Wall-to-Wall Article Summary
Retaining walls stabilize slopes, reduce erosion, direct runoff and create usable space, helping land development and infrastructure projects build safer, long-lasting stormwater management systems.
Urban and regional planners trust MagnumStone retaining walls to protect community roads, homes and public infrastructure from the risk of flooding, erosion and damage caused by severe storms.
MagnumStone’s proven stormwater management solutions continue to replace aging infrastructure worldwide and build new communities with modern, future-focused design considerations.
Retaining Walls: More Than Just Structural Support
Traditional retaining walls are thought of as concrete blocks that hold back soil and create usable space on sloped properties. While retaining walls certainly serve this critical function, they also play an increasingly important role in modern stormwater management strategies.
Communities, now more than ever, are continuing to grapple with the challenges associated with urban development, increased runoff and erosion. Extreme weather events have driven innovative construction, with retaining walls now a prominent building material that handles wide-ranging, complex applications.
MagnumStone’s engineered precast retaining walls have designed and built exemplary solutions for these purposes, successfully managing stormwater to protect communities. Their durable reinforced designs have become valuable tools, controlling and containing water and erosion for residential, commercial, and infrastructure projects.
Understanding the Challenges Caused by Stormwater
Developing natural landscapes means permeable surfaces such as forests and grasslands are often replaced with roads, parking lots, sidewalks, and buildings. These harder surfaces prevent water from infiltrating directly into the ground, increasing the volume and speed of stormwater runoff.
The transformation of these environments goes beyond how the properties look and are used. Today’s land development projects require more strategic planning for critical design considerations. Without proper management, altering these environments can lead to major stormwater issues, most commonly causing:
- Flooding and soil erosion
- Slope instability
- Damage to infrastructure
- Sediment pollution in waterways
- Increased maintenance costs
Effective site design addresses where the water comes from, but more importantly, where the water is going. MagnumStone’s engineered retaining wall systems offer proven solutions, from water containment ponds to riverbanks and canals that safely redirect stormwater.
The Importance of Retaining Walls in Stormwater Management Solutions
There are many factors required to build effective stormwater management systems to capture, control, convey and safely handle runoff. Retaining walls have become essential components for managing stormwater, especially precast block systems like MagnumStone. Precast concrete is water-resistant and can last generations in severe weather conditions, withstanding hurricanes, preventing landslides and coastal seawall exposure.
These retaining walls can proactively help minimize property damage or help expedite safe post-storm reconstruction. It’s important to note that stormwater damage doesn’t always happen suddenly due to major rainfall events. Annual snowmelts and continuous everyday runoff can gradually be as destructive over time, especially without adequate infrastructure, support or maintenance.
The main functions of retaining walls include (but are not limited to):
- Controlling Slope Erosion
Retaining walls stabilize slopes by creating terraces and reducing runoff velocity, helping minimize erosion. - Managing Water Flow
Properly designed retaining walls can help safely direct stormwater toward swales, storm drains, detention ponds, retention basins, infiltration systems and rain gardens. - Creating Space for Stormwater Infrastructure
While retaining walls maximize usable land, they can build permanent water storage areas, like retention ponds, or help dry ponds blend into parks and public spaces. - Supporting Sustainable Drainage Solutions
Modern hollow core retaining wall systems are filled with crush gravel to allow faster drainage and help reduce hydrostatic pressure behind the wall.
MagnumStone’s diverse retaining wall solutions easily handle these challenges, with several engineered designs to achieve project goals and purposes. Stormwater retention y detention ponds help provide permanent or temporary containment options that can subtly blend into communities. They build exceptional riverbanks, streambanks, conveyance channels y eco-friendly bioretention ponds.
Why Retaining Wall Drainage Matters
One of the most consistent reasons for retaining wall failures is excessive water buildup behind the structure. This increases hydrostatic pressure and can lead to movement, bulging of the wall, or complete wall failure – all costly results.
With 100-year storms occurring more frequently, engineered retaining walls must consider these scenarios as critical factors for modern infrastructure designs. In the past, engineers questioned where water was coming from. Now, retaining wall designers have shifted to a proactive approach.
One key question continues to circle back, centering on the importance of drainage:
“Where is the water going?”
Today’s retaining wall designs account for the following drainage considerations and site challenges:
- Drainage aggregate to help filter debris and sediment
- Perforated drain tile systems to guide and direct water
- Planned designs for capturing surface water collection
- Sufficient outlet locations along the retaining wall
- Site grading that conveys water to safe areas and storm drains
- Maintenance and access to ensure unimpeded drainage channels
Retaining Walls in Municipal and Infrastructure Applications
The water-resistant nature of precast retaining walls helps bolster the effectiveness of stormwater management systems in large communities and rural neighborhoods. They complement and fit into their natural surrounding landscapes, serving crucial purposes but are generally overlooked by the public.
These can be hidden in plain sight as human-constructed lakes, grading and swales along athletic fields, and other applications. Typical retaining wall stormwater management are strategically built for:
- Highway embankments and erosion management
- Bridge approaches and road widening projects
- Flood control and stormwater capture facilities
- Utility corridors, railways and road washouts
- Public parks, pathways and recreation facilities
The Future of Water Management and Retaining Walls
As stormwater regulations and infrastructure design requirements continue to evolve, retaining walls will play an increasingly important and integrated role. Retaining walls are not simply structures that hold back soil, they are essential components of comprehensive stormwater management strategies.
MagnumStone’s precast retaining wall system offers proven stormwater management and erosion control solutions for residential, commercial and infrastructure projects. From simple to sophisticated, these walls can withstand any conditions, from gradual runoff to severe weather and coastal climates.
