How tall can a retaining wall be?

Most residential retaining walls are 3 to 6 feet tall. Walls over 4 feet typically require engineering and permits. We can build taller walls with proper reinforcement and drainage, but costs increase as the wall gets higher. For very tall slopes, we may recommend terracing with multiple shorter walls instead of one tall wall.

Do I need a permit for a retaining wall?

It depends on the height and location. Walls over 4 feet usually require a permit and engineering approval. Walls near property lines or affecting drainage may also need permits regardless of height. We handle all permit applications and inspections, so you do not have to deal with town hall paperwork. We make sure everything is done by the book.

How long does it take to build a retaining wall?

A typical residential retaining wall takes 3 to 7 days from start to finish. This includes excavation, base prep, wall installation, backfill, and drainage work. Larger or more complex walls may take longer. Weather can also affect the timeline. We provide a realistic schedule upfront and keep you updated throughout the project.

Why Retaining Walls Matter

Retaining walls are more than just decorative features. They hold back soil, prevent erosion, and create usable flat spaces on sloped properties. If you have a hillside yard or uneven terrain, a retaining wall turns unusable land into a patio, garden, or driveway.

In Ashby, where heavy rain and snowmelt are common, retaining walls protect your property from water damage. A well-built wall channels water away from your foundation and prevents soil from washing onto your driveway or lawn. Without proper drainage and structural support, hillsides can shift and cause serious damage.

We build retaining walls that last. From small garden walls to large structural barriers, your experienced concrete contractor designs and installs walls that handle the pressures of soil and water. You get a stable, attractive solution that protects your investment.

Types of Retaining Walls We Build

We offer several types of retaining walls to match your needs, budget, and landscape design. Here are the most popular options.

•Concrete Block Walls: Interlocking concrete blocks stack together for a strong, long-lasting wall. Available in different colors and textures to complement your landscaping.
•Poured Concrete Walls: Solid, reinforced concrete walls built to handle heavy soil loads. Ideal for tall walls or areas with difficult soil conditions.
•Natural Stone Walls: Traditional fieldstone or cut stone walls that blend beautifully with natural landscapes. Timeless appearance with excellent durability.
•Segmental Retaining Walls: Engineered modular blocks designed for strength and flexibility. Great for curves, terraces, and complex designs.
•Concrete Masonry Walls: Custom-built masonry structures for commercial properties, large residential projects, or specialized applications.

Each type has advantages depending on your site conditions, design preferences, and budget. We help you choose the right solution and explain the pros and cons of each option.

The Key to Long-Lasting Walls

A retaining wall is only as good as its foundation and drainage system. Many failed walls were built without proper drainage, causing water pressure to push them over. Here is how we make sure your wall stands strong for decades.

Proper Base Preparation

Every wall starts with a solid base. We excavate below the frost line and create a level, compacted gravel foundation. This prevents frost heave and settling. The first course of blocks or stones is set perfectly level so the rest of the wall builds straight and true.

Drainage Systems

Water is the enemy of retaining walls. We install drainage pipes behind the wall to channel water away. Gravel backfill allows water to drain down to the pipes instead of building up pressure. Weep holes let any trapped water escape. Proper drainage is not optional, it is essential.

Reinforcement and Engineering

Walls over 4 feet tall require reinforcement. We use geogrid fabric, rebar, or deadman anchors to tie the wall back into the hillside. For large projects, we work with engineers to ensure the design meets structural requirements. For other concrete projects, explore our patio installation services.

Quality Materials

We use top-grade materials designed for retaining wall applications. Concrete blocks are rated for structural use, not just decorative landscaping. Drainage pipes are perforated and sized correctly. Every component is chosen for performance and longevity. Need a solid foundation for other projects? Check out our foundation work services.
