Permanent parking space shortage is very pronounced in urban areas. A parking level is a building fit for traffic (garage, basement garage) and allows space-saving parking of vehicles or other transport above the other in several floors. Therefore, the pavement (asphalt, concrete, etc.) and the seal must be perfectly coordinated.
In navigable areas with adjacent land use, insulation should also be considered. Bitbau DÖRR has a wide product range, where functional system solutions will be implemented in the area of parking levels.
In this type of roof construction is the roof sealing below the insulation and is well protected from all external influences. This circumstance has a positive effect on the aging behavior and thus on the life expectancy of the waterproofing sheet.
Further, for this type of construction XPS insulation is required due to its moisture and pressure-resistance.
For concrete surfaces such as a parking level you have a variety of design options.
Between protected concrete and waterproofing sheet are drain and overlays to be installed so that water is derived safely and common shrinkage and creep processes are collected within the concrete layer.
Rolled asphalt as a widespread scale layer in road construction is often used in parking level surfaces. Ideally, a cover layer and asphalt protection is applied.
Special bituminous sealing materials guarantee the temperature stability during installation of rolling asphalt, where temperatures of up to 160°C impinge.
Mastic asphalt in parking level surfaces is a popular, useful covering layer and constitutes a sealing layer . Thus, water is drained quickly and safely.
Special bituminous sealing materials guarantee the temperature stability during installation of the mastic asphalt, where temperatures of up to 250°C impinge.
