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.

    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.

    Joey, that would depend on which product that you are talking about. If it is one of our polymer modified products then the answer would be no. Polymer modified product will not take acid stains very well.

    Fred, we do not have a shower floor material that can be placed from 1/8" to 1". We typically recommend Sand Mix for shower pan applications. However, you would have to make you pan thicker. Follow the TCNA (Tile Counselors of North America) guidelines for shower pan installations over a concrete substrate.
