Building Strong Foundations Across New York City
Helping property owners with their projects, solving issues efficiently, and delivering dependable, high-quality construction service.
Injection repair for vertical, diagonal, and cold-joint cracks, with an assessment of whether the crack is stable or still moving.
Carbon fiber strapping, steel I-beam bracing, and wall anchors for basement walls pushed inward by soil pressure on sloped Bronx lots.
Pier and pit underpinning where footings sit on fill next to rock ledge and the building has settled unevenly.
Interior perimeter drains, sump pumps, and slab repair for basements dealing with perched water sitting on top of bedrock.
Repair and rebuilding of block and stone foundation walls, including stair-step crack repair through mortar joints.
Exterior membrane and drainage where access allows, and interior systems where it doesn't.
Work Experience
Foundation problems in the Bronx are usually a soil-and-rock story. A house in Riverdale may have its front footing on gneiss and its rear footing on fill, and the rear corner is the one that drops. A basement in Kingsbridge holds back a hillside, and the wall bows before it cracks. A building in Soundview sits on old marsh fill and settles evenly until a drainage failure makes it uneven. Prescribing underpinning for a lateral pressure problem wastes the owner's money and doesn't hold.
Sky Grid Group NY handles DOB filings, support-of-excavation requirements, and rock removal permitting before excavation ever starts. We are a foundation and masonry contractor, not a firm juggling a dozen unrelated trades, and Bronx homeowners, landlords, and property managers return to Sky Grid Group NY because the diagnosis holds up.
We identify whether the issue is settlement, lateral pressure, or another structural problem before recommending a solution.
Carbon fiber, steel bracing, and anchors are installed to proper specifications for dependable stabilization.
We account for rock, slopes, and difficult site conditions, with a clear scope and written estimate before work begins.
Our experts lead every project with clarity, responsibility, and a deep understanding of complex site requirements.
