Fondaline
Protection of Basement Walls and Foundations
DESCRIPTION: The underground parts of buildings must be protected against damp and ground water. This is not only necessary for a comfortable use of the building but also for safety reasons. Humidity leads to the corrosion of the steel.When rust affects the reinforcement of the concrete the structure system is also damaged and this can be dangerous for the stability of the building especially in critical situations like earthquakes. Therefore, foundations and basements have to be waterproofed.
Moreover, the waterproofing materials are very sensitive. If not properly protected, they are under the risk of being damaged during the back-filling of the building site. Fondaline’s tough but flexible body absorbs mechanical impacts of ground parts like stones and gravel and prevents any such damage on the waterproofing layer even if they might hit the wall. Furthermore the air gap created by Fondaline’s naps links the ground water to the drainage tube on the bottom. In places where there is no risk of ground water, Fondaline is also efficient if it is used as a single layer for damp proofing. During the life-time of the building Fondaline continues to protect the underground walls also against the attacks of roots and most chemicals which might be harmful for underground building parts.
APPLICATION: Fondaline has to be placed so that the black side touches the wall, the brown side the soil. Rolls can be applied horizontally or vertically depending on the depth of the building. Overlaps of 10 cm are necessary.
Until the back-filling the position of Fondaline has to be fixed so that no damage occurs on the waterproofing by any kind of fixing element. For this purpose the system consisting of self adhesive nails and washers can be used. If needed, the system can also be combined with hard-board insulation panels like XPS or EPS.
Fondaline can be nailed directly to concrete only on levels where there is no risk of infiltration of damp or ground water.
