In this application, stronger geosynthetics are required than those used for separation alone, thus the cost of the material is somewhat increased. Bid prices for stabilization geosynthetics are typically on the order of $1.20 to $3.60/m2. Cost tradeoffs should also be evaluated for different construction and geosyn-thetic combinations. This should include subgrade preparation and equipment control versus geosynthetic survivability. In general, stronger, higher survivability geosynthetics will [...] A rapid, first-order assessment of cost items for comparing a flatter unreinforced slope with a steeper reinforced slope is presented in Figure 2. Evaluating the cost as shown in the figure, if the backfill materi-al for a 3H:1V unreinforced slope cost $5/m3, a 1H:1V geosynthetic RSS can be constructed at about the same cost as the 3H:1V slope, and that does not include the cost of the land saved by building the steeper slope. In urban and suburban environments where the land cost is expensive [...] Cost for geosynthetics (i.e., geotextiles or geogrids) in this application typically range from approximately $3/m2 to $15/m2, while the granular fill material typically used for embankment construction ranges from $5 to $20/m3 based on bid prices from geotechtools.org, 2012). The amount of fill saved often offsets the cost of the reinforcement and additional cost savings is usu-ally achieved through expedient embankment construction when using geosynthetic reinforcement (re-viewed in Section

are used to hold down mulch above the seeds. Costs vary with the application. The geonets and webbing range from $0.30 to $1.00 per yd2 • The heavier mats and geogrids range from $1.00 to $5.00 per yd2 • For steeper slopes and highly erodible soils the cost may be justified. There are no sufficient standards for erosion control materials except for geotextiles under riprap since the application has such a short history. Most erosion control systems are still in a trial stage. However, the [...] 1/3 to 1/2 inch thick they are not overlapped. 2 All of these synthetic materials make up 15 to 20 percent of erosion control applications. The primary reason for use of these geosynthetics is better performance with higher flow rates or on steeper slopes. They can also provide for greater erosion protection in the long term then the biodegradable products. Geosynthetics can hold under more severe conditions. They are however more expensive, harder to install, and not as appealing as the [...] to form a grid configuration. The primary function of geogrids are for reinforcement although they are useful for separation as well. Geonets and geomats are flexible geosynthetics that are constructed with large openings like fencing or netting. They are useful in providing drainage of aggregate systems in the case of geonets and in erosion control in the case of geomats. Geomats and nets can also be made into honeycomb structures useful for stabilizing slopes. Geocomposites can be combined of

range of $40/ft2 of vertical height, depending on the site conditions and project requirements. For comparison, MSE walls in Maryland cost approximately $60/ft2 of vertical height. These unit prices are cost estimates for facing, but the cost of backfill must also be considered. They are inflated compared to the average bid price of $33.70/ft2 for MSE facing in Texas. However, if the cost ratio between the two construction methods is similar, GRSS facing in Texas could cost approximately [...] $60/ft2 of vertical height. Interview #5 The respondent has worked for the state transportation agency as a consulting engineer on several reinforced slope projects. He warns that edge compaction is among the most common challenges faced during construction. The engineer recommends geogrid as the primary reinforcement material, although other materials are often used for the slope facing. Geocells provide an alternative approach to the facing that allows a hand compactor to be employed on the [...] minimum of 3 ft in all directions. Florida DOT (2010) Place the geosynthetics used for slope stabilization such that its primary direction of tensile strength is perpendicular to the plan face of the slope. Pull the material tight and secure it as necessary to lay flat against the soil prior to fill placement. Place only that amount of geosynthetic material, including facing and drainage material, which will be covered in a single day’s production. Mississippi DOT (2004) Geogrid shall

Other geosynthetic materials can be used with geocell. It provides a cost-effective, quick, and secure option for protecting geomembrane impermeability material, particularly in pond applications. The valuable filler material in the cell is protected from mixing with the existing low-quality soil when geotextile (separation geotextile) is used in soil reinforcement applications and slope stability difficulties. Water entering the cell is quickly drained through special perforations in the cell [...] ## Geocell Prices
Geocell price is calculated based on the square meter surface area of the material's dimensions when it is opened. The price of geocell is determined by the width, length, and height of the material. The geocell, which is used to stabilize slopes, comes in medium and large sizes while geocell used for ground reinforcement, on the other hand, is quite small.

Geosynthetics are modern materials used to improve soil conditions by providing tensile resistance and stability. In the case of soil reinforcement, a primary application of geosynthetics involves reinforcing steep slopes. With the use of geosynthetics, the construction of reinforced steep slopes is often more affordable and technically feasible when compared to traditional construction techniques . Furthermore, geosynthetic reinforcement is a cost-effective solution for stabilizing recurring [...] Geosynthetics is a crucial mechanism in which the earth structures can be mechanically stabilized through strength enforcing tensile reinforcement. Moreover, geosynthetic reinforcement stabilizes steep slopes through incorporating the polymeric materials, becoming one of the most cost-effective methods in not only accommodating budgetary restrictions but also alleviating space constraints. In order to explicate on the applicability and widen the understanding of geosynthetic reinforcement [...] Many site specific characteristics contribute to the overall cost, including cut-fill requirements, slope size and type, existing soil type, available backfill materials, facing finish, and application. The approximate costs of the principal components are as follows: reinforcement 45–65 percent, backfill 30–45 percent, and face treatment 5–10 percent.

Geotextiles are permeable fabrics that separate, filter, and reinforce soil for erosion control and drainage.
Geogrids are flat, grid-like structures that reinforce soil by distributing loads, common in road bases and retaining walls.
Geocells are 3D, honeycomb-like structures that confine and stabilize soil, ideal for slope stabilization and intense erosion control. [...] Geocells work deeper underground than geogrids. They remain stable in challenging terrain, so they’re good for slope stabilization, erosion control, and riverbank protection projects. They’re especially popular for unpaved roads and parking lots. On paved roads, they strengthen the subbase to allow for a thinner layer of asphalt. [...] These four geosynthetic materials have different designs and applications based on a given project’s stabilization or containment needs. You may find that geosynthetics are the best fit for your project, you may combine them with other methods, or you may find a different soil stabilizer that better meets your needs. The key is to know your options and choose what’s best for your project.
