Why Retaining Walls Are Essential in St. Louis: Local Challenges

St. Louis’ unique geography and climate create specific needs for retaining walls. From the Mississippi River bluffs to suburban backyards, here’s why they’re critical:

  • Erosion Control: St. Louis receives 41 inches of annual rainfall, often in intense spring downpours. Clay-heavy soils in areas like Creve Coeur are prone to erosion, washing away landscapes and threatening foundations. Retaining walls stabilize slopes and prevent soil loss.
  • Floodplain Risks: With 20% of St. Louis in FEMA flood zones (per 2025 data), low-lying areas like Maryland Heights face runoff issues. Walls redirect water and protect properties.
  • Aesthetic and Property Value: St. Louis homes, especially in historic neighborhoods like Soulard, benefit from terraced designs that maximize usable space and boost curb appeal by up to 15%, according to local real estate trends.
  • Soil and Terrain: The region’s loess and clay soils, combined with hilly terrain in West County, make retaining walls essential for managing uneven landscapes and preventing slides.

Poorly built or absent retaining walls can lead to costly damage—cracked foundations, flooded basements, or ruined landscaping. RWPS LLC designs walls that comply with St. Louis building codes and withstand Missouri’s weather extremes.

FAQs

What is a retaining wall?

A retaining wall is a rigid structure built to support soil laterally, allowing different ground elevations on either side. It prevents erosion and holds back soil on sloped properties, often used in landscaping, road construction, and garden design. Retaining walls can be made of concrete, timber, stone, or interlocking blocks and are essential for creating level surfaces on uneven terrain.

How do I choose the best material for a retaining wall?

Choosing the best material depends on budget, aesthetics, soil conditions, and wall height. Common options include:

  • Concrete blocks – durable and modern-looking.
  • Natural stone – attractive but more costly.
  • Treated timber – budget-friendly, but shorter lifespan.
  • Poured concrete – very strong, ideal for taller walls.

For long-term performance, also consider drainage requirements and soil movement behind the wall.

Do I need drainage behind a retaining wall?

Yes, proper drainage is crucial. Without it, water pressure can build up behind the wall (hydrostatic pressure), leading to cracking or collapse. Most retaining walls include:

  • Gravel backfill
  • Drainage pipes (weeping tiles)
  • Filter fabric

Good drainage ensures the wall remains stable for years.

How long does a retaining wall last?

The lifespan of a retaining wall depends on the material and construction quality:

  • Concrete or stone walls can last 50–100 years.
  • Timber walls typically last 15–25 years.
  • Regular maintenance and drainage can significantly extend its life.

Professional installation improves longevity and reduces future repair costs.

Do I need a permit to build a retaining wall?

In many areas, yes. If the wall is over a certain height (often 3–4 feet), or it supports a structure or vehicle load, a permit and engineering approval are likely required. Always check with your local municipality before construction to avoid fines or teardown orders.
