What Is The Best Size Footing For A Concrete Retaining Wall?

The depth of the foundation slab should be kept to a minimum of two feet. The seasonal frost line may be substantially deeper in northern places. As a result, it’s critical to keep it below that level at all times.

The length of the foundation slab is typically between 50 and 70 percent of the whole wall height (bottom of base to top of the stem).

The stem thickness at the base of cantilever and counterfort walls, like the thickness of the foundation slab, is normally 10% of the entire wall height. For counterfort retaining walls, at least 30% to 70% of the total wall height is necessary.

In some cases, a footing key may be included as a safety measure to prevent slippage. In general, the footing key extends below the base’s bottom.

What Are The Specifications For A Concrete Retaining Wall?

A functional retaining wall must have an exit for the water that gathers behind it. Without a pressure-relief device, the wall would crack or bow if not supported by the soil.

Some water drains through weep holes, 3/4-inch pipes constructed along the top of the first course. Another component of the system is the gravel-coated plastic drainpipe.

Water seeps through the wall and flows through the gravel into the drainpipe, where it is safely evacuated.

The strength criteria for freestanding walls are not the same as those for retaining walls. Following a three-block spacing, insert rebar in your footings as required by your local requirements. At this step, ensure that all the rebar is coated with mortar.

Why Is Concrete Preferred Over Other Materials For Retaining Walls?

Concrete retaining walls are less expensive to build than natural stone ones. Concrete retaining walls may also be constructed more quickly due to their lesser weight. Concrete retaining walls need less work effort.

Concrete, which is suited for both residential and commercial establishments, allows you to include a broad choice of colors and designs into your design.

Concrete retaining walls are extremely long-lasting. Their elasticity and compressive strength outperform block walls.

Non-toxic concrete retaining walls do not produce hazardous chemicals or cause allergies. Concrete wall construction uses a significant quantity of recycled or locally generated natural resources, such as clay, limestone, fly ash, and slag.

How Can I Give My Concrete Retaining Wall A Textured Appearance?

Applying a layer of stucco to your concrete retaining walls can give them a textured aspect and make them more attractive.

Attach little slabs of smooth, natural stone to the wall top as a “cover” using the appropriate glue.

Stucco may help a concrete wall retain less moisture and absorb moisture more quickly in a variety of ways.

Stucco can be used to cover a concrete wall. However, any old paint must be removed first.

This may be accomplished by putting stucco on the exterior of the concrete wall. If desired, you may cover the top of the wall with smooth, natural stone slabs using the appropriate adhesive.
