Parapet & Sidewall Waterproofing

Uniflash membrane to stop water entering at the cap and side walls.

— Service Overview

Parapet & Sidewall Waterproofing done properly — once.

Parapet walls and sidewall flashings are exposed on all sides and bear the brunt of Cape Town's wind-driven rain. We seal the cap, the joint, and the wall face with a continuous Uniflash membrane and finish with rubberized paint so water has nowhere to enter.

— FAQs

Answers from our team.

Common questions about parapet & sidewall waterproofing in Cape Town.

Do you need to remove the existing coping stones?

Usually no — we work around them. If they're badly damaged we replace them as a separate quoted item.

Can you waterproof a parapet that is already painted?

Yes, but the failing paint must be properly prepared first. We cost this into the quote.

How wide should the membrane be?

Minimum 300mm onto the roof deck and full coverage over the cap — we never cut corners on lap width.
