Expansion joint system can save your building

Earthquakes can cause serious damage to buildings. The expansion joint system uses a closure system that automatically reseals after an earthquake or flexible covers to prevent damage to floor and wall finishes. Gravity activated seismic floor coverings will also return to their normal position after the event. The expansion joint system can minimize facility damage, provide safe exits for residents, and provide seismic capacity of the structure.

Each building has a unique movement standard, so it is important to understand how to integrate movement into the size and coverage of expansion joints. Proper sizing of building expansion joints to accommodate joint cover assemblies and any accessories (such as fire barriers, insulation or steam barriers) is necessary to ensure optimal performance during and after activities.

What joint finishes will compliment your space? Working closely with your manufacturer will ensure that effective solutions integrate naturally with existing structures. Consider how daily building movements can replace cover systems. In order to avoid unwanted finishes or hazards, please select qualified installers to ensure the quality installation with the required finishes.

The expansion joint cover to bridge the gap caused by seismic reconstruction is a key element that has a positive impact on structural stability, occupant safety and architectural aesthetics. Providing reinforcement measures for new buildings and existing structures can greatly improve elasticity and long-term property value. Giving your property the ability to withstand earthquake events is a crucial step, never too late.

Use movable joints to avoid / prevent tiles from cracking and rolling up

1. Why do tiles move?

Tiles will expand when they are exposed to any moisture (water or even moisture) or heat. Tiles shrink when dried or cooled. There are also tiles that are subject to dynamic structural motion that causes them to move. Every day, ceramic tile installation will continue to experience expansion, contraction and dynamic movement cycle, which is why it is so important to design ceramic tiles with expansion / movement joints.

2. As a result of tile movement, no joints are moved

The expansion and contraction cycles can put pressure on the tile components, resulting in many different problems.

2.1 if the tiles are well bonded but lack expansion joints, the problem may be the cracking of the tiles or grout.

2.2 if there is not enough space for the tile components to unfold, the tiles will pop out in the middle of the floor or “tent” most of the time.

Internal moisture or cracks in external areas can cause moisture migration, causing additional damage to adjacent materials.

Therefore, generally speaking, when ceramic tile installation fails, the lack of moving joints is the factor leading to many types of failure.

3. How to install ceramic tile moving joint in ceramic tile installation

Therefore, in the installation of ceramic, porcelain, glass and stone tiles, the motion joint, also known as the motion adjustment joint, is very important for the success and life of the installation.

For external areas, or internal areas where tile work is exposed to direct sunlight or moisture, or above ground concrete slabs, install movable joints every 20 cm to 30 cm. For internal areas, the standard is every 50 cm to 64 cm.

In addition, all tile perimeter and transition areas should have movable joints. This includes all floor and wall applications.
