Depending on the condition of the existing membrane, this system can be installed directly over the existing failed membrane, substantially reducing the overall project costs and risks associated with removing existing membranes and exposing the existing structure to water damage during this process.
The Fatra fully adhered system is bonded directly over the existing system using the Fatrabond moisture curing polyurethane adhesive. The Fatrafol 807 has a 300gsm fleece backing which provides protection to the Fatrafol membrane from any potential contaminants in the existing failed membrane.
The Fatra fully adhered system is unaffected by substrate moisture and inclement weather conditions during installation, unlike liquid applied membranes which can delaminate & defect prematurely should the substrate have a high level of moisture content. All joints, laps and terminations are hot air fusion welded creating a permanent and physical bond and does not rely on adhesives sealants or tapes to create a waterproofed joint. The Fatrafol 807 provides unrivalled shear and tear resistance so should the system ever be exposed to structural cracking or excessive structural movement, the Fatrafol membrane will remain intact
The Fatrafol 807 has a 300gsm fleece backing which enables the PVC membrane to be fully adhered directly over the existing failed membrane. The thicker fleece backing provides adequate protection to the PVC membrane to avoid impairing the performance of the Fatra membrane.
The Fatrabond 1215 moisture curing polyurethane adhesive is used to bond the Fatrafol 807 PVC membrane directly to the existing membrane. The Fatrabond adhesive is unaffected by the substrate moisture or inclement weather improving productivity and reducing overall installation programmes.
Fatra Australia supply a unique primer which is applied directly to an existing single ply membrane which enables the Fatrafol membrane to be directly adhered onto the existing membrane. Consultation with a Fatra Technical representative is advised.
