FONDALINE provides protection for basement walls and foundations where groundpressure may damage waterproofing layers.
FONDALINE, made of high density polyethylene is used for the draining of ground water and the protection of the underground waterproofing systems against damages caused by ground pressure.
FONDALINE’s strong and flexible naps resist against the mechanical impacts caused by the back filling of the ground any kind of damage on the surface of the waterproofing layer.
Ideal for All Kinds of Drainage
The air gap created by the naps of FONDALINE between the ground and building parts like basement walls or floors is ideal for all kinds of drainage.
FONDALINE provides solutions against damages caused by damp and humidity. If FONDALINE is applied together with a new layer of plaster or gypsum board, the final surface of the wall remains clean and smooth. Combined with openings for ventilation on the floor and ceiling level the air gap created by FONDALINE between the new finishing and the existing wall helps also to the evaporation of the damp.
The underground part of buildings must be protected against damp and ground water. This is not only necessary for a comfortable use of the buildings 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 dangereous for the stability of the building especially in earthquakes. Therefore foundations and basements have to be waterproofed.
The naps of FONDALINE resist against compressions between 120-220 kN/sqm keeping continuously an air gap of 5,8 l/sqm between the walls or floors of the building and itself.
This space is big enough for the drainage of the rain or ground water, as well as for the evaporation of humidity if supported with a suitable system of ventilation. In the underground parts of the building there is also the problem of the compression caused by the soil leaning to the basement walls. FONDALINE’s 1200-1600 naps by sqm provide a homogenous distribution of the ground pressure and do not allow any mechanical damage on the surface of the waterproofing materials.
FONDALINE is recommended by the details of the specification TSE 11758-2, which was developed for asphalt membranes by TSE, as a "drainage ensuring material, protective layer."
FONDALINE is multifunctional:
Protection of Basement Walls and Foundations
The underground 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 though but flexible body absorbs mechanical impacts of ground parts like stones and gravel and prevents any such damage.
During the life-time of the building FONDALINE continues to protect the underground walls also against the attacks of roots and most chemical which might be harmful for underground building parts.
Internal Repair of Wall Damages Caused by Damp and Humidity
If basements are not correctly waterproofed from outside, the walls get moudly and the damage of the humidity cannot be repaired by repainting or plastering from inside.
If FONDALINE is applied together with a new layer of plaster gypsum board, the final surface of the wall remains clean and smooth. Combined with openings for ventilation on the floor- and ceiling level the air gap created by FONDALINE between the new finishing and the existing wall helps also to the evaporation of the damp.
Internal Repair of Floor Damages Caused by Damp and Humidity
FONDALINE is the ideal material for the internal damp-proofing of floors, because it can resist not only against humidity, but also against vertical loads, as FONDALINE's 8 mm high naps do not squash down. So, a continuous air gap is provided between the existing- and new floor, which can also be ventilated at wall flashings.
Protection of Ground Slabs Against Humidity Coming From The Ground
The concrete is well protected if FONDALINE is laid loosely on the compressed ground. The system is also safe against mechanical damages, as the loading capacity of FONDALINE is over 25 tons/sqm.
