Waterproofing Design

The importance of waterproofing terraces INSURANCE - MAINTENANCE Accurate maintenance plays a fundamental role in preventing damage from infiltration of design engineers consider the possibility of insuring waterproofing on terraces interesting of the balconies More than have signs of rust and exposed irons At least of homes in have traces of external moisture More than of homes in Italy have cornices and parapets with the cornice at risk of collapsing The presence of a habitable terrace can increase the price of a property up to of flat roofs and terraces are in detached or semi-detached houses...

of construction problems are related to terraces On average, a design engineer follows almost roofing projects in a year of the problems relating to terraces are caused by the absence of joints and therefore by incorrect design In Italy over of homes were built before 1981 of which is in poor conditions The perceived value of the importance of a habitable terrace has increased of which is in very bad conditions Ref. Volteco Research Centre data referred to italian market Waterproofing terraces and balconies

Closed balcony These balconies do not protrude and may even be retracted with respect to the profile of the building. They are generally closed on two sides. Open balcony Also called projecting balconies, they are the most common type of balcony. Their peculiarity is to protrude with respect to the facade of the building and are therefore usually open on three sides. Walk-out roof terrace It is a special type of roof terrace that only covers a part of the building. It has a dual function: roofing and outdoor projection of the flat from which one accesses. Roof terrace It is a terrace that covers...

Aspects of the refurbishiment The failure of terrace and flat roof waterproofing is one of the most widespread problems that often causes aesthetic and structural damages. Troublesome and harmful water infiltrations leaking from the terrace to the rooms below cause water and moisture stagnation, forming mould that is harmful, contributing to the deterioration of the structure. Keeping rainwater away is a crucial point to prevent its infiltration during its outflow towards the ground. It is therefore necessary to prepare surfaces with appropriate slopes in order to ensure the outflow of water...
