Roof Waterproofing
Membrane Roofing
But if for any failure in the making for over the years had produced the appearance of damp patches on the inside of the house, or leaks we will have no choice but to think of an urgent waterproofing of the roof. The first question that arises is about the degree of difficulty in carrying out the work and the second relates to the cost and if offsets do yourself. If you read this article carefully you will realize that in many cases it will be possible for you to make a good waterproofing and always will be a substantial savings. Even in the case of hiring professionals, if you are aware, will have the advantage of knowledge.
Roofing Types
From waterproofing: Since ancient times, against the rain was a concern of man and to the extent of the progress of humanity were dropping some and taking other techniques. The first melted animal fat mixed into the mud of the roof and anticipating the future of the waterproofing. And not to mention the mineral oils that used oil in order that the water does not wash the precarious roof of the hut.
Currently, waterproofing methods have evolved in variety and quality according to scientific: colorless paints are pigmented fiber incorporated, others are derived from petroleum-based solvent and other water-based. Each is adapted to the solution of various causes of the leaks. When these paintings fall short because the amount of damage exceeds the curative possibilities of them, will be necessary to resort to more forceful methods: the membranes.
Roofing membranes
Corralones materials, PinturerÃas, specializing in waterproofing houses we offer a variety of asphalt membranes. The differences go by the marks, the thickness, the appearance and exterior finish, weight etc. The first thing we have to determine, before we in the pursuit of material, is whether the place where the membrane will be placed to bear or not transit. Many times we have a terrace where the trail of clothing or sometimes use it to put a reposeerá and fresh air and sun while we rest. Other times, the membrane will be placed on roofs of inaccessible and not used only as a cover, whether metal or concrete. The important thing is to know what is intended and from there it brings the cost.
What you should know is that a membrane mainly consists of asphalt, aluminum and polyethylene. The asphalt should be pure, free of charge as talc, limestone, etc. used to lengthen and give more volume to the time he loses elasticity. Aluminium, not always present. Usually is the visible face of the membrane and acts as a containment of the asphalt, while the light reflected by ensuring that the temperature falls a few degrees on summer days rigorous. Polyethylene is a plastic film in the case of good membranes is in two different positions. In all forms the lower face, which is attached to the ceiling. That movie is what makes possible the asphalt rolled without sticking to the other side, but also that melts on contact with the flame of the torch and enables adherence to the surface to which it is intended. The other position that is almost invisible amid the asphalt. This hidden layer of asphalt on the inside is called “soul.” It’s the lifeblood, and a guarantee of waterproofing and reinforcement is the dilation attenuates exaggerated by climate change and traction. And of course, those who resist in the case of compressions, shocks and punctures. If you make a clean break in a membrane is likely to see it with a magnifying glass. Otherwise it is necessary to heat a piece to a simmer, remove the aluminum and polypropylene base, melt the asphalt without burning and to the extent it from running, be it the central reinforcement: the soul. If not found, skip trying to forget about the membrane that is cheap. The other treatment is cold. To put a strip of membrane in the freezer and wait until it takes its temperature can be determined the degree of flexibility and fragility of it. The membrane more flexible, take longer to jump like a broken glass and is likely to leave bare the soul, as it to be of good quality does not fracture, ie, asphalt, low temperature crystallization, but the polyethylene no.
