We are seeking long-term and economical solutions for avoiding vegetation growth over external surfaces of buildings.
City infrastructure & utility companies are responsible for providing services such as upkeep of the building, and maintenance of several housing units. A typical city may consist of several thousands of housing units spread over 60+sq. km area. These units are up to 45 feet in height. The external surface of these buildings is either concrete or cement-sand plaster, lime-sand plaster, or surkhi-lime plaster.
Vegetation growth over the external face of these buildings has been a persistent problem. Most of the vegetation found are Pipal, Banyan, ferns, and algae. The effects of vegetation growth are listed below:
- Seepage in buildings resulting from the penetration of vegetation roots inside the structure walls.
- Structure damage: damage to columns, walls, beams, etc.
- Utility damage: Choking and damage to the soil pipe, water line, rainwater downcomer pipes, etc.
- Financial loss due to frequent repair and maintenance.
- Resident dissatisfaction due to reoccurrence of vegetation growth.
- Spoils the aesthetic view of the buildings.
Even after treatment using bleaching powder solution, solution of copper carbonate and liquid ammonia, etc., accompanied with external repair and & maintenance, there is a reoccurrence of vegetation growth after 3-5 months. Hence, we require a long-term and economical solution to check vegetation growth over external surfaces of buildings.
