To fill the expansion joint between foundations, special sealants or tape materials are usually used, which provide flexibility and the ability to compensate for deformations and movements between adjacent foundations. Below are some of the common materials for filling expansion joints between foundations.
Elastomeric sealants
Elastomeric sealants are flexible polymer-based materials that can easily deform to accommodate movement and expansion between foundations. They provide tightness and protect against the ingress of moisture and dirt.
Polyurethane mastics
Polyurethane mastics also have high elasticity and tightness. They are well suited for filling expansion joints between adjacent foundations, especially in heavy-duty construction projects.
Epoxy resins
Epoxy resins provide high strength and good adhesion to concrete. They can be used to fill expansion joints in projects where a particularly high load capacity is required.
Thermoplastic tapes
Thermoplastic tapes are a material that is glued into expansion joints on a special epoxy compound. They provide complete tightness of expansion joints between foundations, and also have high strength and wear resistance.
When choosing a material for filling an expansion joint between foundations, it is necessary to take into account environmental conditions, the type of foundations, loads and other factors. It is recommended to consult with engineers or construction specialists in order to choose the most suitable material and correctly perform the process of filling the joint.
