iChem – Your trusted partner in advanced construction solutions and reliable expansion joint systems.

Expansion joints and concrete joints are critical elements for maintaining structural stability and durability, particularly in mixed-use developments like One Ninety.

Key benefits of expansion joints include:

• Protecting concrete from cracking due to thermal movement and shrinkage

• Enhancing durability in residential, commercial, and industrial buildings

• Reducing the impact of daily vibrations and seismic activities

• Providing seismic protection systems for buildings and seismic joints

Properly installed expansion joints ensure a safe environment and extend the lifespan of buildings, especially in large-scale, multi-purpose developments.

iChem provided comprehensive solutions to enhance structural stability and concrete joint performance through advanced concrete additives, including accelerators, retarders, fibers, and air-entraining agents, ensuring:

• Crack resistance

• Increased operational durability

• Improved performance and sustainability

Additionally, iChem implemented modern expansion joint systems to distribute structural loads evenly and ensure building safety under all environmental and seismic conditions.
