How terrace waterproofing is priced
Terrace waterproofing is usually priced per square foot of terrace area, plus extra for repairs like crack filling, re-sloping or replacing broken tiles. The method chosen has the biggest effect on the rate.
Common methods and where they fit
- Cementitious coating: economical and quick. Suits terraces in good condition with few cracks.
- Acrylic or elastomeric coating: flexible and UV-resistant, bridges hairline cracks. A popular choice for exposed terraces.
- Polyurethane (PU) coating: highly flexible and durable, good for terraces with movement or recurring cracks.
- Membrane systems: sheet membranes for larger or heavily damaged roofs, usually with a protective layer on top.
- Heat-reflective top coat: often added on top to reduce heat in top-floor rooms.
What increases the cost
- Many cracks or a broken screed that must be repaired first.
- Poor slope that lets water stand — re-sloping adds material and labour.
- Old failed coatings or tiles that must be removed.
- Parapet walls, pipe outlets and corners that need detailed treatment.
- Longer warranty periods, which need better materials and more coats.
How to compare quotes fairly
Ask each contractor to name the product, the number of coats, how they will treat cracks and joints, and the written warranty period. The cheapest quote often skips surface preparation or corner detailing — the two places where terraces usually leak.
When to do it
The best time is the dry season, between November and May. Coatings need a dry surface and dry weather to bond and cure properly. Booking well before June also avoids the pre-monsoon rush.

Frequently asked questions
How long does terrace waterproofing last?
It depends on the system and preparation. Good acrylic or PU systems typically last several years, and the exact warranty should be written into your quote.
Can waterproofing be done over existing tiles?
Sometimes, using systems designed for tiled surfaces, but loose or hollow tiles must be fixed first. A site inspection decides this.
