The BBA-Certified Waterproofing System That Simplifies Everything

Purtop Easy, manufactured by Tecnopol (part of the Mapei Group), is fully BBA-certified (certificate 23/7057) with a BROOF(t4) fire rating and a certified 25-year service life under ETAG 005.

Tired of Over-Complicated Waterproofing Systems?

Multiple components, specialist equipment, delayed schedules—it all adds time and risk to your project.

Purtop Easy changes that.
A one-component, ready-to-use liquid membrane that goes from pail to substrate

no mixing errors, no primers (in most cases), and no compromise.

Whether you're waterproofing a green roof, podium deck or flat roof refurbishment, this system delivers speed, certainty, and certified performance.


Where to Use Purtop Easy

Versatile, flexible and approved for use on:

  • New build and refurbishment flat roofs

  • Terraces, balconies, podium decks and walkways

Suitable substrates (no primer required when sound and clean):

  • Concrete

  • Cementitious screeds

  • Ceramic
