Do concrete expansion joints need to be sealed ?

 In Blog

Concrete flooring is probably the most simple floor you could have in your house. If not exposed to the outdoors, it will be protected from many dangers that lead to deterioration. However, your expansion joints and concrete need a little bit more care thanmay appear. In fact, your whole concrete surfaces might need extra caution if you don’t protect it by properly sealing it from the elements.

What is an expansion joint?

As concrete dries, it can shrink irregularly and put at risk your whole concrete slab of breaking apart. An expansion joint is a full-width cut that allows the concrete to expand and contract without cracking randomly. It allows the whole concrete slab to move without straining certain parts more than others, by isolating different parts of it. A good sealant will also reduce the risk of your concrete surfaces breaking while drying.

Why use a sealing compound?

The sealer will protect your brand-new concrete surfaces from various types of damage. The top 3 you may encounter if you don’t seal it are chips, scratches and stains. Also, cleaning your concrete floor will be much easier for you since it will now have a nice smooth look instead of a rough and porous one. The most important step in keeping your floors in good condition for a long time is the sealing of concrete floors.

Household chemicals can discolor and damage unsealed concrete pretty easily. Don’t forget that concrete is a porous material that absorbs liquids and while in cooler climates (such as summer with A/C and winter), the expansion of frozen liquid can literally destroy the surface of your concrete slab.
