Movement: ± 50% of Joint Width Joint Width: 25mm-600mm The 1100 and 1150 series foam seal provides a 100% watertight seal. This system is excellent for roof applications and installation under metal cover plates. Its ridged sides trap and pool epoxy providing superior adhesion to the joint surface and a water tight seal. The 1175 series foam seal is UV stable and resistant to solvents and fuels which are commonly found in parking garages and other roadway surfaces. The open cell foam is constantly self-expanding, allowing system to maintain a watertight seal during rapid joint movement.
