Green roofs from a waterproofing perspective Waterproofing – Every successful green roof system is built upon a sound waterproofing foundation. Selecting a waterproofing manufacturer and roofing system you can trust are essential to give long term, guaranteed performance. Through its high profile brands, IKO PLC has a rich heritage in the design and installation of waterproofing systems, dating back over a century. The company has built up its reputation on close working relationships with specifiers, contractors and clients in the public/ private sectors, on extensive new build and refurbishment projects. We offer the most comprehensive range of selected waterproofing systems compatible with green roof finishes. Ensuring that exactly the right product is specified for the right project, no other manufacturer can provide such a diverse product offer. Our high performance systems include:

Green roof finishes, once installed, can make it very difficult to identify and repair leaks in a waterproofing membrane. That’s why it is important to get the whole system right first time. And that’s why IKO is the right choice. 5
