Retaining wall installed by Salzman Services

Coastal Protection in Union Pier

The rolling topography of Union Pier requires serious structural expertise. Whether stabilizing a steep dune or carving out a flat courtyard, we build heavy-duty retaining walls engineered to withstand the unique pressures of sandy slopes. We prioritize global stability and proper drainage to prevent erosion from threatening your home. Our designs blend seamlessly with the wooded, cottage aesthetic while providing the structural peace of mind you need.

Global Stability and the "Burrito Drain" System


The failure of a retaining wall is almost always a drainage failure. In Union Pier, we ensure longevity by managing the water pressure behind the block. We implement a strict "Burrito Drain" protocol: a continuous column of clean stone, at least 12 inches wide, wrapped entirely in non-woven filter fabric behind the wall face. This protects the drainage zone from silt infiltration while allowing water to exit rapidly through a perforated drain tile. For stairs and transitions, we favor large, dry-laid natural stone slabs or solid block units, avoiding the cracking issues common with wet-laid masonry in our zone.


Technical Specifications:

  • Hydrostatic Relief: "Burrito Drain" (Fabric-wrapped clean stone column).

  • Adhesion: SRW Quick Set high-strength concrete adhesive.

  • Foundation: Compacted Clean Stone leveling pad (frost immune).

  • Stabilization: Biaxial Geogrid reinforcement for structural heights.

  • Drainage Exit: 4” Perforated pipe to daylight.


Execution & Finish
We bury the base course of the wall to lock it into the earth, resisting the forces of overturning and sliding. Backfilling is done in compacted lifts to prevent future settling of the upper lawn. We cap the wall using premium adhesives to ensure the coping is safe for seating. Our service commitment extends beyond the build; as your "Client for Life" partner, we are available to inspect and maintain the wall’s alignment and drainage performance for years to come.

Stabilizing Slopes in the Dunes


Union Pier’s topography is defined by rolling dunes and steep grades. A failing retaining wall here can threaten your home's foundation. We engineer our walls to combat the unique shifting nature of sand. Every wall is built on a fabric-encapsulated aggregate base. We install heavy-duty geotextile fabric under and behind the wall, separating the clean backfill from the native sand. This ensures that water drains freely without washing away the soil that supports the structure.

Accessing these slopes can be difficult, but our compact track loaders allow us to maneuver into tight backyards and side yards where larger machines can't fit. We carefully select wall materials—from natural limestone outcroppings to engineered block—that blend seamlessly with the Union Pier aesthetic. By combining heavy engineering with careful design, we turn eroding slopes into usable, flat outdoor living spaces that withstand the freeze-thaw cycle.

FAQ

How do you protect my trees during construction?

We are very careful. We can design walls that curve around root zones or use 'tree wells' to preserve the beautiful mature trees on your Union Pier lot.

Can you build a seat wall?

Yes! A low retaining wall (18-21 inches high) doubles perfectly as a seat wall around a patio or fire pit, adding functionality without extra furniture.

Do you handle the permits?

Yes. We know the Union Pier zoning codes inside and out. We ensure your wall is legal and properly setback from property lines.
