WATERPROOFING THE FLOOR OF THE BALCONY OR TERRACE
Water infiltration represents one of the main problems for those who own a balcony, a terrace or a tiled patio.
Exposed to the weather all year round, in fact, these structures are subject to natural degradation. In particular it is very common the loss of waterproofing of the flooring that can cause extensive damage.
In order to avoid risks, it’s necessary to carry out regular checks and immediate intervention at the first signs of cracks or breaks. It’s necessary to act promptly, first of all analyzing the situation to correct it in the most appropriate way.
Do you want to know the cost of waterproofing your existing terrace? Would you like to carry out a rainproof treatment on your balcony without demolishing the floor? Do you want to know all the solutions for water infiltration?
Turning to Di.Vis, active between: Lombardy, Emilia Romagna, Veneto, Friuli Venezia Giulia, Trentino Alto Adige, Valle d’Aosta, Piedmont and Liguria, you can permanently eliminate water infiltration from balconies and terraces.
DAMAGES TO OUTDOOR PAVEMENTS
Statistical surveys tell us that more than 50% of the lawsuits in construction involve infiltration problems and more than 60% of these causes are due to problems in the waterproofing layer of coverage.
In order to repair the damage to an exterior pavement, some important criteria must be evaluated:
- The resistance to loads
- Frost resistance
Load and impact resistance is an inherent characteristic of both the coating material and the supporting structure. The manufacturers of the coatings are required to declare their use and ensure, through UNI EN or ISO certifications, the conformity of the declared characteristics with the materials sold.
Frost resistance must also be guaranteed by the manufacturer; this characteristic must be associated with other peculiarities: resistance to slipping (defined as anti-slip, essential for safety), mold and stains.
DAMAGE TO JOINTS
One of the most frequent areas of wear and tear is the “joint”: the interstice between the tiles that is filled with an adhesive and plastic material called plaster, capable of compensating for the natural deformation of ceramic materials caused by temperature changes.
However, the continuous expansion and contraction of the tiles can accelerate the degradation of the substrate, causing the formation of cracks in the glue that joins the tiles to the substrate; under the action of frost, the cracks increase in size, leading to the detachment of the tiles from the substrate.
This is the most critical moment since the direct exposure of the subfloor (screed) to atmospheric agents causes its rapid alteration; this is because it’s made of cement and causes the loss of its waterproofing power.
