At RJT Construction, we specialize in designing and building high-quality concrete block retaining walls that enhance your property’s functionality and aesthetic appeal. In this guide, we will cover everything you need to know about building a retaining wall, including the benefits, steps involved, and why concrete block walls are the best choice for homeowners in Houston.
A retaining wall is a structure built to prevent soil erosion, manage slopes, and create level ground for landscaping and other purposes. It can be a crucial part of your property’s drainage system, helping to prevent water damage and erosion down to ground level. Concrete block retaining walls are a popular choice for homeowners due to their durability, ease of construction, and versatility. At RJT Construction, we take pride in constructing walls that not only serve a functional purpose but also improve your outdoor space’s aesthetic appeal.
Understanding the Basics of a Concrete Block Retaining Wall
The Purpose and Benefits of Building a Retaining Wall in Houston, TX
In Houston, where the climate includes heavy rainfall and frequent flooding, retaining walls are essential for controlling water runoff and preventing soil erosion. A well-built retaining wall can help manage slopes, turning unusable or unstable land into a usable outdoor space.
Whether you’re looking to level the ground for a garden, build a driveway, or prevent soil from washing away during storms, a retaining wall serves multiple purposes. Concrete block retaining walls are particularly effective in Houston due to their strength and resilience to the region’s moisture-rich climate and shifting soil types.
Key Features of a Concrete Block Retaining Wall
Concrete blocks offer excellent durability and strength, ensuring your retaining wall will stand the test of time. Unlike other materials such as wood or timber, concrete blocks are resistant to weathering, rot, and pests, making them a long-term solution for your property.
Concrete block walls are also highly versatile, offering various shapes, sizes, and colors to suit your aesthetic preferences. Compared to other materials like stone or timber, concrete blocks are easier to install and often more cost-effective, while still providing the same level of stability and beauty.
Step-by-Step Guide to Building a Concrete Block Retaining Wall
Building a concrete block retaining wall involves careful planning and execution to ensure long-lasting stability and functionality. At RJT Construction, we follow a thorough process to make sure your wall is properly constructed with a strong footing, including inserting rebar, to withstand the elements and provide reliable performance. Here’s a step-by-step guide to building a concrete block retaining wall: As the last step, fill the cores with mortar.
Planning and Preparation
Before starting any retaining wall project, the first step is planning and preparation. Start by determining the exact location of your wall and its size, ensuring that it fits well within your landscape design. It’s crucial to check local building codes and obtain necessary permits, especially for taller walls or if the wall will impact drainage systems.
Tools and Materials Needed
For the successful construction of a concrete block retaining wall using retaining wall blocks, you’ll need a few essential tools and materials. These include:
- Tools: Shovel, level, tape measure, rubber mallet, string line, tamper, and a hose.
- Materials: Concrete blocks (your choice of size and finish), gravel for drainage, landscape fabric, drainage pipes, and possibly mortar for added bonding strength.
At RJT Construction, we ensure that all tools and materials are of the highest quality, providing your retaining wall with maximum durability and a finished appearance that complements your property.
Excavation and Base Preparation
The next step is excavation. Begin by digging a trench for the base foundation of your wall. The trench should be wide enough to accommodate the first layer of blocks, usually about 6 inches wider than the blocks themselves. Make sure the trench is deep enough to create a stable foundation—typically 6 to 12 inches of paver base, depending on the wall’s height and frost considerations.
Once the trench is dug, level and compact the soil to create a solid foundation. Adding a layer of gravel, usually around two or three inches of gravel, at the bottom of the trench helps with drainage, ensuring water can flow freely behind the wall, preventing pressure from building up.
Laying the First Course of Blocks
Setting the first row of blocks is the most critical step. The first course must be perfectly level, so I use a torpedo level to ensure the entire wall remains stable. Use a level to check that each block is aligned horizontally and vertically.
RJT Construction ensures the first block in the first row is precisely placed to create a solid foundation for the second row of the wall. Once the first row is set, fill the base with gravel to allow for proper drainage and prevent water accumulation. This is key to ensuring the longevity of your retaining wall.
Stacking Additional Courses and Adding Drainage
After the first row is in place, you’ll stack the subsequent courses of concrete blocks to create a sturdy wall that complements your patio. Each row should be staggered to interlock the blocks and provide added stability and reinforcement. Use a rubber mallet to gently tap the blocks into place and maintain alignment.
For taller walls, RJT Construction recommends adding a drainage pipe behind the wall to prevent water buildup, which could weaken the structure over time. Once the wall is built, backfill the trench to ensure proper support. The drainage pipe should be installed at the base of the wall, leading to an outlet where the water can safely drain away from the wall and your property.
At RJT Construction, we ensure that every step of the retaining wall construction process is done with care, precision, and expertise.

Common Mistakes to Avoid When Building a Concrete Block Retaining Wall
Building a concrete block retaining wall requires careful attention to detail to ensure its stability and longevity. Here are some common mistakes to avoid:
- Improper Base Preparation: Not preparing the base correctly can lead to instability and uneven settling of the wall. It’s crucial to excavate and compact the soil properly and lay a solid gravel foundation. At RJT Construction, we ensure the base is properly prepared for maximum durability.
- Overlooking Drainage: Failure to include proper drainage behind the wall can cause water to build up, leading to pressure and cracks in the wall. Always ensure that drainage pipes are installed to direct water away from the wall.
- Misplacing the First Course: The first course of blocks is critical for the entire wall’s alignment. Misplacing or misleveling the first row can lead to a misaligned wall, which can compromise the structure. At RJT Construction, we ensure that the first row is placed with precision to guarantee a level foundation for the rest of the wall.
- Neglecting Local Building Regulations: Every location has different building codes and regulations. Failing to check these before beginning your project can lead to costly mistakes or even the need for rebuilding. RJT Construction ensures all our projects meet local building codes, saving you from unnecessary hassle.
