Get matched with top retaining wall installation pros in Cascade, WI

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

The lifespan of a retaining wall varies based on its material, installation quality, maintenance, and local climate, with an average range of 20 to 100 years. Retaining walls made from durable materials like concrete, stone, and brick generally last a minimum of 50 years. Concrete walls typically last between 50 and 100 years, while brick can last for over a century in ideal conditions. Timber retaining walls can last from 20 to 40 years, depending on the wood quality, and pressure-treated wood walls average around 30 years. It is important to note that a retaining wall can fail prematurely if it was poorly constructed, for example, with inefficient footings or without necessary rebar reinforcements.
