Did they cut any joints in it? If not, then the concrete jointed itself by cracking.
Actually, I don't think I've ever seen a basement slab that wasn't cracked. The cracks are drying shrinkage cracks, and they usually happen the day after the pour. That's what cut joints are for...to control where the slab cracks.
Usually, an indoor crack is not a "working crack" affected by changes in temperature, freezing, etc., so they pose no problems other than aesthetics. This is especially true if you are carpeting over it anyway. No worries.

Concrete sealer peeling on garage floor

D

ductbert on Jul 07, 2008

When I became a homeowner, I painted the floor of our garage with an exterior silicone acrylic concrete sealer from Sherwin Williams. Three years later, it's peeling and flecking up off the floor. In one place where water tends to pool, it's completely gone. I attribute the problem to a lack of experience and improper surface preparation. I also wonder if I really used the best product for the job. That's the sucky thing about being a new homeowner--you don't usually get an opportunity to practice something like this first and learn from your mistakes before trying it out on something you own. I'm looking for ways to remove the sealer safely and preferably without using a pressure washer. I've recently installed pegboard on all of my garage walls and don't want to get it wet. I've read a few ideas online such as soaking a white sheet in xylene and peeling it away when it dries. Could I use a machine (scarifier?) to grind it away instead of using chemical strippers? Also, I'd like to know what products you might recommend to re-seal the floor once I strip it and properly prepare the surface. Thanks!Read More

Mobile home leveling

S

steve-1 on Jul 05, 2008

I decided to take on the job of leveling my double wide mobile home because I have several cracks in the ceiling and a couple of doors that won't close properly. I used a water level under the house and found that at the location of several of the piers (cinder blocks), the I beams are 1.5 to 1.75 inches lower than the center of the house. The home has a foundation which consists of concrete that runs perpendicular to the I beams which the piers are sitting on. The problem is that when I began to jack up the low spots and insert shims, I found that there were metal supports which were welded to the I beams and anchored into the concrete next to several of the piers. This prevents me from lifting the piers enough to level the house properly. There are also anchor straps at the end of each row of piers that need losening before I lift the house. Can anyone offer me advise on this? Do I need to lower the rest of the house to match these low spots?Read More
