nstalling control joints can be done in a variety of ways. There have also been debates among concrete professionals about the best methods and materials used to properly fill control joints in concrete.

There are a few different types of joints that you can use on concrete floors. You already know that concrete slabs will not bend or move without breaking which is why joints may be necessary to help keep the flooring together. There are a number of joint techniques to utilize, including:

  • Isolation joints
  • Construction joints
  • Control  joints

What are Control Joints in Concrete Floors?

Control joints are used to help prevent cracks from forming on concrete flooring. They’re also used to shape concrete floors into the exact forms they need to be. Concrete surfaces don’t easily move around independently and aren’t easy to form. Control joints can be utilized to get the more durable outcomes you might be searching for going forward.

Do Control Joints in Concrete Floors Need to be Filled?

Failure to properly fill control joints may also result in water migration into the joint between the slab and the foundation wall. Moisture entering the joint causes problems such as cracking, spalling, delamination, and loss of compressive strength. These issues can lead to the failure of the slab system.

If you’re pouring concrete for your next project, put down filler before filling in any cracks or holes. Otherwise, the concrete might not stick where you’ve poured it. Control joints can be affected by moisture and dirt if they’re not properly sealed.You can also learn more about our parent company Adhesives Technology Corporation
