"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."

"I kind of questioned the cost after they did the job. What they actually did here looks pretty good. I just had surgery that time so I was in bed when they came out. They did it under 40 hours and did good work but they handed me another bill that was triple the price. The labor was okay but within that labor, they planted things for me. I had asked them to make it easy to maintain but they never discussed anything with me. I’m sure they upped the cost for the plants quite a bit. I don’t even know what plants they are. They did put in some bricks and they did a good job on that. I told them that I wanted some grooves leveled out in my yard and I realized afterwards that there were still some tracks in the yard. It was covered by grass but I pointed out where they were."

Basement Waterproofing questions, answered by experts

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
