Low-emission under-tile waterproofing to protect the fabric of buildings

Long-term protection for the fabric of buildings is the objective of any building owner. This topic is a top priority especially in connection with tiling and natural stone coverings in wet rooms. DIN 18195 issued in 2011 defines wet rooms as “interior rooms exposed to so much water as a result of use that a floor drain is required.”

If the bonded waterproofing under the tiles in wet rooms is inadequate, moisture may penetrate the substrate, causing severe damage, as a result of exposure to large quantities of water. The consequences include mould, damage to the building fabric and an unhealthy interior climate. You can prevent this scenario by professional waterproofing work using low-emission waterproofing products from the PCI range.
