Building Strong Foundations Across New York City
Helping property owners with their projects, solving issues efficiently, and delivering dependable, high-quality construction service.
Perimeter drainage, sump systems with battery backup, cove-joint sealing, and slab treatment for basements dealing with rising groundwater.
Wall coating and membrane systems for poured concrete, block, and brick foundations, including the CMU walls common in Queens homes built between the 1920s and 1950s.
Excavate to the footing, prepare the wall, install membrane and drainage board, and set a footing drain tied to daylight or a sump. Most Queens lots allow it.
For attached homes and properties where excavation isn't practical, we manage water from the inside with drainage channels and negative-side coatings.
Repointing, parging, and repellent treatment for brick and block, plus stucco repair on the many Queens homes where water enters above grade.
Backwater valves, elevated equipment, and discharge routing for properties in flood-prone south Queens.
Work Experience
Waterproofing in Queens is a borough-of-many-conditions job. A basement in Howard Beach floods on a full moon tide, not because a wall failed. A house in Bayside sits in clay that holds water against the foundation for three days after every storm. A block foundation in Woodhaven wicks moisture through the CMU cores because nobody parged it in 1938.
Sky Grid Group NY inspects the full picture, grading, drainage, tide and flood exposure, wall condition, before writing a scope, and files any permits the work requires. That focus is why Queens homeowners, managing agents, and commercial owners keep referring us.
Where the yard allows it, we stop water at the foundation wall instead of managing it after it enters.
We account for tidal groundwater in south Queens and clay pressure in the northeast when selecting the right system.
