Epoxy Floor Coatings in Fort Salonga, NY

Fort Salonga counted 9,652 residents at the 2020 census across 13.23 square miles, more than a quarter of it water, along the Long Island Sound shore between Northport and Kings Park. It is a hamlet and census-designated place in two towns at once, the Town of Huntington and the Town of Smithtown. The area was once called Fresh Pond; the current name comes from a Revolutionary War-era British fort that stood near the Huntington-Smithtown line and was attacked by colonial forces who landed at nearby Crab Meadow, and the fort site has been on the National Register of Historic Places since 1982. The most visible structure on the shore today is the Northport Power Station, located in Fort Salonga, whose first unit began operating in 1968. The hamlet shares the Northport ZIP code, 11768.

The houses are older than the power plant. Census Bureau estimates for 2020 to 2024 put the median year built in Fort Salonga at 1962; 1,054 of its roughly 3,500 housing units, 30 percent, date from the 1950s alone, and two-thirds were built before 1970. A garage slab from that era was poured decades before today's code required a vapor retarder under it, and after seventy Long Island winters it often carries a history - settlement cracks, pitting at the apron, old patches, oil worked deep into the wheel paths - that has to be dealt with before any coating goes down. On a floor that age, crack and joint repair belongs in the quote from the start rather than as a surprise on install day. For work beyond a coating, the permit office depends on which side of the town line the property sits: on the Huntington side it is the Building & Housing Division of the Engineering Services Department, which reviews plans and issues building permits, and on the Smithtown side it is the Town of Smithtown Building Department.

Harbor Hill Moraine Ground Under Seventy-Year-Old Slabs

Fort Salonga's high ground belongs to the Harbor Hill moraine. USGS mapping of the Huntington-Smithtown area describes it as an irregular, discontinuous ridge that trends east-northeast across the entire area, with summits generally reaching 250 to 300 feet, and USGS describes the same line of hills running east along the north shore to form the North Fork. Moraine is not the clean, sorted sand of the outwash plain to the south. It is the mix of sand, gravel, silt and stones the ice left where it stalled, and it drains unevenly: water moves quickly through the sandy layers, stalls on the silty ones, then travels sideways until it finds a way out, often at a foundation wall or a slab edge. On a hillside lot that makes the uphill side of a garage slab the wet side, and on any older slab it makes a single moisture reading unreliable. Readings go in several spots, including the corner nearest the high ground, and the primer is specified to the worst reading, not the average.

The slab itself is usually the bigger project. A 1950s or early 1960s garage floor has seen decades of road salt, oil drips and freeze-thaw, and the damage concentrates where tires carry brine in and park: the apron, the first few feet of the bay and the wheel paths. The Islip station averages 101 days a year at or below freezing, so a salted slab near the door goes through that cycle again and again every winter. Pitting and scaling are ground back to sound concrete and filled with a resin mortar that cures hard enough to grind flush. Oil is a separate problem, because resin will not bond to oil-saturated concrete; stained areas are degreased and ground, and a deeply soaked patch may need to be cut out and replaced. Where the surface feels weak or dusty, a pull-off test under ASTM D7234 settles whether the concrete is strong enough to hold a coating at all. If the test plug comes away with concrete attached, the slab is the weak link, and a repair topping comes before any resin.
