Balcony waterproofing is an essential intervention to prevent structural damage caused by water and moisture. A balcony exposed to the elements without proper protection can develop cracks, coating detachment, and seepage that compromise the stability of the building and the quality of the rooms below. Let's see what are the best solutions for effectively and durably waterproofing a balcony.
Balconies, like terraces, are constantly exposed to rain, snow, temperature changes, and UV rays. Without proper protection, water can seep into floor cracks or joints between the slab and the wall, causing:
To avoid these problems, a suitable waterproofing system must be applied, choosing from the most innovative and effective solutions available on the market.
For newly constructed balconies, an effective solution is the use of crystallizing admixtures such as Drymix and Drymix Ultra, which are added directly to the concrete mix. These products react with water to form insoluble crystals that seal pores and micro-cracks, preventing the passage of moisture.
Advantages:
For existing balconies, liquid or cementitious waterproofing membranes can be applied, creating a continuous and flexible barrier that prevents water absorption.
Types of membranes:
These solutions can be applied directly under the existing floor or before new tiles are laid.
Bituminous membranes are a traditional solution for waterproofing balconies, providing effective and long-lasting protection. They are applied hot or cold and then covered with a protective layer or paving.
Advantages:
If you do not want to dismantle the existing flooring, you can apply a transparent water-repellent silane or siloxane-based waterproofing agent. This treatment creates an invisible surface protection that prevents water from seeping into joints and micro-cracks, without altering the appearance of the floor.
The choice of waterproofing system depends on several factors:
To ensure effective and long-lasting results, it is advisable to rely on high-quality materials such as those offered by Drykos, which offers advanced solutions for waterproofing concrete structures.
Balcony waterproofing is an essential intervention to prevent damage from seepage and ensure the durability of the structure. Whether the balcony is new or existing, there are effective solutions such as crystallizing additives, liquid membranes, and bituminous sheathing. Choosing the right method can protect the building, avoid costly repairs, and improve living comfort.
