The GEOWEB® Retaining Wall System delivers exceptional versatility and performance. Unlike rigid mechanically stabilized earth (MSE) wall systems, GEOWEB walls adapt to soft soil environments, seismic conditions, and differential settlement, while conforming naturally to landscape contours. They can be constructed as gravity walls, reinforced walls, or even reinforced slopes and the flexible nature of the system typically installs 25 – 35% faster than traditional rigid systems. Each wall is manufactured from virgin high-density polyethylene (HDPE), ensuring long-term resistance to environmental degradation.

GEOWEB walls feature horizontal terraces with exposed fascia cells that can be filled with topsoil to support sustainable vegetation and promote stormwater infiltration. Where vegetation is not desired, aggregate or concrete infill can be used to enhance durability and provide additional protection.

Learning Objectives:

• Understand the differences between GEOWEB Retaining Walls and reinforced slopes.
• Explore GEOWEB gravity and reinforced wall systems, including real-world project case studies.
• Identify the unique features and benefits that set GEOWEB Retaining Walls apart from other wall types.
• Gain insight into the design principles for GEOWEB systems across various wall types, reinforcement options, applications, and site conditions.
• Learn how to use GEOWEB MSE, a free design software provided by Presto Geosystems, for walls and reinforced slopes.

When extreme weather events occur, communities are often left to grapple with the devastating effects. An increase in extreme weather patterns, coupled with aging or inadequate infrastructure, amplifies the often dangerous and costly damage that ensues—especially for vulnerable communities living in low-lying areas.

In this webinar, we will discuss how to incorporate GEOWEB® geocells into projects to create climate-resistant infrastructure in load support, slope stabilization, channel protection, and retaining wall applications. The discussion will include solutions for an array of industries, including energy, transportation, and stormwater management. Project case studies will show how this advanced geosynthetic technology can be used for rebuilding storm-ravaged roads, repairing and stabilizing channel embankments, and preventing flooding after extreme weather events.

Learning Objectives:

• Gain an understanding of the innovative ways the GEOWEB® geocells can provide permanent stabilization solutions for a variety of applications.
• Understand how geocells perform in the most challenging soil conditions.
• Learn about projects using the GEOWEB® geocells to improve infrastructure resilience.
• Learn how the GEOWEB® geocells can help manage stormwater and mitigate flooding.

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® 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 loads.

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 pavements that will help meet on-site stormwater regulations and low environmental impact goals.

Commercial truck parking lots face some of the harshest conditions in pavement design: heavy loads, long dwell times, constant turning, and soft subgrades. Traditional asphalt and aggregate designs often fail early, creating costly repairs, downtime, and stormwater challenges.

In this webinar, Bryan Wedin, P.E., Chief Civil Engineer at Presto Geosystems, will explain how the GEOWEB® Soil Stabilization System delivers long-term performance for paved and unpaved truck parking lots. Originally developed with the U.S. Army Corps of Engineers, the GEOWEB geosynthetic system has been proven worldwide for more than 40 years in ports, distribution centers, and other heavy-duty applications.

Attendees will learn how the 3D honeycomb structure reinforces the base layer, reduces pavement and base depth requirements, and creates stable, resilient truck parking areas that drain better and last longer.

Learning Objectives:

• Identify common causes of premature failure in commercial truck parking lots and how they impact long-term maintenance costs.
• Understand how GEOWEB® geocells function as a geosynthetic soil stabilization system that confines aggregate and distributes heavy truck loads.
• Compare performance and cost benefits of geocell-reinforced bases versus traditional pavement and aggregate designs.
• Evaluate design options for permeable and impermeable truck parking lots that address stormwater management requirements.
• Apply lessons from real-world projects in ports, distribution centers, and truck parking facilities to future designs.
