Which Waterproofing System is Right For You?
If your building is like most, it has critical interior areas that must be protected from the damaging effects of water, moisture or other contaminants. If these areas are covered with soil, landscaping, pavers or concrete/pavement, it is extremely costly and challenging to remove the overburden and determine the cause should a leak occur. As a result, one of the most important decisions you have to make is the waterproofing system.
Sika Sarnafil’s superior PVC membrane waterproofing systems are used on horizontal grade applications such as plaza decks, green roofs, balconies and planters.

The Chicago City Hall vegetated “green” roof, as seen in the below photo, is protected by Sika Sarnafil’s Loose-Laid System. As Chicago’s first green roof project, the City wanted to be sure that its roof deck has long-term protection from root growth, heavy overburden, algae and insects. They chose Sika waterproofing because of its proven performance track record of more than 30 years protecting green roofs throughout Europe.
