1. History of the tiles
In the construction industry there is a concept of work that is inevitable and that 100%
of new construction should be used, the waterproofing material especially in the
Mexican republic is in great demand due to the geographic location of our country and
the rainy season which usually lasts 6-8 months each year.
For builders, the decision to apply some kind of waterproofing varies depending on the
surface, cost, durability, and warranty application, it makes this very often leads them
to make a decision if it is not inaccurate information properly before taking the
decision.
Formerly the way to waterproof the roofs of the buildings did not include any material
industrialized and had to use natural material taken from the place.
The roofs of the old farms, churches, convents, houses, etc., Used the housetops
system consisting of a mezzanine consists of wooden beams, clay tile handmade type
quadroon and a layer of clean soil compacted achieved a cant approximately 40-80
inches depending on the area of each ceiling finally applied a layer of red brick
annealing handmade petatillo shaped and finally apply a solution of alum which
achieved an impermeable surface.
Note that this type of roofs lacked rain downspouts and drainage could usually based
on gargoyles located on the perimeter of the roof and usually emptied the water
quickly to prevent puddling.
Importantly, this protection system for roofs was used for many years, over 300 to be
precise and only thanks to the industrial revolution and the discovery of oil begin to
invent materials made from oil and ranging to revolutionize the market.
With the advent of the oil industry in the 20's and the discovery of new materials such
as oil refining petrolizados, refined gasoline, diesel and refined oils of different
densities, using a mixture of crude oil and ammonia known as tar, which began to be
used as a protective coating on new concrete roof due to the smooth surface and the
possibility of generating a rubber layer which when cooled becomes a flexible rubber.
For a long time the tar was used directly in both foundations to roofs as it appears on
the market the cardboard sheet asphalt, that is a very thick cardboard sheet with tar
that washed into the role of a protective and waterproof membrane before of traditional
brickwork.

2. But eventually the builders discovered that after a certain time sheet deteriorates,
which caused him to get up the brickwork every time it appeared a leak or moisture
thereby causing the repair to become a true work of construction on the roof of the
building.
In the sixties and through research conducted by the NASA in the space race trying to
bring man to the moon, they discover a myriad of new materials that will force the
transformation of the plastics industry, thereby achieving the discovery glass fiber,
recycled material which enables applications in various fields and particularly in the
area of the waterproofing, obtaining a mesh or fabric of very thin glass fiber and of
small thickness, that being the principle achieve the prefabricated waterproofing
membrane , as best call, membrane fiberglass reinforcement.
This waterproofing system achieves a success in the seventies and eighties virtually
eliminated the use of the famous tar and asphalt board, however, and due to the
growth of cities, pollution and acid rain, it is found that the membrane system
reinforcing mesh weathers very quickly forcing the customer to renew this membrane
on average every three years, which cost in question fails to repay the investment,
plus the usual inconvenience of having to remove the old material.
The petrochemical industry continues to investigate new materials and prefabricated
membranes achieved by modifying obtain crude oil and adding glass fibers and
polyester layers of materials applied accomplishing heat vulcanizing plates allow
achieving a perfectly sealed and obtaining a greater resistance to rain acidic
weathering of materials and thickness more important, giving you greater elongation
temperature changes in the material.
In the last decade, the development and research of new materials is enabling significant
progress achieved so there is now a rubber backing membrane that achieves greater
resistance to acid rain and increased elongation sudden temperature changes achieving
smooth and uniform coating but for now has not had the required disclosure and that once
mention.
