Joint Seals / Sealants
Protect joints from incompressible materials and moisture from infiltrating the joints.
Reduction in Joint Spalling, Faulting, Erosion of the Base, Slab Growth and Protects Dowell Bars.
“Results confirmed that if joint seals areproperly installed, they can be very effective in preventing moisture infiltration and thusperformance issues related to erosion damage. Unsealed joints had significantly higherflow rates compared to joints with varying degrees of damaged sealants.”
