Hydrotech Monolithic Membrane 6125

We're proud to announce HydroTech, an experienced and highly regarded liquid membrane manufacturer, is now part of Sika. The acquisition strengthens Sika’s roofing and waterproofing portfolio, and complements Sika’s sustainability focus.


As the market evolves and more rooftops become premium outdoor spaces, this partnership allows us to offer even greater opportunities for you. Hydrotech’s sustainably formulated membranes—containing up to 40% post consumer recycled materials—fit perfectly within Sika’s long term sustainability strategy and commitment to durable, high performance roofing and waterproofing solutions.


You can continue to rely on Sika for full local support across specification, technical assistance, training, and delivery. If you have any questions or would like to discuss your next project, please reach out to Jeff Perrett, Sika Market Field Manager - Roofing & Waterproofing.
