A method and structure for providing a resilient seal system in the gap or joint between adjacent construction panels utilizing a foaming expansive elastic closed-cell liquid-impermeable sealant, a backer rod and a seal. The foaming expansive elastic closed-cell liquid-impermeable sealant is first introduced to the gap or joint between the adjacent construction panels. A seal is introduced into or over the gap after the foaming expansive elastic closed-cell liquid-impermeable sealant has sufficiently cured. In alternative embodiment a backer rod is located intermediate the sealant and seal as a spacing member.
