Building retaining walls in New Buffalo often means working within Critical Dune Areas or steep river bluffs. This requires more than just labor; it requires regulatory knowledge. Salzman Services understands the Part 353 permit requirements and erosion control standards necessary to build legally and safely here. We engineer heavy-duty walls that stabilize your slope against wind and water erosion, protecting your home while creating usable flat land for your enjoyment.
Dune Stabilization and the "Burrito Drain" System
Building retaining walls in New Buffalo often involves managing critical dune slopes or sandy grades. In these conditions, drainage is the single most important factor. Our "Rugged Luxury" standard mandates a "Burrito Drain" system: a continuous column of clean stone, at least 12 inches thick, fully wrapped in non-woven filter fabric behind the entire length of the wall. This fabric wrap is essential in sandy soils to prevent fine silica from clogging the drainage stone. Without it, hydrostatic pressure builds up, leading to wall failure. For grade transitions, we utilize large, dry-laid natural stone slabs or heavy modular blocks, avoiding wet-laid masonry that cracks in our freeze-thaw environment.
Technical Specifications:
Drainage Core: "Burrito Drain" (Fabric-wrapped clean stone column).
Foundation: Compacted Clean Stone leveling pad.
Adhesion: SRW Quick Set high-strength adhesive.
Reinforcement: Geogrid soil stabilization for slopes.
Discharge: 4” Perforated pipe daylighted to lower grade.
Execution & Finish
We bury the base course of the wall to lock it into the dune, resisting sliding forces. We compact the backfill in shallow lifts to ensure the ground behind the wall remains stable and does not settle. The capstones are secured with premium adhesive to provide a safe, stable finish for seating. We verify that the final grade swales water away from the wall. As your long-term partner, we stand ready to inspect and maintain the wall, ensuring it continues to protect your property and enhance your landscape for years to come.
Stabilizing Dune & Slope
The topography of New Buffalo is defined by rolling dunes and steep grades, especially near the lake. Managing these slopes is critical for protecting your property and creating usable outdoor space. We design and build structural retaining walls that hold back the earth while enhancing the beauty of your landscape. Whether you need to secure a eroding hillside in Forest Beach or terrace a backyard for a new patio, we use materials that harmonize with the coastal setting, such as weathered outcropping stone or textured blocks that mimic natural limestone.
Building walls in sand requires a specific engineering approach to prevent failure. Sand flows like a liquid when dry, which can undermine a wall from below. We combat this by wrapping our entire drainage backfill zone—a minimum of one foot of clean stone—in geotextile fabric. This prevents the fine dune sand from migrating into the stone and clogging the drainage, which is the leading cause of wall collapse in this region. We also excel at working in tight access areas, utilizing specialized compact equipment to build massive retaining structures in side yards that other contractors can't even reach.
