Architectural Joint

Expansion joints are essential in construction to allow for the natural expansion and contraction of building materials due to temperature changes, moisture variations, seismic activity, or settlement. They are intentional breaks in construction that accommodate these movements, preventing structural damage.

Expansion joints can take various forms depending on the type of construction and the materials used. In buildings, they may appear as gaps between sections of concrete, metal strips embedded in concrete, or flexible materials like rubber or silicone inserted between sections of a building. 

These joints are crucial for maintaining the structural integrity and longevity of buildings and infrastructure, as they prevent the buildup of stress that can lead to cracks, leaks, or even collapse. Properly designed and installed expansion joints are a fundamental aspect of architectural and engineering practice, ensuring that structures can withstand the forces they encounter over time.

Landscape Joints

In landscaping, materials used for expansion can be wood, rubber, bitumen, plastic, felt, silicone, polymers or even a few millimetres air gap.

In the case of wood, this material by its nature will naturally rot after a period or exposure to water and air and leave a void when it's completely perished.
