Rooftop parking

Rooftop parking is an effective way to use space in urban environments, which requires design taking into account all the necessary factors to ensure safety and comfort for users. The pedestrian zone on the roof of the parking lot can be decorated in the form of a square or a green area equipped with benches and flower beds. It can be used for walking, sports, recreation or for organizing events.

When designing a pedestrian zone on the roof of a parking lot, it is necessary to take into account the weight of the load that will be on the roof. For this purpose, rigid structures made of reinforced concrete or steel are used, capable of withstanding the necessary load.

Waterproofing of a parking lot with rooftop parking is very important, since such structures are at increased risk of water penetration.

Special materials are used for waterproofing the parking lot, which provide reliable protection against water penetration. To do this, you can use membranes made of polymer materials, such as PVC, NDPE, bitumen membranes or waterproofing films.

The spiked membrane SNTDRAIN EKL400 is a rolled material made of high-density polyethylene (HDPE), with spikes over the entire surface and a density of 400 g / sq.m. The principle of operation of the drainage membrane is that due to its spiked shape, the drainage membrane creates a protective layer that promotes the removal of water and moisture, does not allow it to be damaged applied waterproofing, as well as evenly distributes the load on the surface of the canvas.

Choosing a spike-shaped membrane for the concrete base instead of a rough layer (skinny concrete), they focus on the operational loads of the concrete slab. The arrangement of the operated roof is designed for pedestrian loads, therefore, the drainage membrane is chosen with low technical characteristics, namely 400 gr / m.kv with geotextile

The spiked membrane in the blind area system and the exploited roof is laid with spikes and geotextile outside.

Technology of laying of the operated roof with a spike membrane:Lay a clay-gravel layer with a slope on the floor slab

•  
• Pour a cement-sand screed on top
• After the screed solidifies, apply a layer of waterproofing
• On top of the waterproofing layer, lay the insulation made of extruded polystyrene foam
• Spread the rolls of the spiked membrane with geotextile over the entire surface of the geotextile upwards
• Connect the rolls together with an overlap of 10 cm. Glue the overlap seams with butyl rubber tape with Aqua Protect K-2 sealantThe finish coating should be laid last.
• The finishing coating means a green roof, paving slabs, covering for sports grounds, crushed stone, gravel, polymer coating.

A pedestrian zone on the roof of a parking lot can be useful in cities where there are not enough green areas and places to relax. It can also be used to create a more pleasant and comfortable living environment and a visiting area for residents of the house or office visitors.

Needle-punched geotextiles of different densities are actively used to arrange lawns and green lawns with plants in open parking lots and roofs. Geotextile fabric is very strong and elastic, does not lose its properties and continues to perform its functions perfectly. Geopolotno is stable under changing weather conditions, does not rot, does not decompose, does not respond to the effects of microorganisms, bacteria, acids, alkalis, insects, counteracts the appearance of mold, fungi, roots. Because of its structure, geotextile easily passes steam and air. This allows you to maintain a favorable temperature and humidity for plants.

When waterproofing a building with an operated parking on the roof, it is necessary to protect the roof itself. For this purpose, the same materials are used as for waterproofing an underground garage.

Teknomer 200 EX Crystallized is a two–component, elastic crystallized waterproofing mixture consisting of a cement-based dry mixture with special additives (component B) and a liquid polymer (component A). Forms a flexible waterproofing vapor-permeable coating with high resistance to positive and negative water pressure and is used for both internal and external application on horizontal and vertical surfaces.

In addition to choosing the right material for waterproofing, it is also necessary to take into account the design features and the risks of possible water penetration in the future. For example, if there is a possibility of flooding of a building or roof, it is necessary to provide appropriate protection measures, such as the presence of drainage systems and drainage systems.

It is also important to regularly carry out maintenance and check the condition of the waterproofing in order to detect and eliminate possible damage in a timely manner.

It is important to make sure that all seams and joints are sealed and do not allow water penetration. To do this, a thermoplastic HYDROFLEX membrane tape is used with great success. It is used for horizontal and vertical expansion joints in parking lots, underground structures, basements and semi-basements and is designed for waterproofing cold joints.  The chemical composition provides high elasticity and adhesion to dry and wet concrete. Hydroflex thermoplastic tape is resistant to aggressive effects of fuel oil and oil, adapts to use in a wide temperature range together with Hydroflex adhesive sealant.Rooftop parking can be useful in cities where there is not enough space for parking on the streets, or in cases where it is necessary to use the space on the territory as efficiently as possible.

An important aspect in the design of parking on the roof is also the environmental side. For example, you can install systems to collect rainwater and use it for watering green spaces, or install solar panels to generate electricity.
