Exterior Excavation & Membrane in Mariemont, OH

Exterior Excavation & Membrane in Mariemont 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.

Mariemont's 1920s planned-village housing sits on concrete basement floors and walls that have cured and cracked over the better part of a century, and the historic district's restrictions on exterior alteration push most repair work to the interior of the foundation rather than an exterior dig. Brick and stucco exteriors do not tell you much about the wall behind them, since the original poured concrete was mixed and cured to a lower standard than modern concrete and is more porous as a result. An interior drainage retrofit here typically pairs with crack injection at the age-related cracking already present in the original pour, rather than treating the wall as sound. Water reaching a foundation in Mariemont 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.

Exterior excavation access in Hamilton County depends on which half of the metro a lot sits in: the dense pre-war urban core and hillside neighborhoods like Mt. Lookout constrain machine access with narrow lots, party walls, and cut-and-fill grading, while flatter suburban lots in the county's outer ring generally give a crew the room a full footing excavation needs. Utility locates and a permit for work near a property line apply across the county either way.

Excavation near a property line or a right of way typically needs a permit, and utility locates are required before any dig. Permitting in Mariemont routes through Hamilton County Building Department (or the local municipality where applicable).
