Municipal and Contractors Sealing Products

MCSP is a Cincinnati trenchless rehabilitation contractor founded in 2000 by Bob O’Connor, and now led by CEO Drew O’Connor. The firm began as a distributor of sealing products and resins to contractors and moved into self-performing the work. Its crews handle manhole rehabilitation, culvert restoration, large-diameter pipe rehabilitation, geopolymer and cementitious spray lining, protective coatings, chemical grout injection and structural repair for municipalities, state and federal agencies and commercial owners across Ohio, Kentucky, Indiana, West Virginia and Pennsylvania. MCSP is ODOT approved, KYDOT approved and NASSCO certified, credentials that gate most public culvert and collection-system work in its region. Houston-based Vortex Companies announced its acquisition of MCSP in September 2026.

For anything 24 inches in diameter and larger, MCSP names five restoration methods and they are not interchangeable. Cast-in-place lining sprays a high-strength cementitious coating carrying a proprietary additive blend to make the wall impermeable. Spin casting inserts a controlled spin caster into the barrel and withdraws it at a calculated speed, depositing thin layers of high-strength grout or mortar that key tightly to the original substrate. Sliplining inserts a new pipe inside the host where access and cross-section allow. Geopolymer and cementitious lining is the route offered where bacterial and chemical attack rather than load is the governing problem. Shotcreting projects a high volume of concrete mix pneumatically through a hose at velocity, which suits irregular and heavily deteriorated profiles.

The host structure list is the part worth reading before a pre-bid walk: corrugated metal pipe, reinforced concrete pipe, precast arched and box culverts, and brick, stone and tile construction. The failure modes described are collapsed or deteriorated barrels, sinkholes produced by sub-surface erosion around a leaking structure, infiltration and exfiltration, and corrosion of the invert and crown. Coatings are sourced from named suppliers rather than a single in-house line. Raven Lining Systems, Standard Cement Materials and Sherwin-Williams appear on the large-diameter restoration page, and epoxy and urethane systems are offered where bacterial and chemical exposure rules out a cementitious lining on its own. That mix of cementitious, geopolymer, epoxy and urethane is what lets one crew answer a structural problem and a corrosion problem in the same shaft.

For a public owner the approval paperwork is often the gate, and MCSP lists ODOT approved and KYDOT approved status, NASSCO certification, a Columbus pre-approved listing, and Certified SBE small business enterprise status. Field staff are trained to OSHA standards. The buyer set the company describes is state departments of transportation, State of Ohio divisions, central Ohio municipalities and Kentucky municipal contractors, worked across Ohio, Kentucky, Indiana, West Virginia and Pennsylvania from the Cincinnati base on 513-482-3300. Alongside the pipe and culvert work the solutions list also covers septic tank repair and downspout redirection, which points at the smaller private and commercial jobs that sit beside the highway and sewer contracts, and an engineered solutions category for structures that do not fit a standard method.
