Case Studies

Infrastructure development for highways and road corridors faces many challenges when it comes to project design and construction. Building asphalt or concrete roadways over soft soils requires thick base layers of expensive stone, and pavement surfaces often fail just a few years after installation. Expanding road width requires steepening corridor embankments, leading to potential slope failure that can cause road closures and damage. Stormwater management alongside roads is an increasingly common concern due to limited construction space and larger storm events. Presto Geosystems provides cost-effective, low-maintenance, quality solutions for all of these potential issues using our GEOWEB® 3D Soil Stabilization System. In this webinar, we will discuss how to utilize these solutions to address the challenges of aging infrastructure. Learning Objectives: • Gain an understanding of the innovative ways Presto Geosystems’ products can provide permanent stability solutions along roadways and surrounding areas. • Understand how geocells perform in the most challenging soil conditions. • Learn about different geocell applications and where they can be used in roadway corridors. • Learn how to use geocells to help manage stormwater runoff alongside roads and prolong pavement life.

The energy sector is faced with many challenges when it comes to project design and construction. Many times access/construction roads need to be built over soft, wet soils and must be able to support very heavy loads. Touch and step hazards abound at electrical substations. Pipelines can traverse over hilly/mountainous areas where slopes need to be stabilized after construction is complete. As in all construction projects, stormwater needs to be managed. Presto Geosystems can provide cost-effective, low-maintenance, quality solutions for all of these potential issues using our GEOWEB® 3D Soil Stabilization System (Geocells) and GEOTERRA® Construction Mats. This webinar will explore the solutions and services that are available through Presto. Learning Objectives: Learn about the development of geocell technology, the general applications where it can be used, and the different installation accessories available. Understand how geocells can be useful in energy sector applications, specifically in load support, channel protection, and slope protection. Learn how geocells can eliminate touch and step hazards while still providing stable work surfaces. Gain an understanding of the variety of applications GEOTERRA mats can be used for on construction sites–temporary and permanent use. Learn about successful energy projects using the GEOWEB geocells and GEOTERRA Construction Mats.

In this webinar, we will explore solutions to a number of challenges faced by the mining industry. We will discuss how the GEOWEB®  3D Soil Stabilization System offers a better approach to soil stability challenges when accessing sites over soft ground; controlling and containing stormwater; protecting geomembranes from basins, tailing, and heap leach pads; and reclaiming slopes at the time of closure. Through 3D confinement and the strengthening of infill, less material is required and on-site waste rock can be used. The GEOWEB system offers increased speed of operation, lower maintenance, safer installation, and lower total cost of ownership. Learning Objectives: Understand the benefits of geocellular confinement for high-performing, long-lasting mine infrastructure. Explore mine applications for geocells in haul road, slope, channel, and containment pond solutions. Learn how 3D geocellular confinement can produce higher performance and lower maintenance mine site solutions.

Retaining wall systems are used to hold back earth and achieve grade separation between two adjacent points at different elevations. There are many types of retaining wall systems, including concrete, steel, gabions, sheet piling, and reinforced soil. The GEOWEB® Retaining Wall System, in general, belongs to the reinforced soil category. Depending on the slope angle and site conditions, retaining wall systems are commonly referred to as gravity walls, reinforced walls, or reinforced soil slopes. GEOWEB retaining walls make it possible to stabilize soil at the face of the wall or slope with a naturally vegetated fascia. The GEOWEB system’s open-celled terraces create a natural environment for sustainable vegetation and allow stormwater infiltration. GEOWEB walls conform well to landscape contours, are resistant to environmental degradation, and install 25-30% faster than MSE block walls. Learning Objectives: Learn about the different types of retaining wall systems that can be built with the GEOWEB system. Understand the design of the GEOWEB Retaining Wall System. Learn how the features of the GEOWEB retaining walls and what sets them apart from other types of walls. Learn about the free design tools and software offered by Presto Geosystems.

When paved and unpaved roadway surfaces are built over weak subgrades, base deterioration can lead to degradation. This causes unwanted deflections, rutting, and cracking in the surface layer. Using the GEOWEB® 3D Soil Stabilization System reduces the vertical pressure on roadways and provides a high-stiffness foundation. This increases the load capacity of the subgrade allowing it to more effectively handle heavy and repeated vehicle leads. In the base layer under hard pavements, confinement of aggregate significantly reduces movement and settlement, increasing the life of the pavement. Unpaved roadways also benefit from a more stable surface that performs as an on-site stormwater “detention” basin, promoting infiltration at the source and reducing runoff. Learning Objectives: Understand the benefits of using the GEOWEB Soil Stabilization System to stabilize surfaces for unpaved roads using low-quality fill. Discover how 3D-confined base material reduces cross-section and provides a more stable base, especially over soft subgrade soils. Learn how the GEOWEB system reduces vertical pressure and subbase movement. Learn how to design pavement that will help meet on-site stormwater regulations and low environmental impact goals.

Presto offers its free GEOWEB® MSE design software for gravity and reinforced wall applications. Create vegetated and non-vegetated MSE structures based on the GEOWEB® system inputs for reinforced slopes, and gravity and reinforced walls. The software is based on industry-standard design methods and contains specific algorithms that capture the unique interaction between the GEOWEB® system, retained, foundation, and reinforced soil, specific factors of safety, and geogrid reinforcement, if applicable. In this webinar, we will provide an in-depth tour of the MSE wall design software.

Earthen slopes are naturally susceptible to erosion due to gravity, water, and surcharge loads. Slope failure can lead to unsightly conditions, landscape and property damage, and costly repairs. The GEOWEB® 3D Soil Stabilization System protects soil slopes against these erosive forces. Even extremely steep or tall slopes can be secured with the GEOWEB system. Multiple types of infill and anchoring methods allow for project customization, resulting in a low-maintenance and attractive slope for years to come. Learning Objectives: Understand the causes of slope surface erosion and how they lead to slope failure. Learn how the GEOWEB system can protect slopes against erosive forces. Learn how to apply GEOWEB Slope Protection Systems in a variety of project conditions. Know when the GEOWEB system is applicable, even on very steep slopes.
