An excellent waterproofing of terraces and roofs is essential to prevent rainwater from infiltrating the house on a structural level. If the water gets under the plaster it can cause visible damage right away: halos, bulging and detachment of plaster are only the first signs of infiltration related problems which, if neglected, can cause significant damage and require costly repairs.
FAQ: Frequent Questions
Can one check if the waterproofing layer has lost its efficiency and functionality? You can find a quick solution by contacting EdiliziAcrobatica®. Without using scaffolding or aerial platforms, but only a double mountaineering-type safety rope system, our workers can work on terraces, balconies, roofs, and eaves to rebuild an effective barrier against the passage of humidity, using tried and tested procedures and products of the best quality.
Before starting any intervention, our technicians will carry out an inspection that will help to understand what is the cause of the signs of damage on the surfaces. Often the origin of the problems is to be found in the wear of the waterproofing membrane or of the existing flooring. An accurate inspection is necessary when it is not possible to clearly identify the cause of the problem, the infiltrations, in fact, are also produced in these situations:
- check to find any errors made during the installation phase of the thermal insulation
- check the slope of the screed
- check for water leaks from the systems.
Only with a professional evaluation will it be possible to locate the points of water penetration, understand the causes of infiltration and define the most suitable intervention, which may be:
- a waterproofing overlapping the existing floor
- a waterproofing following the removal of the flooring
- a demolition with consequent total restoration, in case the screed is not in good condition.
There are many methods of waterproofing terraces and roofs, from the traditional system with bituminous membrane sheets to the liquid membrane, from two-component elastic cementitious mortar to the most innovative synthetic polymeric membranes. The methodologies that we mostly carry out in EdiliziAcrobatica® with the rope-access technique are: waterproofing with bituminous sheath and those with synthetic HDPE membrane.
Waterproofing with bituminous sheath
The most traditional method used in waterproofing terraces, roofs, cornices, sloping surfaces, canopies and attics is the one that uses the bituminous membrane. ; It is a product derived from the distillation of petroleum, which comes in rolls (usually fixed by heat using a torch or with glue or self-adhesive) or else it is found in a gelatinous state. Bituminous membranes are widely used, because they have good mechanical resistance, and are long-lasting and easy to apply. Moreover, thanks to the integral overlap, it is possible to renew an old covering by gluing a new membrane to it, thus ensuring a simple and quick maintenance in time.
Waterproofing with hdpe membrane
An effective barrier against the passage of humidity comes from the synthetic polymeric membranes that differ according to the chemical characteristics of the materials, including the synthetic membranes in high density polyethylene, often abbreviated as HDPE used by EdiliziAcrobatica®.
The reason why we have chosen them is simple: they are among the most innovative waterproofing products, offer a long life, excellent performance over time, allow the diffusion of vapor and are tear resistant. HDPE membranes, being an ideal barrier for both wind and water, are often used in the concrete topping and on the thermal insulation layer of the roof.
EdiliziAcrobatica® workers carry out waterproofing work on terraces and roofs with the construction method on ropes without the need to mount expensive scaffolding. Following the inspection, the most suitable type of intervention will be identified for your specific case and the operators will carry out the preparation of the surface which will make the work more effective and lasting.
The first step is to remove the damaged parts and, in the event that the screed is in poor condition, it may be necessary to demolish it together with the flooring. It is very important to check the condition of all the elements that can affect the water seal layer, such as cracks, railings attachments, fittings and joints. ; The next step concerns the installation, which is meticulously performed by our workers thanks to the use of the rope-access technique. This technique, which characterizes EdiliziAcrobatica®, allows us to complete the work in a short time, without causing inconvenience to the residents, because you will not have to install annoying scaffolding or aerial platforms for lifting personnel. The advantages given by the rope-access way of working affect the costs, which are considerably lower than those proposed in estimates in which the use of scaffolding or aerial platforms is considered.
Our estimates and inspections are always free of charge and are essential for us to understand the status of the parties involved and plan the useful intervention to solve the problem.
