Whether you’re dealing with a collapsing wall or planning a new landscape design, working with experienced professionals ensures your retaining wall stands the test of time.
What is a Retaining Wall?
A retaining wall is a rigid structure designed to hold back soil and prevent erosion or landslides. These walls are common in residential, commercial, and municipal properties, especially in areas with elevation changes or sloped yards. In urban environments like Queens and The Bronx, they’re essential for maximizing usable space and supporting infrastructure.
Why Retaining Walls Matter in NYC’s Urban Landscape
In densely populated areas like Brooklyn and Queens, proper land management is vital. A poorly constructed or neglected retaining wall can cause:
- Soil erosion that damages landscaping and hardscaping
- Water pooling near foundations, leading to basement flooding
- Structural instability that may pose a safety risk
- Aesthetic issues that reduce property value
That’s why hiring professional retaining wall contractors like Zavza Seal is not just a smart move—it’s essential.
Types of Retaining Walls We Install
As specialists in building and repairing retaining walls, we offer a wide range of wall types tailored to your property’s needs:
1. Gravity Retaining Walls
These rely on their weight to hold back soil and are commonly built using stone, concrete blocks, or pavers.
2. Cantilever Retaining Walls
Reinforced with steel bars and designed in an L or T shape, these are suitable for taller wall applications.
3. Sheet Piling Retaining Walls
Ideal for tight spaces, especially in urban Brooklyn and Queens properties, using metal, wood, or vinyl planks driven into the soil.
4. Anchored Retaining Walls
Used in complex projects where additional reinforcement is necessary, such as steep slopes or water-adjacent landscapes.
5. Segmental Retaining Walls
Flexible, modular systems that are perfect for decorative landscaping in Long Island yards.

The Importance of Drainage in Retaining Wall Construction
Improper drainage is the leading cause of retaining wall failure. Without a system to divert water, hydrostatic pressure builds up behind the wall, leading to:
- Cracking
- Bulging
- Tilting
- Collapse
At Zavza Seal, every retaining wall project includes a comprehensive drainage plan—such as weep holes, gravel backfill, and French drains—ensuring durability and long-term safety.
