How Retaining Walls Help Control Flooding
The main purpose of retaining walls is to hold back soil, but they also play a key role in water management. Here’s how they help mitigate flooding:
1. Diverting Water Runoff
The well-constructed walls can redirect rainwater away from vulnerable areas such as foundations, driveways, and basements. It stops soil erosion and pooling by controlling the flow.
2. Preventing Soil Saturation
Too much water weakens the soil, which increases the possibility of foundation damage or landslides. These walls reinforce the soil, which keeps it stable even during heavy rainfall.
3. Improving Drainage Systems
Professional masonry contractors often integrate drainage solutions like weep holes, French drains, or gravel backfill behind walls. These features ensure water doesn’t accumulate, reducing hydrostatic pressure that could cause a structure to collapse.
4. Elevating Landscapes
Raising the ground level with a retention wall can protect homes and landscapes in flood-prone areas by acting as a barrier against rising water.
Best Retaining Wall Materials for Flood Prevention
The right material choice depends on durability, permeability, and installation expertise.
Material | Pros | Cons |
Concrete Blocks | Durable and customizable | Requires professional installation |
Poured Concrete | Seamless design | More expensive |
Brick | Aesthetic appeal, good durability | Less permeable, may require drainage additions |
Natural Stone | Visually appealing, long-lasting | Higher cost, complex installation |
Stone masonry is the best option for Metairie’s climate because of its durability and resistance to water damage.
Key Features of an Effective Flood-Resistant Retaining Wall
Simply building a wall isn’t enough; proper engineering is critical. Here’s what makes it effective against flooding:
- Proper Drainage: Without adequate drainage, water buildup can cause structural failure. Contractors should include weep holes or drainage pipes.
- Strong Foundation: A deep, reinforced footing prevents shifting during heavy rains.
- Sloped Design: Walls with a slight backward lean (batter) handle pressure better.
- Permeable Backfill: Gravel or crushed stone improves water flow.
- Professional Installation: DIY walls often collapse due to structural integrity.

How tall should a flood-resistant retaining wall be?
Height depends on property slope and water flow. A masonry contractor can assess the ideal height for maximum protection.
How long does a retaining wall last?
A professionally built one can last 30-50 years, depending on materials and maintenance.
Can I build a retaining wall myself?
DIY is possible for small walls, but professional installation is recommended for stability, drainage, and compliance with codes, especially in flood-prone areas.
How long does the installation usually take?
Installation time varies by size and complexity but typically ranges from a few days to a couple of weeks.
How important is proper grading in flood prevention?
Proper grading directs water away from your home’s foundation, working hand-in-hand with masonry structures to prevent water accumulation.
