Yes. Drainage is a critical part of building a retaining wall that lasts, and F. La Rocca & Sons can incorporate drainage into the project when needed. Depending on your property’s conditions, solutions such as French drains, curtain drains, dry wells, perimeter drains, and proper backfill may be recommended to help move water away from the wall and reduce pressure behind it. Proper drainage protects both the retaining wall and the surrounding landscape for years to come.
Why Does a Retaining Wall Need Drainage?
After heavy rain, water naturally collects in the soil behind a retaining wall. Without a way for that water to escape, pressure builds against the wall. Over time, this pressure can cause cracking, bulging, leaning, or even complete failure.
What Drainage System Is Used Behind a Retaining Wall?
Most retaining walls include gravel backfill to help water move freely, along with a perforated drain pipe that carries water away from the wall. Depending on the property, additional grading or drainage improvements may also be recommended to keep water from collecting in the first place.
Can a French Drain Help Protect a Retaining Wall?
Yes. A French drain is one of several drainage solutions that can help manage groundwater around a retaining wall. Depending on the property, a contractor may also recommend curtain drains, dry wells, perimeter drains, or other drainage systems to move water away from the area and reduce pressure behind the wall.
How Does a Retaining Wall Contractor Decide Which Drainage System Is Needed?
The right drainage solution depends on your property’s slope, soil conditions, water flow, and the location of the retaining wall. A retaining wall contractor can evaluate how water moves across your property and recommend whether gravel backfill alone is sufficient or if additional drainage systems—such as French drains, curtain drains, dry wells, or perimeter drains—would provide better long-term protection.
Proper drainage doesn’t just protect your retaining wall—it helps protect your entire landscape. If you’re planning a retaining wall or experiencing drainage problems, call 914-632-4819 to discuss a solution that’s designed for your property.
