What Is The Purpose Of A Retaining Wall?

Just remember that there is little room for error in designing a retaining wall that will hold back tons of earth and sand.
How Much Does A Retaining Wall Cost?
It starts at $4.30 per square foot for cast-in-place concrete, $5.65 for interlocking concrete block, $6.15 for pressure-treated pine, and about $11 for stone. Installation costs and accessories such as drainage stones and filter cloth are not included.
What Is The Lifespan Of A Retaining Wall?
Wood can last up to 40 years. There is no limit to the lifespan of a properly installed masonry or concrete wall.

With adequate drainage, stone, brick, and concrete block walls are strong and durable. You can buy these materials at a stone store or home improvement center, but you will likely need masonry to install them. Mortar walls rest on a reinforced concrete foundation below the frost line and require drainage holes to relieve earth pressure. Dry stone retaining walls without mortar requires only crushed stone bedding.
Cost. Fieldstone, $11 per square foot (uninstalled), stone yard.
Concrete is the strongest and most durable and can be molded, stained, veneer, or carved to look like mortar stone. Buy bagged dry concrete from a home improvement store or wet concrete delivered from a ready-mixed concrete truck. Leave the design, formwork, and pouring to the professionals. Like mortar masonry, the wall must be supported by a reinforced concrete foundation with drainage holes. It is the only type of wall that does not lean against the ground (leans back).

Sold at masonry and home improvement stores, these retaining wall blocks have a rough surface, and simple appearance, and come in a variety of colors, including gray, brown, and red. Like wood or stone walls, they are built on a crushed stone base. The mesh is sturdy and each strand is anchored to the ground.

Repair An Existing Retaining Wall.
‘Can my wall be salvaged?’ Only a structural engineer or mason can say for sure, but if yours shows any of these signs, it may be time for a new one
A wall that is leaning, as shown in the photo, is out of this world. Whether it is due to tree roots, poor drainage, or an inadequate foundation, a leaning wall will likely have to be torn down and rebuilt from scratch.
In the case of poured concrete, small scratches can be filled with hydraulic cement. In the case of a mortar wall, the damaged grout can be scraped out and re-hammered. However, if the crack is more than 1/4 inch wide and deep and 2 feet long, there may be structural damage to the wall. Consult a professional to determine if repairs can be made or if replacement is necessary.
Noticeable sagging in each course of a wood or block wall indicates that the foundation has been damaged in one location. A professional may be able to replace the foundation in the damaged area and rebuild the wall in that area only.
A thick belly in mortar masonry may be caused by water pressure behind it. Use a masonry bit to drill a 1/2-inch drainage hole to promote drainage. Swollen walls in wood or block construction are usually caused by inadequate anchorage. Careful excavation of the back of the wall can help rebuild the protrusion. Consult an expert before beginning work.
