The Sioux Promise
Three things we put
in writing — before a stone is set.
We learned the hard way what unsettles a homeowner most: surprise change-orders, a wrecked yard, and a contractor who vanishes the day the deposit clears. So we built a small set of promises that protect you from all three.
02
Clean site guarantee
Every jobsite gets broomed, dust-controlled and walked daily. Your driveway, your grass, your neighbor's view — all respected.
03
Licensed & warrantied
NJ Registered Home Improvement Contractor. Every structural pour and interlocking paver field carries our written workmanship warranty — up to 10 years, depending on the materials you choose.
The Long-Term Spec
Built for property protection —
not just curb appeal.
Most failing retaining walls in Central Jersey weren't built — they were stacked. We engineer ours with a buried leveling course, geo-grid reinforcement tied back into the slope, and a clean stone drainage chimney behind the block.
The result: walls that don't bulge, don't tilt, and don't blow out after the third heavy rain. We size every wall to the slope it's holding, with a setback and batter calibrated to the soil on your property.

Materials We Specify
Honest stone. Engineered for our climate.
Hover over a card to see what each material really is, where it comes from, and why we'd spec it for your project.
Segmental Block
Engineered concrete units with built-in lip — modular, repairable, and freeze-thaw rated.
Manufactured to lock together course-to-course with no mortar at the joint. Repointed or replaced individually if ever damaged — no need to tear down sections.
Natural Boulder
Quarried fieldstone for rustic, lifetime walls that look like they grew from the land.
Boulders are hand-selected for face profile and weight. Set on a leveling course of crushed stone with a 1:6 batter so gravity does most of the structural work.
Cut Stone
Squared veneer over a structural CMU core — the polished face of an engineered wall.
When the wall needs to be tall, plumb, and refined, we build a reinforced CMU core and wrap it in cut ashlar or hand-chiseled stone. The most premium look in the trade.
CMU + Veneer
When height and load demand it: a reinforced CMU core dressed in your chosen stone.
Engineered for walls retaining a finished elevation above 4 feet — rebar grid, poured cells, and a buried tie-back system. Veneer is purely cosmetic; the wall is structurally engineered.

Real homeowners.
Real structural retaining walls.
Tiered retaining wall along the back slope. They engineered the geo-grid, ran proper drainage, and the wall hasn't moved a hair through two heavy seasons.

Toms River, Ocean County
5-foot natural boulder wall on a steep grade. The wall looks like it grew out of the hillside. Every neighbor has asked who built it.
Matthew B.
Holmdel, NJ
Our last contractor's wall failed in three years. Sioux tore it out, engineered it right with tie-backs, and stamped the drawings. Worth every dollar.
