•Dropping method of MICP was introduced for crack-healing in mortar.•MICP agent was dropped on cracked mortar to improve strength and water tightness.•CaCO3 biomineralization can reduce crack area up to 85% after treatment.•Compressive strength of treated mortar was 43% higher than that of cracked s...
