Retaining Wall 101

Homeowners who want a strong, versatile, and aesthetically appealing structure should select this option.

Retaining walls prevent soil erosion on a property. They can also be used to beautify an outdoor space. However, this depends on the construction. Retaining walls help to hold back the earth for homes built on a slope.

Let's discuss the different types of retaining walls, their pros and cons, and considerations when installing them.

Concrete block retaining walls

Homeowners who want a strong, versatile, and aesthetically appealing structure should select this option. The blocks feature various locking wall systems. Homeowners should select a wall system that helps to create the desired appearance. Concrete block retaining walls are suitable for large-scale projects. They are durable and offer excellent stability. But, these retaining walls have their limitations. Most notably, they are costly and labor-intensive.

Sandstone log retaining walls

If one needs something functional yet stylish, consider sandstone. Sandstone block retaining walls make a perfect choice. They're easy to install and maintain. These retaining walls are also budget-friendly.

Stone retaining walls

Stone retaining walls can be set up using wet or dry stones. Their interlocking structures help to create a beautiful and elegant look. Homeowners should hire skilled contractors for the best results.

Other factors

Homeowners planning to install retaining walls should consider a few essential factors:

Support

Retaining walls should be angled toward the earth they're trying to contain. This helps to minimize the pressure from the eroding soil. Find out whether the retaining wall selected requires additional support. It helps to ensure that the retaining walls don't fall.

Foundation

The base of the retaining walls depends on its height and size. Filling the trench with gravel is enough when dealing with short walls. Larger retaining walls require buried footings for adequate support. Homeowners should consult the local building authorities for advice on this.

Drainage

Unlike stackable retaining block walls, solid structures require drainage provision. Installing drainage tiles helps to direct excess water away from the retaining walls. This is necessary because if the water collects, it can cause the retaining walls to crack.

Backfill

Gravel or sand is suitable for filling the area behind a retaining wall as they don't absorb water. This ensures the structure isn't pressured, minimizing the chances of cracks and damage.

Protect the home

Soil erosion can weaken a home's foundation. This is common for houses built on slopes. Retaining walls hold the earth back and flatten the ground, ensuring the soil isn't swept away. These walls protect the home from direct impact if the soil tumbles. Homeowners should find the right contractor to supply suitable materials. This ensures that the constructed retaining wall is of high quality.
