DEKS makes one thing well: the seal where a pipe passes through a roof.
The stepped cone was developed in Melbourne in 1989 and has been refined against real roofs ever since. Compounds are mixed and moulded in-house, tested against UV, ozone and thermal cycling, and specified on commercial and residential roofs in more than fifty countries.
DEKS North America opened in Elk Grove Village, Illinois, holding US stock in US sizes so a contractor is not waiting on a container.

Made, not assembled
Compounds are mixed in-house and moulded on our own tooling, so the cone that ships is the cone that was tested. Every batch is traceable to the mix.

—UV, ozone and thermal cycling tested to international standards
