RESULTS FOR SEALANT FOR CONCRETE


Most joints and some cracks in concrete structures require sealing against the adverse effects of environmental and service conditions. The introduction of joints creates openings that usually must be sealed to prevent passage of gases, liquids, or other unwanted substances into or through the openings. In certain applications, secondary functions are to improve thermal and acoustical installations, damp vibrations, or prevent unwanted matter from collecting in crevices. Sealants must often perform their prime function while subject to repeated contractions and expansions as the joint opens and closes, and while exposed to heat, cold, moisture, sunlight, and sometime aggressive chemicals.
