Question 1

Is it normal to have cracks in your basement floor?

Accepted Answer

•

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.

Question 2

Can you pour concrete over an existing basement floor?

Accepted Answer

•

Yes, you can pour concrete over an existing concrete basement floor to save time and money on fully ripping out an existing concrete slab. However, it’s not a perfect solution, so consult a pro before moving forward. You must take specific measurements, and these kinds of floors don’t have the same longevity.

Question 3

Should I patch, resurface, or replace my concrete?

Accepted Answer

•

Concrete blemishes such as chipped steps or small cracks are fixable with patching. For bigger jobs, including driveway repair and cracks wider than a 1/4 of an inch, patches will only serve as a temporary fix. Resurfacing is ideal when the surface is showing more widespread wear—like if it’s pitted, rough, or has lots of cracks. Resurfacing gives your concrete a fresh, like-new appearance without needing a full replacement.

When the concrete is severely cracked, sinking, or otherwise structurally unsound, replacing it might be your best option. Replacement ensures the safety and longevity of the surface in this case.

Question 4

Why is my concrete cracking?

Accepted Answer

•

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

Question 5

What is concrete resurfacing, and is it the same as a concrete overlay?

Accepted Answer

•

Concrete resurfacing is the process of applying a new, thin layer of concrete over an existing concrete slab to enhance its appearance and durability. The terms 'concrete resurfacing' and 'concrete overlay' are often used interchangeably, though the exact meaning can vary between contractors. Generally, both refer to applying a layer of pre-blended concrete, typically between 1/4-inch and 1-inch thick. Some contractors may use 'overlay' to describe a thicker application that adds structural integrity, while 'resurfacing' might refer to a thinner, more cosmetic layer. This process is a cost-effective alternative to completely replacing the concrete, as it uses significantly less material than pouring a new 4-inch slab. Resurfacing also provides an opportunity to add new colors or stamped textures. Other names for this process include concrete restoration, concrete refinishing, and concrete rejuvenation.
