Sika Liquid Plastics manufacture elastomeric seamless polyurethane coating systems that are suitable for the waterproofing of new and the refurbishment and upgrading of existing cold flat roofs.


Sika Liquid Plastics liquid applied membranes are high performance polyurethane coatings, which rapidly become resistant to rain damage. They cure to form a completely seamless, elastomeric membrane. Each system is fully reinforced with Sika Reemat Premium glass fibre matting. Systems are available to suit all client’s budget requirements and are available with 10, 15 and 20 year waterproofing guarantee’s.


Most balconies and walkways are constructed from concrete with an asphalt waterproofing membrane. Without any protection these substrates will inevitably crack and erode. There are a range of systems specifically designed to protect balconies and walkways against the challenges presented by the elements.

The systems incorporate a unique waterproofing membrane Decothane /618 Balcons – a high performance waterproofing solution that utilises a moisture-triggered curing system. The balcony systems can be installed over most existing surfaces, eliminating the costs and inconvenience associated with breaking out and disposing of the old material. And also offers an anti slip capability.

Balcony 10 Waterproofing system provides reinforced waterproof protection for walkways, balconies, and terraces guaranteed for 10, 15 and 20 years.
