Building Strong Foundations Across New York City
Helping property owners with their projects, solving issues efficiently, and delivering dependable, high-quality construction service.
Epoxy and polyurethane injection for hairline and active cracks, sealed from the inside before water and freeze-thaw widen them.
Carbon fiber straps and steel reinforcement for cracks tied to settlement, lateral soil pressure, or bowing cellar walls.
Rebuilding and repointing rubble stone and brick foundation walls in pre-war rowhouses, where mortar has washed out and the wall is shedding material into the cellar.
Interior drainage, sump systems, negative-side waterproofing, and slab repair for cellars taking on water in low-lying neighborhoods.
Sequential pit underpinning to carry footings down to competent bearing under settling rowhouses and buildings next to new excavations.
We trace intrusion to its actual entry point, cracks, cold joints, failed vault walls, and blocked drains, and stop it there.
Work Experience
Foundation work in Brooklyn is rarely just your building. A rowhouse in Cobble Hill shares a party wall and a cellar vault with the house next door. Underpinning in Bed-Stuy means you need a license agreement with your neighbor before a crew touches the shared footing. A brownstone in a designated historic district has its own approval path. And any excavation adjacent to an existing structure triggers DOB support-of-excavation requirements, special inspections, and monitoring.
Sky Grid Group NY manages filings, controlled inspections, and final sign-off in-house, so you're not chasing an expediter while your cellar is open. We are structural concrete and masonry specialists, that is the entire scope of this company, and it's why Brooklyn rowhouse owners, managing agents, and building owners keep Sky Grid Group NY on their list.
We work with rubble stone, brick, and lime-mortar foundations, knowing when a wall needs repair, repointing, or rebuilding.
Drainage, settlement, and water intrusion are assessed together to determine the right repair.
DOB filings and required inspections are managed in-house, with a written scope and itemized estimate before work begins.
Our experts lead every project with clarity, responsibility, and a deep understanding of complex site requirements.
