. If the wall is higher than four feet, you should pour each footing separately. Allow the concrete to properly cure then create contraction joints. They should be placed every four to six feet. Finally, remove the forms and install waterproofing and the drainage system. To increase slide-resistance, include a footing key.
Soil Nailing [...] Soil Nailing
Soil nailing is a cost-effective way to create a reinforced ground zone. You can use a work platform suspended from a crane to install them on steep slopes like a bluff.

Geomats are anti-eroding biomats or bionets that are purpose-made synthetic products for the protection and grassing of slopes subject to surface wash. Geomats provide two main erosion control mechanisms: containment and reinforcement of the surficial ground; and protection from the impact of the raindrops.
Geogrids made of geosynthetic materials [...] Insertion of reinforcement elements into the ground
The improvement of the mechanical characteristics of the ground through chemical, thermal, or mechanical treatment.
### Insertion of reinforcement elements into the ground
[edit]
Types of mechanical reinforcement include:
Large diameter wells supported by one or more crowns of consolidated, and possibly reinforced earth columns
Anchors
Networks of micropiles
Soil nailing
Geogrids for reinforced ground
Cellular faces [...] formation of any header niche and perforation
setting up of a reinforcement bar (e.g. a 4–6 m long FeB44k bar)
concrete injection of the bar
sealing of the header or of the top part of the hole
Closing up and cementing any cracks in the rock can prevent pressure caused by water during the freeze-thaw cycles from producing progressive breaking in the reinforcement system set up. The procedure for this usually consists of:
