Need basement waterproofing in Olyphant? We run 18447 every week, down Lackawanna Avenue and off River Street into the old grid blocks between the river and Grassy Island Creek. Most weekday inspections get a slot inside 48 hours. You get a free on-site walk, a chalk-marked seepage map, and a written flat-rate quote before we leave.
Olyphant housing is a mix of 1890s to 1920s miner doubles and singles on cut-stone and brick foundations in the grid blocks between the Lackawanna River and the old railway, and 1950s to 1970s block-foundation homes up on the hill off Delaware Street and Grassy Island Creek. The river-side blocks sit maybe 8 to 12 feet above the Lackawanna River, which means water table during spring thaw is uncomfortably close to the basement floor. Up on the hill, the foundations are better but the yards slope hard, so surface water runoff is the bigger problem.
Olyphant has the same mine subsidence story as its neighbors but with a Lackawanna River twist. The river and Grassy Island Creek flood routinely during spring thaw and heavy summer storms, and when the river comes up, so does the basement water table. We see the corner of Lackawanna Avenue and River Street take water into basements every 3 to 4 years during a strong spring runoff. Interior perimeter drain plus a serious battery backup sump is the required setup here, not an option. Call us for a free Olyphant basement inspection and we will talk honestly about what the river does to the water table.
What to know about basement waterproofing in Olyphant
1890s stone and brick foundations in the river-side blocks between Lackawanna Avenue and the Lackawanna River leak at the cove joint during every spring thaw. The water table rises with the river. Interior perimeter drain is the fix, battery backup sump is mandatory.
The 1950s to 1970s block foundations up on Delaware Street and the hill off Grassy Island Creek fail along the mortar joints of the block when water fills the hollow cores. Core-drilled weep holes at the base of the block tied into an interior drain is the correct repair.
The old DL&W railway corridor through town created a filled low spot that still redirects groundwater. Houses right along it see a water table 3 to 4 feet below the basement floor in a wet April.
Sump pump discharge in the river-side grid must be routed carefully. During flood stage the storm sewer backs up. We route to daylight at grade on the uphill side of the house and install freeze guard tees on every discharge.
