Coating solutions obsolete

asphalt

Traditional solutions for surface coatings, called preforms, such as asphalt or butyl, are almost obsolete.

At present, the asphalt membranes and fabrics butyl, butyl rubber, among others, there is little that can cope with the continuous solutions such as liquid membranes: Polyurea.

Disadvantages of asphalt membranes.

i) Low quality.

The main disadvantages of fabrics or asphalt membranes are their relative quality, as should come from a strict and technical control. For example, they may be made ​​from recycled, non-polymeric, with low elasticity of asphalts.

Also, bands or strips of one meter wide should be welded together in situ, where they are placed; it which can lead to have leaks, for example, in the case of leaky roofs.

ii) Labour unskilled labor.

On the other hand, the major disadvantage in waterproofing membrane or bituminous membranes is labor and adequacy of operator, who requires expertise in the application of this material.

This, added to the quality of asphalt or surface where membrane is put .

Rubber Fabrics.

Similarly, rubber fabric, also called "butyl", are very elastic and waterproof but fail in those places where they are glued or adhered together with the other strip.

The only ones that can offer some security are those that come factory assembled and come to work in one piece.

Best solution: Poliurea.

Poliurea CODELCO

Instead, the liquid membrane of polyurethane or polyurea is extremely resistant to the effects of chemicals and water:

  • The sealing surface is perfect, avoiding any kind of filtration.
  • Major resistance to corrosion and abrasion, major durability and ductility than the traditional solutions.
  • Easy maintenance and excellent aesthetics.
  • It is an elastic, continuous and seamless membrane.
  • It is a bonded coating.
  • Adaptable to most irregular surfaces.
  • Applicable on almost any substrate.
  • Fast curing, allow for almost immediate use.
  • It can to coat and to repair without the need for masonry.
