When should terrace waterproofing be done before monsoon?

Ideally 2-3 weeks before Hyderabad's monsoon onset, which normally falls around June 9. In practice this means starting work anytime from April through mid-May to allow enough dry weather for full curing.

How much does terrace waterproofing cost?

In Hyderabad, terrace waterproofing typically costs Rs 35-150 per sq ft depending on the method and terrace condition, with existing damaged slabs costing more (Rs 145-170/sq ft) than new or well-maintained surfaces.

Can terrace waterproofing be done over old coating?

Only after inspecting the old coating for adhesion failure, cracks, and ponding history. Failing sections need to be stripped back to bare concrete rather than coated over, or the underlying problem just gets sealed in rather than fixed.

How long does terrace waterproofing take to dry?

Most systems need 2-7 days of dry weather to fully cure, depending on terrace size and the method used, which is why starting well before monsoon onset matters.

What causes terrace leakage after waterproofing?

Most post-application leaks trace back to inadequate surface prep, insufficient cure time, unresolved slope or ponding issues, or untreated parapet and expansion joints, rarely a failure of the waterproofing material itself.

Is terrace waterproofing needed every year?

No, a properly done system typically lasts 5-10 years. What's needed every year is a pre-monsoon inspection to catch small issues like cracks, blistering, or ponding before they turn into active leaks.
