Balcony waterproofing
Alchimica has developed three main flooring solutions for balconies and/or terraces. Each of them is based on the same primers and polyurethane waterproofing membranes of the Hyperdesmo system. The difference is in the decorative finish of the external floor. Therefore, we propose a decorative finish:
- Obtained using Hyperflakes decorative flakes (available in numerous color variants), with a final closing coating (so-called top-coat) in a satin or glossy version,
- Obtained using a colored decorative aggregate bonded with a colorless Hyperdesmo-T polyurethane resin and finished with a satin or glossy sealing coat,
- Obtained by making a stone carpet based on natural marble cobbles bonded with Hyperdesmo-T polyurethane resin (horizontal surfaces) and Hyperdesmo-T Vertical (vertical surfaces such as plinths).
The arrangement of layers is presented in the illustrations below:
Balcony waterproofing
The balcony and its advantages are a key issue for the design of our house, apartment or company building . Remember that irregularities in its construction, e.g. improper waterproofing of the balcony, affect the solidity, durability and strength of the entire building structure . The balcony is in contact with the walls of the building, is located above its specific spaces, and thus determines whether it is dry or humid inside, whether there is no environment for the development of microorganisms, whether it is warm or cold in the home space, etc. Therefore, it is worth taking care of the technical aspects of securing the balcony surface, such as the aforementioned importance of good waterproofing of the balcony, and at a later stage, a specific plan for its decoration and taking care of the aesthetics of the balcony .
Balcony waterproofing - take care of your relaxation area
The most important rule when waterproofing a balcony is to select the right products for the size of the balcony surface and its location (what surface is it above – above ground or above other rooms of the building) . Remember that the larger the balcony surface, the more flexible the materials used for waterproofing should be. Greater flexibility of the applied materials ensures that the material reacts to all stresses in the structure and protects against cracks and gaps in the surface, especially at the junction of the horizontal surface with the walls. Any damage or damage to the balcony substrate is a risk of water getting in and stagnating, and in winter, freezing and bursting of the structural slab, e.g. concrete. Highly flexible products, unlike rigid ones, mask all cracks resulting from natural stresses in the structure and protect against water and moisture getting into them. At the stage of balcony construction, remember to seal the balcony under the tiles on the structural slab with an appropriate product: the most commonly used is mineral insulation (i.e. cement mortar with polymers), insulating mats under tiles or an innovative and extremely practical approach: resin insulation, which is briefly described below.
