Retaining Walls with Integrated Drainage on the CT Shoreline
When drainage problems meet grade changes, a retaining wall with proper drainage behind it is often the right engineered solution. Drainage Pro of CT builds dry-stacked stone and block retaining walls under four feet in height with integrated drainage systems for properties across the CT shoreline. Every wall we build has drainage behind it, because retaining walls without drainage are retaining walls that fail.
Why Most Retaining Walls Fail
The number one cause of retaining wall failure is inadequate drainage. When water accumulates behind a retaining wall, it creates hydrostatic pressure — the weight of water pushing against the wall from the soil side. A wall designed to hold back soil now has to hold back soil and water. Most landscape-grade retaining walls aren’t built for that load, and they lean, crack, or collapse.
We build walls as drainage structures first and retaining structures second. The crushed stone backfill behind our walls provides a drainage reservoir. The perforated pipe at the base of the wall carries collected water to a discharge point. The filter fabric keeps soil from clogging the stone. The result is a wall that never has to fight water pressure because the water is managed before pressure builds.
What We Build
We install dry-stacked stone and interlocking block retaining walls under four feet in height. This includes segmental block walls for a clean, modern appearance, natural stone walls for a traditional aesthetic, and combination walls that pair functional retention with landscape integration. Every wall includes a full drainage system behind it: crushed stone backfill, perforated drain pipe at the base, filter fabric barrier, and a discharge route for collected water.
Our Scope
We build walls under four feet in height. Walls taller than four feet in Connecticut typically require engineered plans stamped by a professional engineer, and the construction techniques differ significantly. If your project calls for a wall taller than four feet, we’ll tell you upfront and recommend a contractor with that capability. We’d rather refer you to the right specialist than take on a project outside our scope.
Retaining Wall Cost
Retaining walls with integrated drainage on the CT shoreline typically cost between $3,000 and $10,000 depending on the length of the wall, height, material choice, site access, and drainage complexity. Short walls addressing a single grade change are on the lower end. Longer walls with complex drainage integration and premium materials are on the higher end. Free on-site estimates include a drainage assessment and wall design. Every retaining wall project is backed by our 5-year workmanship warranty.
Frequently Asked Questions About Retaining Walls
Do retaining walls need drainage?
Yes. A retaining wall without proper drainage will eventually fail because hydrostatic pressure from water accumulating behind the wall pushes it forward. Every retaining wall we build includes drainage provisions --- typically a perforated pipe behind the wall base with clean stone backfill and weep holes for water to escape.
How tall can a retaining wall be?
Walls over 4 feet in height typically require engineering and a building permit in Connecticut. We build walls up to 4 feet as standard construction. For taller walls, we coordinate with a structural engineer to ensure the design meets code and handles the soil and water pressure at your specific site.
What materials do you use for retaining walls?
We build with segmental block and natural stone depending on the application, aesthetics, and budget. Segmental block is the most popular for residential projects because it offers clean lines, multiple color options, and efficient installation. Natural stone provides a more rustic appearance suited to certain properties.
