Скачать или смотреть Top 3 Waterproofing Fails in 2025: Bonding Plaster, Podium Decks & Parapet Walls EXPLAINED

These 3 are Crownstone’s greatest hits of 2025

🚫 Bonding plaster

STILL being slapped onto walls in old buildings. It’s been top of the charts for 20+ years… because it’s wrong.

Always has been.

It’s a modern plaster and doesn’t belong in heritage properties. One day, maybe, people will stop using it!

🏗️ Podium decks

The most misunderstood bit of any building, a podium deck is not a roof.

We spend a huge chunk of our time exposing failed podiums and starting from scratch.

🧱 Parapet walls

That extra bit of wall sticking up above your roof? It’s like a sponge for weather.

Once it goes porous, water doesn’t ask permission before heading down into your structure.

People forget: if the top of your building sticks out, that needs weather and waterproofing too.

Let’s see if they make next year’s chart…

(I really hope not!)
