    Plastic cellars without the need for concreting.

    Own cellar,

    done in 1 day!

    In today’s uncertain times full of fears for the future of us and our children, we need to think ahead.

    What other pandemics and viruses will follow?

    How many of us will be in quarantine?

    Will there be anything to eat?

    Will there be shopping?

    You really need to think ahead and keep your own supplies on your property properly and safely!

    Having your own safe cellar full of food is a must nowadays!

    Kolomaki Kellari 5 and 7 cellars are not as expensive as conventional concrete cellar construction.

    For example, the most popular Kolomaki Kellari 7 cellar, including a “turnkey” installation, can be purchased in one day for a maximum of CZK 150,000. Kolomaki Kellari 5 comes out even cheaper.

    This is the best thing you can buy at the moment to stock up on the next quarantine!

    The easiest installation of a self-supporting cellar without a building permit is a really quick solution to our problems. We will arrange the installation “turnkey”.

    We have cellars in stock for you, you can have them in the garden tomorrow.

    A certificate for contact with food and drinking water is a matter of course in every cellar.

    The purpose of the store

    Kellari cellars are designed for use as storage space for food and liquids at a constantly low temperature, for placing technological and other equipment in an enclosed space below ground level.

    Kellari cellars are designed for installation underground.

    Product description and specifications

    The working chamber has the shape of a vertical cylinder of various diameters mounted on a flat surface. The wall of the working chamber is made of homogeneous polypropylene with a thickness of 8 mm by the butt welding method. The double-layer base of the working chamber is made of polypropylene Quatro boards and homogeneous PP boards with a total thickness of 88 mm.

    The working chamber cover is made of lightweight polypropylene with a thickness of 8-10 mm, reinforced with connecting elements. An inlet neck is installed on the overlap. The base and the overlap of the working chamber are welded to the working space by extrusion welding.

    Profiled storage shelves, tubes, vents and wine racks create an inner frame and eliminate external loads. The police and the ventilation tubes are connected to each other and to the cellar body by welding.

    The entire cellar is equipped for operation in high humidity conditions and does not require special treatment.

    The user enters the cellar using stairs made of a combination of polypropylene and aluminum steel for safe movement.

    Cutting of parts and the most important welded assemblies is performed on automatic CNC machines.
