Closed-cell polyethylene rods are highly recommended for Saudi Arabia due to their moisture resistance and thermal stability. They prevent sealant adhesion failure in humid coastal cities like Jeddah and Dammam, while maintaining structural integrity during intense summer heat. Always verify cell structure specifications before procurement.
Select a backer rod diameter 20 to 30 percent larger than the joint width to ensure proper compression. This 25 to 33 percent compression ratio creates an optimal seal, prevents sealant tearing, and accommodates thermal movement. Consult the joint depth-to-width ratio for accurate sizing.
Yes, our expansion joint seal rods meet strict SASO and local municipality construction standards for durability and safety. They are rigorously tested for chemical resistance and load-bearing capacity, making them fully compliant for government projects, commercial developments, and residential buildings across Saudi Arabia.
High-density closed-cell polyethylene foam is specifically engineered to resist UV degradation and maintain elasticity under extreme Saudi summer temperatures. Unlike standard materials, it prevents premature cracking or shrinkage, ensuring long-term joint performance and reliable sealant adhesion throughout the structure’s lifespan.
