Channels subjected to high flows and associated shear stresses are susceptible to washout of natural soils and rock, which leads to uncontrolled water movement and further degradation. Typical riprap and concrete protection can be expensive and difficult to install. The GEOWEB® channels may be designed with a variety of infill materials to meet aesthetic requirements and resist anticipated hydraulic flows and associated stresses. The GEOWEB® Channel Protection System provides a variety of economical and flexible protection treatments for open channels and hydraulic structures. The system delivers stability and protection for channels exposed to erosive conditions ranging from low-to-high flows—either intermittent or continuous. The GEOWEB system, which can be filled with topsoil, aggregate, or concrete, lowers costs for stormwater control by utilizing on-site materials and eliminating the need for internal reinforcement. GEOWEB channels can withstand high-velocity flow over long channels, and the ability to incorporate energy dissipation allows the GEOWEB system to successfully perform when applied along steep slopes. Learning Objectives: Understand the benefits of GEOWEB channel protection from accredited research and testing.

The constant weight of parked trailers, stacked containers, and heavy traffic patterns can cause your intermodal or port facility yard’s surface and subbase materials to degrade. This instability of the base materials causes rutting, potholes, and even pavement failure. These surface problems can require costly maintenance, and significant interruption of facility operations, as well as create a loss of income from usable space. The GEOWEB® system reduces the vertical pressure and provides a high-stiffness foundation, increasing the load capacity of the subgrade to more effectively handle heavy reach stackers and container loads. In the base layer under hard pavements, confinement of aggregate significantly reduces movement, lateral heave, and settlement for increased pavement life. For unpaved surfaces, the GEOWEB system solves surface stability problems with less aggregate and less maintenance even allowing sand or on-site, lower quality aggregate to be used as infill. Learning Objectives: Understand the benefits of using the GEOWEB 3D Soil Stabilization System on surfaces and pavements. Learn how the GEOWEB system reduces vertical pressure and subbase movement. Understand how the GEOWEB system can reduce pavement depths. Learn how the GEOWEB confinement system extends pavement life and reduces maintenance.

Trails and greenways play a vital role in communities by preserving and creating open spaces for low or no-cost outdoor recreation. Trails designed with permeable surfaces rather than traditional concrete or asphalt allow for better environmental and stormwater management. Since recreational trails can be designed for a wide range of uses, including motorized and non-motorized traffic, it’s important to utilize a solution that is durable and flexible. In this webinar, we will explore a variety of soil stabilization and porous pavement products that can be tailored to the needs of individual projects—including those with hard-to-access areas and stormwater concerns. Multiple types of infill and anchoring methods allow for project customization, resulting in low-maintenance and attractive trails for years to come. Trail embankment stabilization is another consideration when designing recreational trails. The embankments may be part of the existing natural terrain or result from cuts made to accommodate the construction of the new trails. Depending on embankment steepness, the GEOWEB® 3D system can be used to stabilize slopes with single-layer protection or near-vertical, tiered retaining walls with a vegetated fascia. GEOWEB green slopes and walls protect against erosion, reduce stormwater runoff, and create a natural environment for sustainable vegetation. Learning Objectives:… Read more »
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.

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.
