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.

    Larry, if you are going to have to taper this down to a featheredge then you would use the Top N Bond. The Top N Bond can be place from 1/2" down to a featheredge. So you will need to do 2 layers waiting 45 minutes to 1 hour between layers.

    CMH, you can patch the brick work with a mortar. You will need to removed the cracked and chipped mortar and then clean the joint prior to application. Then grout the new mortar in with a grout bag. The mortar will be determined by the age of the structure and location of the repair. Type S Mortar can be used above and below grade on most structures that are around 60 years old or newer. Type N Mortar can only be used above grade and can be used on structures around 75 years or newer. Any structure that is 90 to 100 years or even older, you would need to use a Type O or a Type K Mortar which we do not have in our product line. A chipped foundation can be repair with Top-N-Bond, depending on the severity of the repair. If the repair is questionable, you should consult a structural engineer prior to any repairs.

    Steve S, you should wait at least 7 days for a latex based paint or 28 days for anything other than latex. But be sure to follow the paint manufacturers recommendation for applications over fresh concrete because they may have a different requirement.

    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?
