Concrete Slab Foundation

These foundations are made by pouring wet concrete into forms. Metal bars add strength. Usually about 6 inches thick, some slabs go up to 24.

With no basement or crawlspace, plumbing often runs through the slab. The slab is largely hidden, so problems can be hard to detect. Inspect every spring, looking to your home’s structure and surroundings for clues.

Steps to Assess Your Concrete Foundation

 

Step 1: Begin inside your home. Check for cracks in the walls, slanted floors, or windows and doors that don’t open properly. These issues could be signs of a shifting foundation.

 

Step 2: Standing or moving water close to your foundation can weaken concrete and encourage plant growth. If you notice water around your foundation, you may have a drainage problem. If it doesn’t drain after a couple of days, contact a pro.

 

Step 3: Check the visible parts of your foundation outside your home. Look for any crumbling, chipping, or cracks. While some minor cracking is normal, any cracks wider than 1/8 inch should be looked at by a professional.
