Rain, winter, and ice are often symptoms of upper infiltration risk that, if not solved, can cause damage to the building structure over time. Usually, these sorts of issues arise from poorly or worn installed waterproofing. Let’s examine a few solutions used to resolve or avoid these issues on terrace and balcony floors.
• Choose the foremost suitable waterproofing solution for renovations: Based on the conditions of the balcony or terrace, you’ll opt for the best solution by calculating several factors. If the flooring is in perfect shape, it’d be enough to waterproof the floor covering directly. However, if there are problems with the tile, like holes or cracks, it’s would be good to get rid of them and do the under deck waterproofing membrane, that is, the substrate.
• Waterproofing solutions without removing the tile: If the flooring is in proper condition, without tenting or cracks, an under deck waterproofing membrane may be a good solution to employ without having to detach the tiled surface. It’s very easy to use and can be applied fast with brushes or rollers onto the entire surface without leaving gaps while producing a thickness of only a few millimetres.
• Waterproofing solutions between tile and substrate: If the flooring is unsuitable or damaged, it’s necessary to remove it completely and intervene in the layer underneath i.e. on top of the substrate. Two major solutions stand out from what’s available on the market: under deck waterproofing membrane or waterproofing liquids.
• Rolled membrane waterproofing systems: On the market, there are numerous solutions during which to use rolled membranes to waterproof the substrate. The foremost commonly used are bituminous, self-adhesive waterproofing membranes which will be applied with hot air welding on site.
• Bituminous membrane waterproofing system: Bituminous membranes are the foremost used system to waterproof under the substrate of balconies and terraces. These under deck waterproofing membranes are derived from the distillation of petroleum. In pedestrian areas, the application of a bituminous membrane with a thickness of 4-5 mm is recommended, to aggravate mechanical resistance and maintain the elongation property that’s characteristic of this material.
• Cement-based liquid compound waterproofing system: an alternative to a bituminous membrane is the application of a cement-based liquid layer that is simple to apply on top of the substrate. The merchandise is a cement-based mixture to which polymers impervious to water are added. The tiles are often then applied over this layer with the appropriate adhesive tile. This procedure is simpler than the previous one, but the cement layer isn’t perfectly waterproof and could easily dilate as a result of temperature changes, allowing a small amount of humidity to undergo the layer underneath.
• Waterproofing solutions under the substrate: the simplest solution to solve and prevent any type of degradation or subsequent infiltration is to intervene under the substrate. For optimal results, the procedure should include the appliance of an under deck waterproofing membrane, on top of which is applied a drainage membrane that gives safety.
