What Is APP Waterproofing Membrane?
APP Membrane (Atactic Polypropylene) is a professional-grade waterproofing solution made from polymer-modified bitumen. When it comes to keeping water out of a building, you need more than just a decent roof — that's where our Insutech APP membrane comes in.
At Deco Roofing Systems, we supply and install this membrane because we have tested and proven it over years: it's a thick, flexible bitumen sheet that doesn't crack or peel easily, even under East Africa's harsh sun and heavy downpours. You can trust it on flat concrete roofs, pitched roofs, or swimming pools — wherever you need waterproofing that lasts.
Why "APP" Matters
The "APP" in APP Membrane stands for Atactic Polypropylene — a polymer that modifies traditional bitumen to make it more flexible, more durable, and more resistant to temperature changes. Unlike standard bitumen which can become brittle in cold weather or soft in extreme heat, APP-modified bitumen maintains consistent performance across Kenya's varied climate zones.
Thanks to its polymer-modified bitumen base, the sheet resists tearing, stretching, or shrinking — even if the building shifts slightly over time. This makes APP membrane the go-to waterproofing solution for professionals across Kenya.
