“Where’s the Beef in Joint Sealants?”
“What if you develop a sealant that uses the best features of both liquid sealant and impregnated foam sealants AND eliminates their weaknesses?”
Hybrid sealants available today shine in many applications including:
1) movement joints,
2) large joints over 25mm (1- inch),
3) where resilience or the need to resist air-pressure and thermal differentials is essential,
Under development throughout the world, other hybrids include:
anywhere a structural or new to-existing gap needs filling and sealing combinations of chemically-resistant liquid sealants and impregnated foam sealants for use in wastewater, caustic and other harsh environments;
2) combinations of materials to provide fully fire-rated, watertight movement joints;
3) combinations of hydrophilic or hydrophobic materials with impregnated foam sealants to handle below-grade and head of-water applications.

“All hybrid foam joint sealants rely on the proper function of the
impregnated foam sealant.”
Laminated foam composite materials often lead to this
question:
