1 Concrete Leveling Contractors in Hampton, New Hampshire

If you need concrete leveling in Hampton, the usual culprits are dense glacial-till mantle on the inland parcels with Hollis, Charlton, Paxton, and Woodbridge till-derived sandy loams and fragipans, and frost-susceptible silt-rich till producing freeze-thaw heave. Hampton is a town in eastern Rockingham County, southeastern New Hampshire, sitting along Interstate 95, US-1, and NH-101 about 15 miles south of Portsmouth on the Atlantic seacoast. Hampton was settled in 1638 by a group of parishioners led by Oxford University graduate Reverend Stephen Bachiler, who had formerly preached at the settlement's namesake: Hampton, England. First called the "Plantation of Winnacunnet," Hampton was one of four original New Hampshire townships chartered by the General Court of Massachusetts. The town, incorporated in 1639, once included Seabrook, Kensington, Danville, Kingston, East Kingston, Sandown, North Hampton, and Hampton Falls. The first dwelling house erected on Hampton Beach was that of John Elkins in the year 1800 in North Beach section, built on a knoll called Nut Island. The coming of the railroad in 1840 changed Hampton forever; now it was possible for tourists to travel easily from the city to stay in one of the hotels in town or at the beach. The picture of the beach as a place of leisurely resort changed forever in 1897 with the advent of the trolley: the Exeter, Hampton, and Amesbury Street Railway connected the mill towns of the area with the beach and brought thousands of visitors for a single day's enjoyment. Today Hampton (population 16,214 at the 2020 census) is the busiest beach community in New Hampshire and a major Atlantic-seacoast and Boston-corridor commuter community, with Hampton Beach State Park and the historic Hampton Beach Casino Ballroom drawing significant summer-tourist traffic. Hampton sits on the rolling till-mantled bedrock terrain along the immediate Atlantic coast of the New Hampshire seacoast region. Bedrock is principally Silurian-Devonian Berwick Formation metasedimentary rocks (mica schist and quartzite) and Eliot Formation phyllite of the Merrimack Trough, with Devonian Concord-type granite plutonic intrusions of the New Hampshire Plutonic Suite locally. Above bedrock, late Wisconsinan glacial till (a stony sandy loam mantle deposited 14,000 years ago by the retreating Laurentide Ice Sheet) blankets the inland hillsides, with extensive Presumpscot Formation glaciomarine clay (deposited in the late-glacial DeGeer Sea, when isostatically-depressed land allowed marine inundation up the seacoast lowland) on the lower-elevation parcels (this is the source of the seacoast region's well-documented marine clay slab-and-foundation problems), Holocene beach-and-dune sand on the immediate Atlantic shoreline (Hampton Beach is built on a barrier-beach-and-dune complex), tidal salt-marsh organic peat in the extensive Hampton Marsh and Hampton-Seabrook Estuary, and historic fill-and-tourist-development backfill on the Hampton Beach barrier-beach commercial parcels. Local soils include Hollis and Charlton complex on the till uplands, Paxton fine sandy loam on the till uplands (with significant fragipan), Woodbridge fine sandy loam on the till uplands (poorly drained over fragipan), Buxton silt loam on the marine-clay terraces (developed on Presumpscot Formation glaciomarine clay), Scantic silt loam on the wetter marine-clay flats, Hinckley loamy sand on the outwash terraces, Windsor loamy sand on the outwash sand plains and on the inland margins of the beach-and-dune complex, Ipswich peat on the Hampton-Seabrook salt marshes, Pawcatuck mucky peat on the tidal flats, beach-and-dune sand (Hooksan loamy sand) on the active barrier-beach parcels, and Saco silt loam on the alluvial flats. Between dense glacial-till mantle on the inland parcels with Hollis, Charlton, Paxton, and Woodbridge till-derived sandy loams and fragipans, frost-susceptible silt-rich till producing freeze-thaw heave, perched-water cycling on Paxton and Woodbridge fragipan parcels driving subgrade saturation, the documented Buxton-Scantic Presumpscot-Formation glaciomarine clay shrink-swell-and-consolidation subgrade movement on the lower-elevation parcels (the seacoast region's most aggressive slab-and-foundation movement driver), the Hampton Beach barrier-beach-and-dune sand parcels with very loose-and-poorly-confined subgrade and salt-air-sulfate exposure (chloride and sulfate attack on concrete), Hampton Marsh and Hampton-Seabrook Estuary tidal salt-marsh organic-peat parcels with extreme compressibility and tidal-cycle saturation on the marsh-edge parcels, the historic 1638-onward Hampton village center National Register foundations with nearly four-century-old construction, the Hampton Beach Casino Ballroom and 1897-trolley-era boardwalk historic-tourist-corridor parcels with mill-tailings-and-fill backfill variability, and dense seacoast-Boston commuter and Hampton-Beach-tourist-development cut-and-fill on the recent I-95 corridor parcels, subgrade behavior is the primary driver of slab movement here.
