Poured Concrete Retaining Walls
The strongest option. A poured concrete wall with proper footing, reinforcement, and drainage is built to last decades. It handles the soil pressure from North Texas clay better than any other material. The trade-off: highest up-front cost and less visual texture (though it can be stamped or textured).
Block (CMU) Retaining Walls
Concrete masonry units (cinder blocks) are a middle ground — strong when properly reinforced and filled with rebar and grout. Segmental retaining wall blocks (the interlocking kind) are popular for shorter walls. They offer texture and color options. The trade-off: joints can allow water intrusion if drainage behind the wall isn't done right, and tall block walls need engineering.
Timber Retaining Walls
The most affordable option — treated landscape timbers or railroad ties. They look natural and are DIY-friendly. The trade-off: wood rots. Even treated timber has a finite lifespan in North Texas soil and climate (10–15 years typically). Termites are a risk. Timber walls are a short-term solution, not a long-term one.
Durability Comparison
Poured concrete: decades. Block: 20+ years when properly built. Timber: 10–15 years before rotting. In North Texas clay, which moves significantly, poured concrete's monolithic structure handles the pressure best.
Our Take
For walls that need to last — especially tall walls or walls holding back significant soil — poured concrete is the right call. For shorter, decorative walls, block can work well. We don't recommend timber for anything you want to be permanent. We assess your situation and recommend the material that fits the need and your budget.
