Here is an overview of the different types of waterproofing for roofs remembering that there is no suitable product for every circumstance but the best type of waterproofing depends on the situation and can only are assessed by a competent National Restoration Experts technician. The bituminous membranes derive from the distillation of oil. Generally they are prefabricated and often provided with armor. They usually need surface protection given by the floor or gravel which is built above and have good mechanical strength.

Prefabricated polymer membranes

A polymeric synthetic membrane is an impermeable. Generally prefabricated membrane in which there is no bitumen or it is in a percentage lower than 50%. They are marketed in rolled sheets and are divided according to their composition or based on the main polymer they are made of PVC or polyethylene. Hey providea good elasticity that allows the membrane to absorb strong temperature variations and to withstand the small movements and settlements that may occur between the support and the floor.

Self-adhesive membranes

The adhesive membranes are glued to the laying surface by simple pressure at room temperature without the need for flame. As a consequence it is a cold system in which the installation takes place with similar methods and precautions typical of the type.

Self-protected and slated membranes

The self-protected membranes are those in which it is possible that the waterproof layer is left exposed to atmospheric agents. To withstand bad weather and UV rays they consist of a surface covering able to protect the membrane. The protective layer can be slated or with copper or aluminum sheets. Those coated in copper or aluminum is more expensive but is not subject to wear and tear.

Liquid waterproofing

Unlike prefabricated membranes liquid waterproofing allows greater versatility as the application allows acting on the entire surface without the possibility of leaving uncovered points. They are highly resistant to stagnation of water, UV rays, bad weather and cycles of freezing and thawing. If the existing flooring is intact and well anchored to the substrate it will be possible to waterproof the balconies and terraces even if already tiled without removing the old flooring.

Conclusion: Cement-based waterproofing products

They are a particular type of protective waterproofing formulated in the form of mortar with elastomeric compounds that allow the preparation to deform with the product without detaching. These cement based waterproofing products are used for concrete surfaces for the waterproof elastic shaving of micro cracked plasters.There are waterproofing systems that also act as thermal insulation thanks to the excellent resistance to air and water. They are usually flat and pre stressed insulating panels coupled with polymer bitumen membranes ideal for the insulation of roofs, attics, vertical walls and untamable floors.
