In Houston, retaining walls aren’t just for aesthetics—they are a necessity. Because the region is famously flat and prone to heavy rains, managing soil erosion and drainage is a constant battle for homeowners.
The biggest challenge here is our expansive clay soil. When it rains, the clay swells; when it’s dry, it shrinks. This constant movement puts immense pressure on walls, which is why professional engineering is key. Most Houstonians opt for interlocking concrete blocks or natural stone because they offer the durability needed to withstand the humidity and “heaving” ground. Timber is an option, but in our damp climate, it rarely wins the fight against rot and termites.
If you’re building one, prioritize drainage pipes (weep holes). Without a way for water to escape, the hydrostatic pressure can cause even the sturdiest wall to lean or buckle.
