Delgado’s & Sons Enterprises high-performing concrete Retaining Walls are designed to be long-lasting and meet the highest standards of strength and durability. We have been building retaining walls for the past 20 years in the USA and we will continue to provide our services.
What is a Retaining Wall?
Retaining walls also known as revetment or breast wall is designed to resist the lateral pressure of soil. They retain soil to unnatural slopes and are used to bind two soils between two different terrain elevations.
Why choose is concrete block Retaining Wall?
Concrete Retaining walls are prized for their strength and versatility; it offers much more room for customization than any other retaining wall material. They are easy to install, durable and available in a variety of colors and textures. They are used in both residential and commercial landscaping. The landscape can be engineered for hillside farming, masonry dams, roadway overpasses, and rail lines. They are used to beautify the yard with stonework while protecting it from soil erosion and rainwater. They add aesthetics to the landscape and create a usable area to grow plantations. The concrete retaining wall also protects our homes and yards from mudslides and landslides during stormy weather.
Construction of home concrete Retaining Wall
Before planning to build a concrete Retaining Wall, it is necessary to contact your local building code official and get a permit at times.
Concrete Block retaining wall construction consists of a number of steps:
Earth is excavated to create a flat-bottom trench to pour a concrete foundation for supporting the cement block wall. Generally, the foundation should be twice as wide as the wall itself.
2. Pour the Foundation
The concrete foundation is created by pouring concrete into a hollow form lining the sides of the excavation trench, but the concrete can also simply be poured into the trench. The top of the poured foundation should be perfectly leveled. The foundation is fully hardened and cured before beginning the construction of the wall.
3. Lay the First Course of Block
Mark an outline for the cement block wall onto the surface of the foundation, using a chalk line. Lay a thick layer of mortar onto the foundation inside the outline and position the first course of cement block into the mortar and join each subsequent block with mortar before joining it to the previous block.
4. Install a proper drainage system
Backfill the wall with gravel between the rear of the wall and the slope and lay perforated drainpipe on the gravel bed level with the top of the first course of blocks.
5. Add Reinforcement
After every third or fourth course, the horizontal joint should be reinforced with metal reinforcement strips laid into the mortar. To increase the lateral strength between rows of blocks vertical reinforcement is added by filling hollow cavities with concrete and driving lengths of metal rebar down into the hollows.
6. Finish the Joints
The joints between the blocks need to be the smooth end and finished.
7. Lay Cap Blocks
Finally, the tops of cement block walls are typically capped by applying a layer of mortar, embedding metal reinforcement strips and covering the wall with solid concrete cap blocks.
Factors to consider when building a Retaining Wall:
1. The Retaining wall should counteract the tendency of the retained material to move down slope due to gravity.
2. The design of the wall must resist lateral earth pressure.
3. Drainage is one of the most crucial elements of a structural Retaining Wall. Drainage prevents lateral forces from pushing the wall outward and allows the water to move safely away from the wall. If drainage of groundwater is inadequate, it will cause hydrostatic pressure on the wall.
A good Retaining Wall design should be planned after determining the unit weight, wall height, strength properties, ground water conditions of retained soil as well as lateral pressure and soil characteristics. One of the most common failures of retaining walls is the inevitable tilting, cracking and bowing of brick.
Here at Delgado’s & Sons Enterprises you can rest assured that a successful retaining wall will be designed that will meet all foreseen environmental and structural demands.
