Retaining Walls Built for Strength, Drainage & Long-Term Stability
If you’re looking for an experienced retaining wall contractor in Sussex County, New Jersey, you’ve come to the right place. At Jw Construction, we design and build retaining walls that do more than look good — they are properly built to handle soil pressure, drainage, and New Jersey’s freeze-thaw conditions.
Whether your project is functional, decorative, or both, we build retaining walls that are structurally sound, low-maintenance, and built to last.
Types of Retaining Walls We Build
We install two primary types of retaining walls depending on site conditions, height, and budget:
- Landscape Block (Segmental) Retaining Walls
(Also known as dry-stack retaining walls)
These are the most common retaining walls installed today due to their durability, flexibility, and cost-effectiveness.
Benefits include:
- Interlocking concrete block systems
- Wide variety of styles, textures, and colors
- No visible mortar joints
- Excellent drainage characteristics
- Lower cost than traditional masonry walls
Most residential retaining walls in Sussex County are built using segmental landscape block systems.
- Masonry Retaining Walls
Masonry retaining walls are typically built using concrete block or stone with mortar and are best suited for specific architectural or structural needs.
They are often used when:
- A specific aesthetic is required
- The wall is integrated into steps or structures
- A finished stone or stucco surface is desired
What Is the Purpose of a Retaining Wall?
The primary function of a retaining wall is to hold back and retain soil. However, a properly designed retaining wall can also:
- Prevent erosion
- Create usable yard space
- Level sloped properties
- Support driveways or patios
- Improve drainage
- Enhance curb appeal and landscaping
Every retaining wall must be designed around soil pressure, water management, and structural load.
Landscape Block Retaining Walls & Excavation
Proper Planning Comes Before Construction
Before choosing a retaining wall system, several site-specific factors must be evaluated:
- Soil type (clay, sand, or mixed)
- Wall height and length
- What will be above the wall (slope, driveway, patio, structure)
- Drainage conditions
- Space constraints
- Local grading requirements
In some cases, excavation and tiered retaining walls provide a safer, more cost-effective solution than one tall wall.
The Two Most Common Segmental Retaining Wall Systems
-
Gravity Retaining Walls
Gravity walls rely on the weight of the block itself and the interlocking design of the system to resist soil pressure.
Best used for:
- Shorter retaining walls
- Lower earth pressure
- Decorative or landscape applications
Often, building two or more tiered gravity walls is preferable to constructing a single tall wall.
Reinforced (Geogrid) Retaining Walls
Reinforced retaining walls use geosynthetic reinforcement (geogrid) installed between block layers and extended into the soil behind the wall.
Advantages include:
- Increased structural strength
- Ability to support taller walls
- Reduced risk of movement or failure
- Better load distribution
The geogrid creates a reinforced soil mass behind the wall, making it significantly stronger and more stable than a gravity wall alone.
Drainage, Grading & Long-Term Performance
-
Drainage is one of the most critical components of any retaining wall. Without proper drainage, water pressure can cause walls to lean, crack, or fail.
Our retaining wall installations include:
- Proper base preparation
- Compacted aggregate foundations
- Drainage stone backfill
- Drain pipe placement when required
- Grading to direct water away from structures
This attention to detail ensures a maintenance-free wall that performs year after year.

FAQ
How tall can a retaining wall be?
Wall height depends on soil conditions, wall type, and whether reinforcement is used. Taller walls often require geogrid reinforcement.
Do retaining walls require permits?
Some walls do, especially taller or load-bearing walls. We can advise based on your location and project scope.
Can retaining walls be built in tiers?
Yes — tiered retaining walls are often safer, more attractive, and more cost-effective.
How long do retaining walls last?
When properly installed, landscape block retaining walls can last decades with minimal maintenance.
