"We are Sika Liquid Plastics. We are pioneers of liquid roofing membrane technology and leaders in cold applied roofing systems."

As a British based manufacturer, quality and innovation are just two of the characteristics replicated throughout Sika Liquid Plastics – visible in our products (such as our flagship products Decothane and Sikalastic), our people, our manufacturing processes, and our research and development.

Since 1963 we have produced an extensive range of high performance, technologically advanced liquid applied coatings and waterproofing membranes for the protection and waterproofing of roofs and balconies. Our products are leaders in their fields because of their unique properties and ability to outlast and outperform traditional counterparts. We also supply a complete range of cold applied built-up liquid roofing systems including warm roofs, inverted roofs, green roof and solar roof finishes.

As a member of the Sika worldwide group of companies the demand for our products stretches across the globe, and our systems have been installed on many successful projects in the UK, Europe, Middle East and USA.

We are leading the way with innovative products for the future, as the construction industry evolves towards safer applications and protection systems with design lives as long as the building itself.
