Installing a retaining wall can give your landscape a makeover in terms of functionality and beauty. But it’s not as easy as piling up blocks; there are a few traps that DIYers and even some professionals may fall into. At Hernandez Lawn Care, we have witnessed it all, particularly in the retaining wall market in Chicago. Let’s discuss some common errors and how you can steer clear of them.
What is a Retaining Wall?
A retaining wall is a man-made structure that “retains” or holds back soil. Retaining walls are typically used to prevent soil erosion or to level sloped terrain, creating more usable space. Depending on your soil and the degree of sloping in your yard, a retaining wall might be an important structural part of your landscaping.
Common Mistakes when installing retaining walls and how to avoid them
Let’s dive into the common mistakes people make while installing retaining walls and how you can avoid them for a smooth installation.
- Bypassing the Permitting Process
Why It’s a Mistake:
Homeowners want to begin their project quickly and forget to acquire the proper permits. This results in legal trouble and possible fines.
How to Avoid It:
Always consult with your local municipality regarding permits necessary prior to commencing construction. This makes sure your wall is in compliance with local regulations and building codes.
- Poor Planning and Design
Why It’s a Mistake:
Leaping into a building without a clear plan can lead to a wall that doesn’t function or, worse, structurally fails.
How to Avoid It:
- Analyze the Site: Know the soil condition, slope, and drainage patterns.
- Design Accordingly: Take into consideration the height, length of the wall, and the load it must support.
- Consult Experts: For complicated projects, take expert advice from professionals.
- Selecting the Wrong Materials
Why It’s a Mistake:
Not all materials work for all projects. The wrong type can undermine the integrity and appearance of the wall.
How to Avoid It:
- Research Material Options: Materials such as concrete blocks, natural stone, and timber are common.
- Consider Durability: Select a material that can handle Chicago’s weather.
- Aesthetic Appeal: Choose materials that fit into your current landscape.
- Failure to Properly Drain
Why It’s a Mistake:
Water build-up behind the wall causes hydrostatic pressure, resulting in bulging or collapse.
How to Avoid It:
- Install Drainage Systems: Add drain tiles or weep holes to let water drain.
- Use Permeable Backfill: Gravel and other materials allow water to flow away from the wall.
- Poor Foundation Preparation
Why It’s a Mistake:
Weak foundation will make the wall lean or settle crookedly in the future.
How to Avoid It:
- Excavate Properly: Dig a trench that is suitable for the size of the wall.
- Use Quality Base Material: A stabilized gravel base ensures stability.
- Ensure Leveling: A levelled foundation is the key to a long-lasting wall.
- Disregarding Soil Characteristics
Why It’s a Mistake:
Soils have different load-bearing capacities and drainage characteristics.
How to Avoid It:
- Do Soil Tests: Identify the nature and stability of your soil.
- Make Adjustments Accordingly: Adjust the design of the wall in accordance with the soil conditions, possibly including reinforcement.
- Forgetting about Reinforcement Needs
Why It’s a Mistake:
Taller walls or those that are subject to extra loads can be reinforced to ensure structural integrity.
How to Avoid It:
- Utilize Geogrid Materials: These can add stability to taller walls.
- Adhere to Engineering Guidelines: Make sure the reinforcement is to the required specifications for your project.
- Inadequate Backfilling Practices
Why It’s a Mistake:
Incorrect backfill material or failure to compact it can cause settling and instability.
How to Avoid It:
- Choose Proper Backfill: Employ granular materials such as gravel.
- Compact in Layers: This avoids future settling and ensures wall stability.
- Building Without Batter
Why It’s a Mistake:
Building the wall straight up without a slight backward lean (batter) can diminish its capacity to resist soil pressure.
How to Avoid It:
Add a Batter: A 1-inch setback per foot of height is usually advisable.
- Trying Complex Designs Without Expertise
Why It’s a Mistake:
Intricate designs can be challenging and, if not executed correctly, may lead to structural issues.
How to Avoid It:
- Start Simple: For DIY projects, begin with straightforward designs.
- Hire Professionals: For complex projects, it’s best to consult or hire experienced contractors.
How to Avoid These Mistakes
- Educate Yourself: Before starting, research and understand the basics of retaining wall construction.
- Consult Professionals: When in doubt, seek advice from experienced contractors.
- Use Quality Materials: Spend on materials that are appropriate for your particular project requirements.
- Practice Best Practices: Comply with established standards and local building regulations.
