Terraces, balconies and flat roofs are external extensions of the living spaces which also have the task of covering and protecting the underlying volumes from water. In the presence of water infiltrations, they can be the cause of considerable inconvenience, linked to the work necessary to recover this functionality and the associated costs.

When the waterproofing function fails, the repairing technique must be chosen carefully, making a series of appropriate preliminary assessments that involve considerations: technical, economic and aesthetic.

A precise collection of preliminary information is the basis for a correct assessment of the causes and extent of the deterioration. In the first place, it is essential to have perfect knowledge of the construction technique used in the construction of the flat roof since, depending on whether it is a brick-cement slab, a pre-slab, a solid slab in reinforced concrete or another type of structure, different could be the critical points on which to focus attention. A preventive analysis of the structure also allows the identification of surfaces potentially involved in condensation processes, therefore being fundamental in orienting any diagnostic investigations.

In more complex cases, an accurate overview with photographic details is a basic starting point, better if accompanied by thermal images that can highlight the extent of infiltrations. However, some weaknesses are frequently present and it is worth remembering:

  • water collection points and passing bodies;
  • joints between horizontal surfaces and walls;
  • technical joints and contraction joints;
  • contact lines between materials with different thermal coefficient.

Particular attention should be paid to all these weaknesses, as they could be decisive in the deterioration in progress and in the choice of waterproofing technique.

Three waterproofing techniques are considered below which, thanks to their different performances and purposes, embrace the vast majority of cases. The techniques are:

They are very different techniques from each other, each of these characterized by precise advantages and equally precise limits. The choice of one of these three solutions must be taken considering technical, economic and aesthetic aspects summarized in the following table.

Products and technologies to use

PROTECH BALCONY SYSTEM, composed by: acid detergent for deep cleaning, putty, polyurethane sealant and transparent non-film impregnating treatment.

OSMOCEM FLEX SYSTEM, composed by: elastic band for connections and joints, alkali-resistant glass fiber mesh embedded in a two-component elastic/plastic cementitious compound.

SYNTECH POLIUREA SYSTEM, composed by: epoxy primers for concrete and steel surfaces, various types of polyurea resins and final protective polyurethane treatments.

 

 

PROTECH BALCONY

Solution based on special silane and siloxane resins in solvent, highly penetrating, transparent (colourless), for quickly, effectively and economically waterproofing balconies, tiled terraces, concrete roofings, external stairs, etc., without removing or intervening on the existing flooring. It does not change the appearance of the support on which it is applied and it does not alter the original slipperiness or its water vapour breathability. It is quick to apply and does not require skilled labour or professional equipment. The flooring treated will be usable after only 2 hours of laying.
