What Is a Retaining Wall?
The pressure behind a retaining wall, holding back tons of soil and water, can be enormous.
Considerable knowledge and experience are needed before undertaking such a project.

Research local building codes, especially if erosion and runoff are concerns.
It takes roughly 20 to 30 hours, depending on multiple factors.
Significant runoff issues will require professional assistance.

Do not overlook the aesthetic component of retaining walls.
Select a material that is in sync with your overall design goals.
Retaining walls made of materials other than concrete retaining wall blocks requires the assistance of a professional.

In contrast, a 2-foot-tall steel or stone retaining wall can cost about $200 per linear foot.
So, a 10-foot-long, 3-foot-tall wall will cost roughly $1,200.
Shoveling dirt and gravel can be hard on the back.

Check with your carpenter’s level to ensure that it is level, both left-to-right and front-to-back.

Because this will necessitate having half-blocks at each end, you musthave a tool on hand for cutting blocks.
Continue to lay courses that are perfectly level, with staggered joints, until the necessary height is reached.

How Is a Retaining Wall Used?
But you are underestimating the possibilities for these structures if you see them only as erosion fighters.
Consider changing your property’s “lay of the land” when erecting a retaining wall.

Use the terraces to show off eye-opening flower beds.
But anything taller should be left to professionals.
Also, any significant runoff issues in your area require an expert with a strong understanding of engineering considerations.

How Often to Replace a Retaining Wall
A retaining wall should last between 25 to 100 years.
However, you oughta maintain it to expect longevity.
The key to maintenance is routine inspection.

Remove any rocks or debris that may block drainage pipes (if you have them).
If soil erodes behind the wall, leaving gaps, fill those spots with fresh soil.
Pooling water can erode the concrete blocks.
Look for cracks or shifting blocks.
Also, pay attention to any bulging or bowing of the wall.
Contact a professional for assistance remediating any damage.
Tip
Consider using plantings behind the wall.
Plant roots help keep the soil in place, reducing erosion.
If the plants die in winter, replace them in the spring.
Not all retaining walls need a footing.
For example, interlocking retaining walls don’t need it.
