What does it consist of?

On many occasions it has been said that the roof is the fifth façade of a building, since leaving aside that both are part of the enclosure of a building they have little else in common.

Historically, the functional requirements of roofs have been to waterproof, give stability and beauty, but at present when building a roof it is also necessary to face the problems of vapor passage, thermal and acoustic insulation, durability and especially the economy.

This increase in demands has meant that many roofs have lost their inclination, which can facilitate the appearance of humidity inside the building due to the accumulation and retention of rainwater.

That is why it is very important to choose a good roof waterproofing system that is capable of avoiding this water seepage problem.

Why are the covers damaged and no longer waterproof?

The main reason is the dimensional changes of thermal origin and the aging that the waterproofing sheets present due to inclement weather.

Throughout their useful life, the waterproofing sheets will be exposed to continuous sudden changes in temperature that will cause continuous expansion and contraction in them that end up leading to breaks that will allow the passage of water.

DO YOU WANT TO WATERPROOF A DECK OR TERRACE

We can help you

How can it be solved?

To ensure the tightness of the roof we have to use waterproofing materials that create a flexible, elastic film, resistant to cold and heat and solar radiation. They must be able to adapt to the dimensional changes of the roof without tearing.

Why DECOPROYEC sprayed cork?

DECOPROYEC sprayed cork is mainly composed of granulated natural cork which is waterproof by itself.

In its cavities, natural cork has hydrophobic organic substances that repel liquid water.

In addition, the vehicle in charge of distributing the granulated cork evenly on the roof is a waterproofing base that gives our material a high modulus of elasticity so that it is capable of absorbing the expansions caused by inclement weather.

This resin in turn is protected by the cork granules that act as a protective blanket, which ensures durability superior to that of any other type of waterproofing sheets.

Only in the case of roofs with little or no inclination should our DECOIMPER membrane be applied previously to the sprayed cork to achieve a perfect waterproofing.
