Exterior Excavation & Membrane in Florence
The crew excavates down to the footer, cleans and seals the exterior foundation wall with a waterproof membrane, and installs or replaces the exterior footer drain in clean gravel. Exterior waterproofing addresses water on the positive (outside) side of the wall before it reaches the basement. It is the most thorough and most disruptive option, reserved for the situations where it is genuinely the right call. Florence sits within our service area for Greater Cincinnati and Northern Kentucky, with same-week scheduling typical for routine jobs.

Exterior Excavation & Membrane in Florence: suburban mix foundations and Boone County drainage conditions
Exterior Excavation & Membrane in Florence is excavation to the footing, a membrane or coating, and a new footing drain, applied to the outside face of the foundation wall. The service is the durable option when grade, downspout routing, or hydrostatic pressure is the root cause and the lot allows machine access.
Florence mixes 1960s-1980s block-basement housing with extensive later subdivision construction on poured basements and sumps, so the city's water-entry profile spans two eras rather than one. Older block sections along the established core see joint seepage as mortar and parging age, while the newer I-71/75 corridor subdivisions generally already have a working sump and footing drain, so their calls tend toward backup power or discharge-line problems instead. Boone County's clay-heavy soil holds water longer than sandier ground, which keeps hydrostatic pressure a factor across both eras of Florence housing. Water reaching a foundation in Florence is a drainage problem before it is a foundation problem, so grade, downspout routing, and the existing footing drain are assessed before any interior work is quoted.
Boone County's newer airport-corridor subdivisions around Hebron and Florence generally have the lot room an exterior dig needs, and the clay-heavy soil found across the county is exactly the condition a footing-drain-and-membrane exterior system is built to manage, since clay holds water against a wall longer than sandier ground does.
Excavation near a property line or a right of way typically needs a permit, and utility locates are required before any dig. Permitting in Florence routes through the Boone County KY building department.
