Loose Laid Membrane Systems with Sikaplan / Sarnafil

Sika has a proven track record of over 30 years with green roof construction. All of the Sikaplan and Sarnafil waterproofing membranes used in these systems are:

• Resistant against biological and micro-organisms
• Fully resistant to root penetration

Efficient application is also a key advantage of these materials:

• These single ply membranes can be installed in most weather conditions, even at minus temperatures. This gives a unique flexibility to contractors, their clients and designers.
• Loose laying of the membranes provides fast waterproofing layer installation
• Soil with a minimum weight of 80 kg/m² provides the necessary wind uplift resistance, eliminating the need for any additional mechanical fastening

Liquid Applied Membrane Systems with Sikalastic

The Sikalastic  liquid applied membranes are also ideally suited to green roof systems. In addition to the normal SikaRoof  MTC system advantages, there are many other benefits:

• These systems have full surface adhesion to the substrate, eliminating the risk of lateral water flow under the waterproofing system, so that any potential leaks from future damage can not spread along the roof surface and therefore they can easily be identified and re sealed.
• Fast machine application and curing with 2-component PU materials
• All Sika’s liquid membranes used in green roof construction have excellent root and micro-organism resistance
• The products can be applied directly on to prepared concrete decks and so they are ideal for inverted roof build-ups
