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 walls are commonly referred to as gravity walls, reinforced walls, or reinforced soil slopes. The 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. The GEOWEB walls conform well to landscape contours, are resistant to environmental degradation, and install 25-30% faster than MSE block walls.

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.

Today’s increasingly stringent environmental regulations continue to create the need for Low Impact Development (LID) and Green Infrastructure (GI) management on project sites. New and innovative methods must be used to limit hard surfaces such as parking lots, walkways, and emergency access lanes. Land access is at a premium, and areas of environmental protection are increasing, requiring builders and engineers to work with regulators to utilize both LID and GI practices. Porous pavements are an easy and economical way to reduce the impervious surfaces on-site and restore the natural water cycle close to its source. Porous pavements have the added benefit of reducing the size of above-ground detention ponds and minimizing conveyance and treatment infrastructure. Stormwater diversion channels, roadside swales, and drainage ditches can be constructed with low-maintenance solutions, protecting against erosion and overflow concerns. Living green walls increase the amount of vegetation on-site, help promote water filtration from higher elevations, and allow access to more valuable land. Learning Objectives: Learn what Low Impact Development and Green Infrastructure mean for residential and commercial project sites. Gain an understanding of the regulations governing these practices and how they have been met with traditional construction methods. Learn about porous pavement options and… Read more »
Today’s increasingly stringent stormwater regulations continue to create the need for stormwater management. The preferred method is to retain the stormwater on-site rather than having it move off-site through overland flow or into storm sewers. Typical solutions—retention or detention ponds—are expensive to construct, occupy valuable land, require significant maintenance, can be safety hazards, and are unattractive nuisances. An alternative solution is to reduce the amount of impermeable surface on the site. Hard-surface (asphalt and concrete) porous pavements are expensive and can be very difficult and time-consuming to install. Rigid and flexible plastic porous pavement systems provide a low-cost, easy-to-install surface designed to handle the most demanding load requirements. The porous pavers from Presto Geosystems can have a vegetated or aggregate infill. Learning Objectives: Understand the benefits of porous pavements. Learn how the rigid and flexible porous pavements perform under varying infill materials and traffic-loading conditions.
