Conventional Foundation for a Reinforced Concrete Dry Stack Retaining Wall

Retaining walls play a crucial role in preventing soil erosion and maintaining the stability of slopes. A conventional foundation is necessary to ensure the structural integrity of a reinforced concrete dry stack retaining wall. In this article, we will guide You through the step-by-step process of building such a foundation.

Introduction

Before we dive into the specifics of constructing the foundation, let's understand the importance of a strong and stable base for a retaining wall. A well-designed foundation provides the necessary support and stability to the wall, allowing it to withstand the forces exerted by the retained soil.

Setting Up the Foundation

To begin the construction process, several steps need to be followed to set up the foundation properly. These steps include placing rebar and concrete separators and tying them securely.

Placing Rebar and Concrete Separators

Firstly, you need to place number 5 rebar on top of concrete separators. The concrete separators ensure a 3-inch clearance between the ground and the concrete. It is crucial to follow the specific project Dimensions and specifications as every project may have unique requirements.

Tying the Rebar and Concrete Separators

The rebar needs to be tied securely with wire and pliers, ensuring it does not get displaced during the concrete pouring process. This is particularly important as the force of the concrete can move the rebar if not tied tightly enough. Repeat the same procedure for the Second mat, which will be identical to the first one.

Tying Foot Separators

Now, it's time to tie the foot separators made from number five rebar. These separators are used to separate the first and second mats, providing a total Height of 15 inches from the ground. Once the foot separators are in place, tie the second mat directly above the first one.

Pouring the Foundation with Concrete

With the foundation properly set up, it's time to pour the concrete. Make sure the foundation has gained sufficient strength before proceeding to build the wall over it. A monolithic wall ensures a seamless connection between the foundation and the wall, ensuring stability and strength.

Building the Monolithic Reinforced Concrete Wall with DSM Blocks

Now that we have a strong foundation in place, let's move on to building the monolithic reinforced concrete wall using DSM blocks. DSM blocks are popular for dry stack walls, where no mortar is used between the blocks. Follow these steps to ensure a robust and visually appealing wall.

Leveling the Base Course

Start by leveling out about two inches of crushed base rock. This will provide a level base for the first course of blocks. Leveling the base course is crucial, as any tilt in the base can result in a tilted wall. Use a level and a mallet to adjust the blocks both vertically and horizontally.

Placing Horizontal Reinforcement

To enhance the strength of the wall, it is important to lay out horizontal reinforcement. Add two number 4 bars that extend through the entire length of the wall. The base course blocks should be spaced evenly to allow proper reinforcement placement.

Installing Dowels

Dowels, which are number 5 rebar, need to be evenly spaced and run from the bottom to the top of the wall. These dowels provide both horizontal and vertical reinforcement. Place the dowels on top of three-inch concrete separators, ensuring proper clearance from the ground.

Adding Additional Courses to the Wall

Build the wall by adding additional courses of blocks. Pay Attention to the stacking pattern to Create gaps at regular intervals, ensuring optimal concrete flow. Attach the dowels to the blocks and overlap the rebar where necessary for proper reinforcement.

Comparing Monolithic and Pouring Methods

In some cases, it may be more feasible to pour the footing and wall separately rather than using a monolithic setup. This is especially true when dealing with complex reinforcement systems or when the foundation lies on top of a finished grade. Consider the project requirements and choose the most suitable method.

Conclusion

Building a conventional foundation for a reinforced concrete dry stack retaining wall is a meticulous process that requires careful planning and execution. By following the guidelines provided in this article, you can ensure a robust foundation and a visually appealing wall that will withstand the test of time.
