Floor Movement Control Joints

Buildings are designed to allow movement in response to various forces including thermal expansion and contraction long term shrinkage of structures as well as seismic activity in some cases.

Floor movement control joints.

Covers are used as expansion joint gap covers for areas that experience movement within structures for example in construction joints in concrete slabs. Floor expansion joint covers for both thermal and seismic applications our floor to floor and floor to wall floor expansion joint systems allow 6 way movement or 4 way movement whilst the surface fixed products generally cover 2 directional movement. The intent of the guideline regarding sun exposure is to recognize that areas that get warm or wet may experience greater amounts of differential expansion.

Control joints are planned cracks which allow for movements caused by temperature changes and drying shrinkage.

The movement joints expansion joints and control joint profiles of our schlüter dilex series offer maintenance free and functional solutions for all relevant movement joints in tile coverings. Why are movement joints needed.

In other words if the concrete does crack you want to have an active role in deciding where it will crack and that it will crack in a straight line instead of randomly. Not the entire floor if elsewhere the floor is an even temperature.
