§1What this business is

A service team that finds where water is getting in and seals it — terrace chemical coatings, external wall sealers, damp-proofing, water-tank lining, expansion-joint sealing and epoxy injection into cracks. Work comes from home owners, property managers and builders on subcontract. The profile also suggests becoming a dealer for a waterproofing product brand.

Capacity: Service income ₹15.00 L a year at full capacity; ₹9.00 L in year 1 at 60%.

§2Is it right for you?

Who it is for

Someone from civil work, painting or construction who can judge why a structure leaks.

Who it is not for

Someone who wants a desk business — this is site work on roofs, tanks and basements.

Advantages

  • Every monsoon brings fresh leak complaints
  • Small machinery cost; no factory needed
  • Repeat work from housing societies and builders
  • Can add income by selling a brand's waterproofing chemicals

Drawbacks

  • A failed job means unpaid bills and lost reputation
  • Work slows outside the pre-monsoon season
  • Many untrained applicators quote low prices
  • The profile shows losses in the first two years

Skills you need

  • Finding the source of a leak

Why difficulty 2/5: Low investment, but results depend on site skill and the guarantee you give.
