Common Concrete Repair Problems and Solutions

Concrete is one of the longest-lasting, most economical building materials. However, it can crack over time for a number of reasons, including settlement, overloading, poor construction and more.

When concrete cracks or imperfections do happen, DIYers and pros often look for quick, convenient and long-lasting solutions to repair them. You can eliminate project guesswork with a portfolio of easy concrete repair product solutions for your needs.

Here are a few common, small-scale repair problems and accompanying solutions:

Repair Problem #1: Brick Mortar Cracked
Product Solution: Fix deteriorated mortar joints and cracks (from 1/8" to 3/8" wide) in concrete and masonry walls (including brick or block) with a repair solution that comes in a convenient, easy-to-use caulk tube, such as SAKRETE® Concrete & Mortar Repair.

Repair Problems #2 and #3: Cracks in Concrete Driveway or Slab
Product Solution: Cracks in a driveway or slab that are ½"-wide to ¼"-deep can be quickly fixed with a polymer-based repair material. SAKRETE offers its Concrete Crack Filler, which is ready-to-use and suitable for interior or exterior concrete surfaces.

Repair Problem #4: Loose Railings
Product Solution: When concrete cracks form, adjacent railings along steps or a perimeter can become loose. Once crack repairs are made using the appropriate concrete repair material, it’s best to use an all-purpose grouting material like SAKRETE Anchor Cement to re-anchor the bolts or railings to concrete for a secure, lasting placement.

Repair Problem #5: Broken Concrete Steps
Product Solution: One of the most common concrete repair problems is broken, cracked or chipped concrete steps. Fix them easily with a repair solution like SAKRETE Fast Setting Cement Patcher, which is ideal for applications from ½" to 2" thick. SAKRETE Concrete Bonder & Fortifier is also recommended as a concrete mix additive to help increase adhesion, impact strength and abrasion resistance.

Repair Problem #6: Active Water Leak in a Basement Wall
Product Solution: An active water leak in the basement can lead to mold, mildew and other issues if not properly fixed. Stop the flow of water in concrete or masonry walls and floors with a rapid-setting solution such as SAKRETE Leak Stopper. Plus, it’s also designed to repair cracks (that are short in length) and stop underwater leaks in pools, too.

Repair Problem #7: Worn, Flaking or Pitted Concrete Slabs
Product Solution: Return worn, flaked or pitted concrete to like-new condition with an easy-to-apply resurfacer product. SAKRETE Flo-Coat® is a resurfacer for applications of ½" to a featheredge in thickness.

Repair Problem #8: Uneven Concrete Slabs
Product Solution: Level out uneven concrete slabs and restore imperfections with SAKRETE Top‘n Bond®, which is an easy-to-use, cost-effective alternative to concrete replacement ideal for applications from ½" to a featheredge.

    Jessica, Top'n Bond can be placed from 1/2" down to a featheredge. You could place 2 layers of this material to achieve the 1" needed. Wait 45 minutes to an hour between layers. Make sure that the area is clean and free of any loose dust, debris, paints, sealers, and or oil. While the surface is damp, apply the Top-N-Bond. The biggest concern is the texture that you mentioned. If the there is some kind of stamping or stain on the surface, the Top-N-Bond will not work. If it is just raw concrete then there should not be a problem. Also keep in mind that this product is not going to match the color of the existing concrete.

    Bill, You can use a couple of different products to do those repairs. However, due to the severity of the cracks, you may end up with more cracks due to movement. The Fast Setting Cement Patcher can be placed from 1/2" up to 2" in thickness. So that product could be used in the large areas. The Top-N-Bond Concrete Patcher can be placed from a featheredge up to 1/2" in thickness. This product would be used for the pitted area. Just Keep in mind that if the cracks are too great then you could see hairline cracking telegraph through the patched areas. Also the patches will not match each other or the existing concrete.

    I had a half kidney shaped patio like section put in a few years ago between my driveway and a retaining wall we had built at same time. The driveway is sloped correctly to allow rain to run off to the south of our home. The new patio section, across the side entry driveway from the house pools water every time it rains and we have to sweep it to the driveway to get it to run off. It pools up to a inch deep. Could this product be used to pour over existing textured patio section to raise it so water runs off?

    Carol, if the surface is heaved up, then you would need to have it ground down to make it flush again. If you try to ramp it with a material you could end up with a hump.

    I have a cement apron from the garage door to asphalt driveway. The large apron is in four sections. The problem is probably tree roots underneath is raising up two of the four and now is about 1 - 1 1/2 inches higher. I have had a friend fall on it it sticks up so far. How can I level the difference without water coming into the garage? Thanks so much

    Glo, that is tough because you are dealing with 2 dissimilar substrates and they are moving independently of each other. With the joint being 2" wide and clean it to the full depth, you will have to use a concrete mix. But this is not going to hold up and you will not get a good bond to the substrate. The repair will eventually crack and break away from the cavity. If the joint was smaller you could use a polyurethane caulk with pretty good success. But with it as wide as it is, you are probably going to have to constantly maintain the area and repair it when it breaks up.

    NJ, the Sakrete Sand Mix Topping and Bedding mix modified with the Sakrete Bonder & Fortifier would work well for that application. It can be place over concrete from 1/2" up to 2" in thickness.
