Terrace: Before and After Coating

  • In order to waterproof a balcony or a terrace, first of all it’s necessary to evaluate the existing conditions of the area to be treated because, depending on the state of conservation of the balcony or terrace on which you want to intervene, there are different solutions and different steps to follow, more or less invasive to restore or to do a new waterproofing system.
  • The first thing to evaluate is the state of the existing flooring, that is the visible layer, which is also the easiest to investigate regarding its state of conservation. This evaluation can be carried out, for example, by checking if the volumes of the joints are consistent or missing, because in most cases it’s from the joints that the water starts to infiltrate and therefore the waterproofing effect of the finish is missing.
  • Consequently, the water will begin to deteriorate the whole pack, with serious damage to the elements. In parallel, it’s possible to check the status of the elements of the flooring, in fact, even if these are for outdoor and therefore waterproofing, any cracks or breakages of the same provide access to water creating infiltration points.

Steps to waterproof a balcony or a terrace

First of all, it’s necessary to distinguish whether it’s necessary to carry out waterproofing again or if we are talking about the restoration of an already existing waterproofing system of a balcony or terrace. This evaluation allows us to understand at what level of the waterproofing package we need to intervene.

With regard to the treatment of details such as wall-floor corners, expansion joints or drains, special preformed elements are usually created to be used with the various waterproofing systems proposed, and may be butyl tapes, gauze or strips that provide additional waterproofing in those points where the risk of leaks is always greater due to their particular complexity of geometric conformation.
