Question 1

Do I need a permit for a retaining wall on Long Island?

Accepted Answer

Permit requirements vary by municipality across Long Island. In general, retaining walls over 4 feet in height require a building permit and may need engineering drawings. Some towns have stricter thresholds. We research the specific requirements for your town or village and handle all permitting as part of our project management, so you never have to worry about compliance.

Question 2

How long does a retaining wall last on Long Island?

Accepted Answer

A properly engineered and installed retaining wall will last 50 years or more. The key factors are a solid compacted aggregate footing, proper drainage behind the wall, correct batter or setback on each course, and quality materials rated for freeze-thaw exposure. We build every wall to exceed industry standards so your investment stands the test of time.

Question 3

What causes retaining walls to fail?

Accepted Answer

The most common cause of retaining wall failure is poor drainage. When water builds up behind a wall and has no way to escape, hydrostatic pressure pushes the wall outward, causing it to lean, crack, or collapse. Other causes include an inadequate footing, improper backfill material, lack of geogrid reinforcement on taller walls, and using materials not rated for structural loads. We address all of these factors in every wall we build.

Question 4

What is the best material for a retaining wall on Long Island?

Accepted Answer

The best material depends on the wall purpose and your aesthetic goals. Interlocking concrete block systems from Cambridge and Nicolock are the most popular choice because they are engineered for structural performance, come in many styles and colors, and are highly durable in our climate. Natural stone like fieldstone and bluestone offers a more organic, timeless look. We help you select the right material during your consultation based on your design vision and budget.

Question 5

Can you repair or rebuild an existing retaining wall?

Accepted Answer

Yes, we frequently repair and rebuild failing retaining walls across Long Island. If a wall is leaning, cracking, or has sections that have shifted, we assess the root cause and recommend either targeted repairs or a full rebuild depending on the severity. In many cases, rebuilding with proper drainage and reinforcement is the most cost-effective long-term solution.
