Joint Sealing & Caulking for Concrete in Western Michigan


Joint sealants are soft materials that protect your concrete slabs by preventing water, ice and dirt from getting into the joints and subgrade of your concrete. Kent’s sealants are designed to accommodate the slabs and to protect them over the long run.

What Is Concrete Joint Sealing?

Many homeowners are familiar with the term “caulking.” It is possible to use the terms caulking and joint sealing interchangeably, but in the professional realm, you’ll hear “concrete joint sealing” more frequently.

Why Should I Seal My Concrete Joints?

There are two important reasons to seal your concrete joints: prevention and repair.

Concrete sealants prevent water from penetrating the subgrade below your concrete by sealing cracks and joints. Many sunken concrete issues are caused by water erosion below the concrete. After we raise your concrete back to level, we can add another treatment to seal the joints, thus preventing water intrusion, erosion and damage from the freeze-thaw cycle.

In other words, we raise the concrete to correct the situation and then address the cause by sealing the concrete joints. It’s also critically important to address drainage issues surrounding your concrete. Redirect downspouts away from your home’s foundation and concrete to control the flow of water on your property.

Concrete joint sealants are also used to repair cracked concrete. Flexible sealants are designed to seal the joint and move with the concrete as it expands and contracts in various temperatures. Polyurethane materials are the most commonly used.

Rigid sealants, or menders, are designed to restore some structural integrity back into the section of broken concrete by bonding the crack back together. A Kent Home Services project manager will inspect your concrete and provide a recommendation on the best type of joint sealant for your property.

How Does The Concrete Joint Sealing Process work?

The most common process for concrete joint sealing starts with a cleaning process that clears the joint of debris. Next, a backer rod or sand is used to fill the joint to create a ¼” to 3/8″ joint depth. Kent Home Services then applies a self-leveling concrete joint sealant which is gray in color.

While many homeowners have attempted a form of caulking on a do-it-yourself basis, only a professional like Kent Home Services can provide the commercial-grade products and application process provide a total solution for protecting your concrete.
