J is for Joints

A joint in a concrete substrate is created to control the shrinkage and expansion of the slab, minimising cracking.

There are two main types of joints;

• Saw cut joints – used to control initial shrinkage 
• Pre-determined construction joints – which provide long term solutions for expansion and contraction of concrete slabs.

When it comes to resin floor coatings, although they can have some elasticity, most will not be able to cope with bridging movement joints. In order to avoid cracking of concrete substrates and delamination of a subsequent resin floor coating, movement joints will need to be mirrored through the final floor finish.

On most projects, expansion joints are marked prior to a resin floor coating application. This allows for the resin floor coating to initially overlay any construction joints. Once cured, applicators will then re-cut the joints and fill the void with a suitable flexible sealant. This is done to achieve a higher quality, neat and aesthetically attractive finish.

Once joints have been mirrored through, if the area remains unfilled, it will attract dirt and contaminates. This is not only unsightly and unhygienic but it can cause the joint to shear, as concrete movement and expansion can be limited by debris.
