Retaining Walls

Many properties throughout Montgomery County-especially in areas like Derwood-deal with uneven terrain, sloped yards, and persistent drainage issues. These conditions don't just limit how your outdoor space can be used-they can lead to ongoing erosion, water pooling, and soil movement that gradually damages your property over time. In many cases, homeowners reach a point where landscaping alone is no longer enough. The grade needs to be controlled, and the space needs to be restructured.

That's where a properly built retaining wall becomes essential.

At Diversified Contractors, LLC, we focus on designing and constructing retaining wall systems that solve these real-world property challenges. Our approach is not about adding decorative features-it's about stabilizing land, managing water, and creating usable, functional space that holds up long-term.

When a Retaining Wall Is Necessary

Retaining walls are often installed when the natural grade of a property starts to create problems that impact both usability and structural stability. One of the most common issues we see is slope-related erosion, where rainfall gradually washes soil downhill, exposing roots, shifting surfaces, and creating uneven ground.

Drainage problems are another major factor. Water that isn't properly directed will follow the path of least resistance, often collecting near foundations, pooling in low areas, or moving across patios and lawn space. Over time, this can lead to soil saturation, instability, and damage to surrounding features.

In other cases, the issue is simply lack of usable space. Sloped yards may look manageable from a distance, but they limit how the property can actually be used. Outdoor living areas, seating zones, or even basic lawn use become difficult without creating level ground.

A retaining wall addresses all of these issues by holding back soil, controlling grade changes, and allowing for intentional layout design. Instead of working around the slope, the property is reshaped to function properly.

Types of Retaining Walls We Build

Every property presents a different set of challenges, which is why retaining walls are designed based on both the terrain and how the space will be used. Our work focuses on structural performance first, with design tailored to support that function.

Structural Retaining Walls: These are built to manage significant grade changes and hold back large amounts of soil. Structural walls are engineered to handle pressure from both soil and water, making them critical in areas where slopes are steep or where erosion has already become an issue. These walls are designed with reinforcement, proper base preparation, and integrated drainage systems to ensure long-term stability.
Tiered Retaining Walls: For properties with more extreme elevation changes, a single tall wall is not always the best solution. Tiered retaining walls break the slope into multiple levels, reducing pressure on each wall while creating flat, usable sections of land. This approach not only improves stability but also opens up the space for functional use, such as planting areas, pathways, or outdoor living zones.
Seating and Low Walls: In some layouts, lower retaining walls can be designed to double as seating or edge definition. While these walls still require proper construction, they are typically used in conjunction with larger structural elements and are not intended to handle major load-bearing conditions on their own.

Our Retaining Wall Construction Process

A retaining wall is only as strong as the way it's built. Long-term performance depends on what happens below and behind the wall-not just what is visible on the surface. At Diversified Contractors, LLC, we follow a structured construction process to ensure every wall is built for stability and durability.

Site Preparation and Excavation: The process begins with evaluating the existing grade and removing soil where necessary to establish a stable construction area. Excavation is carefully planned to account for both the wall footprint and the base material required to support it.
Base Preparation: A properly compacted base is critical to preventing settling and shifting over time. We install a foundation layer using compacted aggregate materials, ensuring the wall has a solid footing that can support weight and resist movement.
Drainage Integration: Water pressure is one of the leading causes of retaining wall failure. Without proper drainage, water builds up behind the wall, increasing pressure and eventually leading to cracking, leaning, or collapse. We install drainage systems behind the wall, including gravel backfill and drainage outlets, to allow water to move away from the structure efficiently.
Wall Installation and Reinforcement: Once the base and drainage systems are in place, the wall is constructed using segmental retaining wall systems. These blocks are designed to interlock and distribute weight evenly, creating a stable structure capable of handling soil pressure. For taller or load-bearing walls, reinforcement methods such as geogrid may be used to further strengthen the system.
Backfilling and Final Grading: After the wall is installed, the area behind it is backfilled in layers and compacted to reduce settling. The surrounding grade is then shaped to direct water away from the wall and integrate the structure into the overall layout of the property.

Materials Built for Performance

We primarily use segmental retaining wall block systems because they are designed specifically for structural applications. These materials provide consistent strength, flexibility, and long-term durability in varying weather conditions common throughout Maryland.

Unlike traditional poured concrete, segmental systems allow for slight movement without cracking, which is important in climates that experience freeze-thaw cycles. Their interlocking design also helps distribute pressure more evenly across the wall, improving overall performance.

Material selection is always based on what will perform best under the conditions of the site, ensuring the finished wall holds up over time with minimal maintenance.

Integrating Retaining Walls Into Functional Spaces

While retaining walls are built to solve structural problems, they also play a key role in how a property is used. Once the grade is controlled and level areas are created, those spaces can be incorporated into patios, walkways, or access points between different elevations.

For example, steps can be built into or alongside retaining walls to connect upper and lower sections of a yard. Flat areas created by tiered walls can be used for outdoor seating, lawn space, or future hardscape features. The goal is not to expand into unrelated services, but to ensure the retaining wall works as part of a cohesive, functional layout.

Built to Solve Problems and Last Long-Term

At Diversified Contractors, LLC, retaining walls are approached as structural systems designed to solve specific property challenges. From erosion control and drainage management to creating usable outdoor space, every wall we build is planned with long-term performance in mind.

If your property is dealing with slope-related issues, unstable soil, or limited usable space, our team can design and construct a retaining wall solution that addresses those problems directly-while ensuring the structure remains stable and effective for years to come.
