Block Walls
Retaining walls, privacy walls, and decorative block construction — engineered and permitted.
McKinney's varied topography — particularly in older established neighborhoods and in newer communities graded for drainage — creates frequent need for retaining walls along property lines, between grade changes, and around raised planting beds. We build CMU (concrete masonry unit) block walls for three primary applications: retaining walls that hold soil against grade changes, privacy walls along property lines or around HVAC equipment, and decorative garden walls that define landscape zones.
Every structural retaining wall starts with proper footing design, engineered drainage behind the wall, and a permit where required by McKinney code. We handle the permit process, coordinate with inspectors, and build walls that meet both structural requirements and aesthetic expectations.

Our Process
Project Scope & Permit Evaluation
We assess the site, determine structural requirements, and identify whether permits and engineering are required.
Footing Excavation & Pour
A reinforced concrete footing is poured at the correct depth and width to support the wall height and soil load.
Block Laying Course by Course
CMU blocks are laid, leveled, and filled with grout and rebar as required by the engineered design.
Cap Installation
Decorative or standard caps are set to finish the top of the wall and protect the block cores from water.
Drainage Backfill & Grading
Proper drainage material is placed behind retaining walls, and final grading ensures water flows away from the structure.
Frequently Asked Questions
When does a retaining wall in McKinney require a permit?
Generally, retaining walls over 4 feet in height (measured from the bottom of the footing to the top of the wall) require a building permit and may need engineered plans. We handle the permit application process.
How tall can a block wall be before it needs engineering?
Most municipalities, including McKinney, require engineering for retaining walls over 4 feet. Even shorter walls may need engineering if they support surcharges like driveways, vehicles, or structures above them.
Can the wall be finished to look more decorative than standard CMU block?
Yes. Options include split-face block for a textured look, stucco or stone veneer over standard block, decorative caps, and integrated lighting. We'll help you choose a finish that fits your property.
What's a typical timeline for a block wall project?
Small garden walls can be completed in 2–3 days. Larger retaining walls requiring permits and engineering typically take 2–4 weeks from permit approval to completion, depending on size and complexity.
