The waterproofing is the same; the jurisdiction differs. On the Kentucky side, Sanitation District 1 (SD1) administers stormwater and sanitary rules for Boone, Kenton, and Campbell counties instead of MSDGC, and permits route through the local Northern Kentucky offices. We build to the correct rules on either side of the river.
More detail
Northern Kentucky basements have the same geology and the same water problems as the Ohio side, because the river towns and hill neighborhoods of Covington, Newport, Bellevue, Fort Thomas, Cold Spring, and the rest sit on the same clay soils, the same Ohio River valley water table, and a large stock of the same pre-1940 stone-and-block foundations. So the waterproofing itself (interior drainage, sump systems, crack injection, encapsulation, exterior membrane) is identical on both sides of the river. What differs is the regulatory administration. On the Ohio side, the Metropolitan Sewer District of Greater Cincinnati (MSDGC) sets the stormwater and sanitary rules, including the prohibition on discharging sumps into the sanitary sewer. On the Kentucky side, Sanitation District 1 (SD1) is the regional authority administering stormwater and wastewater for Boone, Kenton, and Campbell counties, and the equivalent discharge and stormwater rules come from SD1. Building permits on the Kentucky side route through the local Northern Kentucky building and code offices rather than the Ohio jurisdictions, and individual cities may add their own requirements. The practical upshot for a Northern Kentucky homeowner: you get the same systems and the same warranty, and we handle the SD1-compliant discharge design and any local permitting and locates as part of the job, just as we do MSDGC compliance on the Ohio side. A contractor unfamiliar with which authority applies on your side of the river is a small but real warning sign, because a discharge built to the wrong jurisdiction's rule (or to no rule) is the kind of detail that surfaces as a problem at resale or during a future permitted project. We work both sides of the river routinely and build each job to the rules that actually apply at your address.
