Sewage Backup Cleanup in Oakridge Manor, Roseville, MI

What do we know about Oakridge Manor?

Listings describe Oakridge Manor as a condominium community in Roseville, reached from 13 Mile Road east of Utica Road. The units we found are dated to roughly 1988 and 1989, are described as slab-on-grade, which means a concrete slab foundation with no basement, and come with a homeowners association. We did not find building plans, drain layouts or pipe records, and we make no claims about them.

The slab detail is the useful one. Most advice about sewage in Roseville assumes a basement, because many of the city's older houses have them. A slab-built home behaves differently. There is no lower level where a backup can settle, so sewage that comes up through a fixture spreads across the living floor. That is a smaller volume in a more valuable place.

If sewage is on the floor now, stop using water and call. The emergency page lists the first-hour steps, and the raw sewage page covers what to do and what to avoid on hard surfaces.

Where does sewage show up in a slab-on-grade home?

Without a floor drain in a basement, a backup finds the lowest fixture. In a one-level home, that is usually the tub or shower, a floor-level toilet or a laundry standpipe, whichever sits lowest or is easiest to overflow. Sewage may come up through a shower drain and spread across the bathroom floor and into the adjoining hallway before it is noticed.

That has two effects. The first is that the contamination reaches finished floors, such as vinyl, laminate or carpet in the living area, instead of a concrete basement. The second is that the home's drain lines run beneath or within the slab, so a blockage or failure can be harder to reach, and some repairs involve opening the floor.

What happens to the flooring?

Floors are where most of the loss happens in a slab home. Whether a floor can be saved depends on what it is made of and what is under it, and the flooring removal page goes through each type. A few points apply here in particular.

A concrete slab dries slowly. Ask for moisture readings before new flooring is installed over it, since flooring laid over a damp slab can fail and grow mold. The drying page explains how readings are taken.

What happens to the wall bottoms and the drywall?

Sewage that spreads across a slab floor meets the base of every wall in its path. Drywall wicks liquid upward, and in a slab home the bottom plate sits directly on concrete, so moisture can linger there. A provider usually removes the baseboards and may cut the bottom of the drywall to inspect and dry the cavity. The drywall removal page explains how high the cut goes and why.

Because there is no basement to put equipment in, drying gear sits in the living space, and the unit will be noisy for a few days. Ask the provider how long to expect, and keep the thermostat as they recommend.

Why does the slab make odor harder or easier?

A slab is a mass of porous concrete, and it can hold smell when it has been wet with sewage. On the other hand, a slab can be cleaned, disinfected and dried more directly than a wood subfloor. If the smell lingers after the flooring has been replaced, the cause is usually something that stayed wet, such as the slab itself, the wall bottoms or the carpet tack strip. A provider can check readings, and the drying page explains what they mean.

Who is responsible for the plumbing in a slab condo?

The governing documents of the association decide this, and it can vary by what failed. Branch lines inside a unit are usually the owner's. Lines shared among units, and the connection to the main, are more likely the association's. Slab homes add a wrinkle: drain lines under the slab may serve more than one unit, and a failure under the concrete can take time to locate.

Notify management in writing the day it happens. Ask who owns the line, who will inspect it and whether a camera inspection is planned. If the problem was inside your unit, a plumber can diagnose the fixture and the branch line.

What can you do while you wait for help?

• Stop using every fixture in the unit until the source is understood.
• Keep people and pets off the wet floor, especially in socks or bare feet.
• Photograph the floor, the walls and the fixture the water came from.
• Move dry belongings out of the wet area only if you can do it without walking through the water.
• Note the time, and keep receipts for anything you spend.

If you rent, tell the owner and the manager the same day. Standard owner policies often exclude sewer backup without an endorsement, so ask what applies.

Who do you call?

Call (586) 352-8402. Tell the dispatcher that you are in a slab-built condo with no basement, which fixture the water came from and how far it has spread. Roseville Sewage Pros is a referral line, so the provider that arrives sets the scope and the price.
