HUNTINGTON, NY · SERVING LONG ISLAND'S NORTH SHORE

Hold the slope.
Protect the property.

Based in Huntington, NY and built for Long Island's North Shore — hilly, glacial, and unforgiving when it rains. We engineer retaining walls that stop soil erosion, redirect stormwater, and stabilize North Shore grades, backed by site-specific load calculations and 3D terrain modeling.

THE NORTH SHORE PROBLEM

On a hill, gravity is always working against your property.

From Sands Point to Stony Brook, the terrain that gives Long Island's North Shore its character is the same terrain that quietly destroys foundations, driveways, and yards. A properly engineered retaining wall is the single best dollar-for-dollar investment a hillside property can make.

Soil erosion

Every storm strips topsoil from sloped lots — undermining lawns, gardens, and walkways.

Stormwater runoff

Uncontrolled runoff floods basements, washes out driveways, and overwhelms drainage.

Foundation pressure

Shifting soil and hydrostatic pressure crack foundations long before owners notice.

Lost usable yard

Steep grades make yards unusable. Terracing reclaims hundreds of square feet.

WHAT A PROPERLY ENGINEERED WALL DOES

Five problems. One precisely-built solution.

We don't stack stone and hope. Every wall is designed against the specific slope, soil class, and water flow of your property — then built to outlast the house behind it. We build with Cambridge and Nicolock engineered block systems, plus traditional natural stone and pressure-treated wood.

Slope Stabilization

Engineered to resist active earth pressure and prevent landslides on grades up to 30°. The structural backbone of any hillside property.

// LOAD-RATED · COUNTY-PERMITTED

Stormwater Control

Integrated French drains, weep holes, and graded backfill redirect runoff away from your foundation — not just a wall, a complete water-management system.

// DRAINAGE-INTEGRATED

Foundation Protection

Reduce hydrostatic pressure against your home. The right wall, in the right place, can add decades to a foundation's life.

// PRESSURE-CALCULATED

Erosion & Topsoil Lock

Stop losing your yard one storm at a time. Tiered walls hold soil in place permanently, so plantings and lawn investment stay where you put them.

// GEO-FABRIC BACKED

Reclaimed Usable Yard

Terracing converts unusable slopes into flat, functional living space — patios, gardens, play areas. Real estate appraisers notice.

// SQ FT GAINED · AVG +35%

Property Value

A code-engineered, professionally built retaining wall returns 100–150% at resale on North Shore homes — and removes a documented liability.

// APPRAISER-DOCUMENTED ROI

ENGINEERING-FIRST DESIGN

We measure. We model. Then we build.

Every project starts with a topographic survey and soil assessment. We model the slope in 3D, run load and drainage calculations, and produce a stamped design before a single block is laid. That's the difference between a wall that lasts 5 years and one that lasts 50.

We build with the industry's best engineered systems — Cambridge Pavingstones and Nicolock segmental wall blocks — alongside traditional natural stone and pressure-treated timber walls. The right material for the slope, the soil, and the look you want.
