The benefits of flexible polyurethane sealants in active cracks for controlled movement.

Regardless of crack width, polyurethane sealants are suitable for the treatment of small or larger cracks as they form a permanent, tough and elastic seal.  Moreover, they satisfy the major requirements for crack filling by being fast curing and having strong adhesion, strength, high elongation properties, good workability, stability and long-term performance. ALCHIMICA’s advanced polyurethane technology sealants offer excellent bonding to clean concrete.
