Expansion & Construction Joints

Precision Expansion & Movement Joint Treatment

Expansion joints are one of the important areas in Civil engineering structures, where contraction and expansion take place. Joints are provided to accommodate the expansion of adjacent building parts and relieve compressive stresses that may otherwise develop. The most common types of sealants are polyurethane and Polysulphide. While both will do the job of Expansion joints filling.

At Applychem, our movement joint treatment systems combine proper joint preparation, high-density polyethylene backer rods, and heavy-duty Polyurethane and Polysulphide sealants to provide long-lasting flexibility, thermal expansion control, and absolute water tightness across structural slabs, bridge decks, and concrete walls.

• Relieves thermal expansion, contraction, and seismic structural movement stresses
• High-performance Polyurethane & Polysulphide joint sealants with high movement capability
• Prevents water ingress, chemical penetration, and debris accumulation in structural gaps
• Complete system design including backer rod positioning, joint priming, and neat tooling finish
