What is the easiest retaining wall to DIY?
The most simple method of retaining is using a masonry link wall block such as the Adbri Versawall Block. This type of block requires no specific engineering, concrete, mortar or glue. That being said, if you’re planning a large wall (long or high), take your time and DON’T attempt it in just one weekend! A footing is critical for a retaining wall’s stability, even for a 2-foot structure. The footing ensures the wall evenly distributes weight and resists forces from soil pressure, water, and potential shifting.Retaining Walls Can Require a Lot of Maintenance If Not Build Right. This can be costly, and if not done properly, retaining walls can collapse, causing serious damage to property and even injuries or fatalities. They can also become unsightly if they are not kept up with, affecting the curb appeal of your home.The base of a retaining wall should be set below ground level and made from compacted soil and a layer of at least 150mm of compacted sand and gravel. This will ensure that the wall remains flat, meaning more contact between the materials used in its construction, meaning more friction and ultimately more strength.By incorporating a well-designed drainage system, using geotextile fabric, choosing suitable backfill materials, incorporating vegetation and planting, and implementing terracing or staircases when necessary, you can effectively prevent soil erosion and ensure the long-term stability of your retaining wall.Absolutely. Even a 4-foot retaining wall needs proper drainage to prevent structural failure. Water is heavy—about 62 pounds per cubic foot—and when trapped behind a wall, it exerts hydrostatic pressure.
What is the cheapest option for a retaining wall?
Poured concrete is the cheapest type of retaining wall, in terms of materials. Pressure-treated pine is next, and wood retaining walls are becoming more popular now. If you prefer stone, granite is generally the least expensive option. When it comes to cost-effective retaining wall solutions, concrete retaining wall blocks are among the top choices. These blocks are precast, which means they are manufactured in a controlled environment, ensuring consistency in quality and size.Concrete retaining walls are usually considered the strongest due to their durability and ability to withstand heavy loads. They are highly popular for both residential and commercial properties, offering long-lasting support with minimal maintenance.
Does a 2 foot retaining wall need drainage?
Absolutely! Even a 2-foot retaining wall needs an effective drainage system. Without it, water can build up behind the wall, leading to pressure that might cause the wall to lean or even collapse. All walls need systems to manage water effectively, preventing damage over time. Building a retaining wall costs $35 to $65 per square foot on average, including the materials and professional labor. The total cost depends on the location, site conditions, and the wall type, material, length, and height.
