"I needed a garden path from my house to my art studio, and I wanted it to match the concrete path already going from my house to the garage. Not a big job, but American Concrete Construction was willing to take it on. Their main guy, Sinisia Moli, came right out one day to evaluate the job, then returned the next day to survey, dig out the path, frame it, and put in rebar. Cement was poured the following day. And now I have my garden path. Which, incidentally, matches the other, much older path perfectly. ... Sinisia Moli of American Concrete Construction is a man of experience, good aesthetics, and common sense. He is also friendly, upbeat, and generally a pleasure to have around. Best of all, unlike so many of his colleagues who work in various construction trades, Moli talks to women. He doesn’t insist on talking to your husband. ... I am definitely keeping American Concrete Construction in mind for future projects."

Basement Waterproofing FAQs, answered by experts

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.
