Waterpoof limestone retaining wall?

[PscottDIY]

Hi Team, re: my recent retaining requirement we bit the bullet and had some nice limestone walls built. Now my question what’s the best/ easiest way to waterproof behind the walls ? I ideally don’t want to have to deal with messy bitumen paint but will if I have to. 🤷‍♂️ 🙏

Hi @PscottDIY,

I'd recommend using Crommelin 15L Blackseal Heavy Duty Bitumen Waterproofing Membrane. It's a water-based bitumen that is far less potent smelling, or messy than older types and has an easy clean-up in water.

Ensure the wall is free from dust before application to ensure it binds correctly.

Please let me know if you have any questions.
