What Are The Biggest Mistakes People Make When Building Retaining Walls? Key Takeaways Conduct a thorough site assessment before building a retaining wall. Evaluate soil composition, drainage patterns, and the slope of the land to ensure stability and long-term performance. Most importantly, be sure to follow local building codes and get the appropriate permits. Not only does this protect against legal risks, but it ensures that the structure is built to safety standards. Proper drainage is essential to prevent hydrostatic pressure from water buildup behind the wall. Use fabric filter cloth. Install the wall backfilled with adequate granular material. Provide several drainage outlets to keep pressure from building up behind the wall. Buy the best materials you can afford that are right for your application. Using substandard or mismatched materials is a recipe for structural failure and constant maintenance. Adhere to proper installation practices, like compacting the base, leveling the first course, and giving yourself enough time to backfill. Once you start building, rushing the process could lead to mistakes that could hurt the integrity of the wall. Regular maintenance, including inspections and addressing early warning signs, is essential to keep the retaining wall safe and functional over time. The biggest mistakes people make when building retaining walls come from a lack of planning. They make mistakes by selecting the wrong materials and installing improper drainage systems. Poorly prepared walls can compromise the protection they’re meant to offer and cause even more serious structural problems or even the wall’s collapse. Using poor quality or incompatible materials, such as untreated wood or undersized blocks, can make a wall vulnerable to failure. Ignoring water drainage is a third all too frequent mistake because trapped water adds unwanted pressure and makes walls unsteady. These mistakes can be the difference between having a wall last for decades and one that will require expensive repairs or even replacement. Avoiding these common mistakes is key to building a safe and durable retaining wall. In the next post, we’ll go through each of these mistakes in-depth and discuss how to patch the leaks before it’s too late. Planning Pitfalls: Setting Up For Failure Smart planning is key to ensuring you’ll end up with a stable, long-lasting retaining wall. Yet, far too often, we skip important individual steps during the early phases. From overlooking soil compaction to avoiding required environmental permits, these mistakes can result in expensive rework or, worse, compromised structural integrity. Here, we outline frequent planning pitfalls and how they can set planners up for failure. Skimping On-Site Assessment Comprehensive due diligence is important. Ignoring important natural drainage patterns can lead water to collect behind the wall, building up pressure and potentially leading to failure. For instance, not realizing the wall is built over a natural drainage path could lead to re-routing water directly to the wall’s foundation. Analyzing environmental conditions such as invasive tree roots nearby is just as important to prevent having the structure interfered with in the future. Commissioning and documenting these details helps to make sure the wall works with the site instead of against it. Ignoring Soil Composition Soil type plays a huge role in how a wall will perform. Clay soils can expand when saturated, leading to movement. Sandy soil does not have enough load-bearing capacity. By taking moisture content predictions into account, future environmental conditions can be avoided, thus precluding deleterious conditions such as soil erosion or settling. When this crucial step is avoided, stronger foundations are significantly weakened. This is even more the case when the ground isn’t layered in compaction or when unknown recycled substances act as the base. Miscalculating Wall Dimensions We can’t stress enough how important accurate dimensions are. Too short of a wall will not meet the required drainage needs, and too high of a wall without sufficient structural support can create dangerous instability. On sloped land, modifying the width and length keeps all the weight evenly distributed. Poor understanding of material weight, such as choosing blocks that are too large to support the overall structure, can lead to structural misalignment. Overlooking Local Building Codes Ignoring codes, no matter how well-intentioned, sets you up to get hit with fines or even forced rebuilding. Just as wall height is limited, many communities require specific wall materials to combat this type of construction. Foundations and walls in colder climates need to account for the frost line to avoid freeze-thaw damage. Failing to secure required permits can further slow projects or increase safety dangers. Drainage Disasters: Water’s Destructive Power Water is undoubtedly the greatest enemy to the strength and stability of a retaining wall. Inadequate drainage design or maintenance practices can worsen water accumulation, resulting in hydrostatic pressure. This pressure pushes inward against the wall, contributing to potential structural failure. Up to 90% of retaining wall collapses are attributed to drainage failures. This highlights the absolute necessity of getting drainage right in the first place when working on roadway construction. Neglecting Backfill Material The material selected for backfilling is extremely important. Gravel or crushed stone is best as these materials promote drainage and help relieve soil pressure. Stay away from organic materials such as topsoil or mulch because when these decompose, they leave voids, compromising the integrity of the wall. Compaction is just as critical. If the backfill is poorly compacted, pockets of water will form, putting more pressure on the wall. A layer-by-layer compaction strategy is key to providing a solid foundation, maximizing compaction, and mitigating dangerous failure points. Forgetting The Filter Fabric Keeping filter fabric clear is critical to ensuring proper drainage. Durable fabric in the sleeve keeps loose soil from filling up the drainage system but lets water move through. Without it, clogged drains leave no path for the water to escape, allowing it to pool and eventually burst through the wall. Routine inspection is important to make sure the fabric is doing its intended purpose of keeping the embankment safe and sound, particularly in areas subjected to significant rain events.
