Concrete Challenges Of Converting Basements, Garages to Living Space

(ARA) - For homeowners looking to improve the value of their homes - and cope with the needs of multiple generations living under one roof - basement and garage renovations make sense. Both can enhance home value and add living space for less than one might spend on building an addition.

Basement and garage projects recoup 66.8 percent and 57.2 percent of their original costs, respectively, at the time of resale, according to Remodeling Magazine's Cost vs. Value Report. And millions of American households now consist of multiple generations living under one roof, U.S. Census Bureau statistics show. Before you dive into one of these worthwhile renovation projects, you should consider an often-overlooked logistic of working in a basement or garage - the concrete floor beneath the structure. Often, converting a basement or garage into usable living space involves adding plumbing for a bathroom or kitchenette. Usually, that means cutting into the concrete to install pipes, drains and storage tanks.

"Professional plumbers may regard digging through concrete as simply one of the hazards of their trade," says Chris Peterson, West Coast regional sales manager for SFA Saniflo, which makes above-floor plumbing products. "But cutting through concrete is simply a bad idea whose time has long gone. There are some truly sobering hazards to ponder before homeowners agree to allow anyone to cut into the concrete floor of their basement or garage."

Finally, the factor that can be the biggest issue of all for homeowners trying to keep a project on budget: cutting concrete can be very costly.

"The actual expense of cutting concrete depends on the size and complexity of the job, as well as the availability and rates of labor in your area," Peterson says. "In some parts of the country, the per-foot rate may be a few hundred dollars, and $1,000 or more in others. If the job turns out to be harder and more time-consuming than he expected, or if he has to rent additional tools, a contractor will likely pass those cost-overruns on to the homeowner."

So what's the solution if you must add a bathroom or kitchen to your basement or garage renovation?

"Above-floor plumbing is a more cost-effective, time-friendly alternative to cutting through concrete and installing traditional below-floor plumbing," Peterson points out.

Macerating - or up-flush - plumbing systems don't require installers to cut through concrete or dig. The system can be installed right on top of the existing floor. Waste and water from a toilet, tub or sink is pumped through small-diameter piping, rather than flowing down like conventional plumbing.

The up-flush system doesn't store waste. Log on to to learn more about above-floor macerating systems.
