Expansion joint repairs

Expansion joints, while necessary, can become a problem within floors, especially if the floor experiences heavy traffic. Maintenance Contracts are experts in expansion joint repairs and can repair them with minimal disruption.

What is an expansion joint?

Expansion joints, sometimes known as movement joints, are components that are added to flooring to help it withstand the natural changes that building materials will go through. They manage thermal expansion and contraction that is caused by temperature changes as well as accommodate movement caused by moisture. This helps to prevent cracks and structural damage to help your flooring last as long as possible.

Typically, these joints are placed regularly at the perimeter of large areas of flooring, or where different flooring materials meet. If working with concrete, as concrete expands the expansion joint should be at least a quarter of the thickness of the concrete slab. Expansion joints are often filled with flexible material to maintain structural support while accommodating movement.

In various flooring types, expansion joints are crucial for preventing damage. For example, a concrete expansion joint is essential to prevent cracks within the concrete slab. In tiled floors expansion joints prevent tiles from cracking or lifting due to movement, while in wooden floors they accommodate for natural expansion and thermal movement.

Expansion joints play an important role in preserving the appearance of flooring and ensuring that cracking and damage stemming from natural causes remains at a minimum.

Repairs

Maintenance Contracts offer an expert expansion joint repair service that gives you back your level floor surface.

Damaged expansion joints are not only a trip hazard, they also cause damage to fork lift trucks. And once you’ve got a problem, it’s only going to get worse – so the sooner you fix it, the better.

There are two main reasons that expansion joints become a problem:

  • Wear from fork lift trucks causing edges to break off a concrete slab. Trucks then jolt as they go over the joint, making the damage worse and the hole deeper.
  • One slab dropping due to subsidence, leaving the adjacent slab higher. The cracked concrete then gets further damaged by trucks.

Expansion joint damage is a common problem and it can be easily fixed before putting too much stress on the rest of your flooring.
