Waterproofing membrane system and method

#This patent application relates generally to a waterproofing membrane system and method, and more specifically, to systems and methods for waterproofing a concrete substrate and other related waterproofing applications.

#Laminate sheets are typically used for waterproofing concrete. These laminate sheets, however, are normally applied to a concrete substrate that has already been formed, such as a building foundation. As a result, such laminate sheets are applied on a cured concrete surface. In other concrete applications, laminate sheets can also be applied to concrete that is freshly-poured, or on surfaces that are not yet cured.

#Conventional laminate sheets offer limited waterproofing capabilities when applied to either cured or non-cured concrete substrates. The integrity of a waterproofing membrane system is generally based on materials, size, dimensions, and arrangement of various layers. In many cases, conventional laminate sheets do not form an adequate water barrier or are cumbersome to use and install, which also results in poor waterproofing. In addition, conventional laminate sheets lack durability in extreme weather conditions and typically cannot accommodate heavy foot traffic or other physical wear.

#Features of the present disclosure are illustrated by way of example and not limited in the following Figure(s), in which like numerals indicate like elements, in which:

#FIG. 1 illustrates a cross-section of a waterproofing membrane system, according to an example;

#FIG. 2 illustrates a cross-section of a waterproofing membrane system, according to another example; and

#For simplicity and illustrative purposes, the present disclosure is described by referring mainly to examples and embodiments thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be readily apparent, however, that the present disclosure may be practiced without limitation to these specific details. In other instances, some methods and structures readily understood by one of ordinary skill in the art have not been described in detail so as not to unnecessarily obscure the present disclosure. As used herein, the terms “a” and “an” are intended to denote at least one of a particular element, the term “includes” means includes but not limited to, the term “including” means including but not limited to, and the term “based on” means based at least in part on.

#As described above, conventional laminate sheets offer limited waterproofing capabilities when applied to either cured or non-cured concrete substrates. They lack durability and cannot accommodate heavy physical wear or extreme conditions. Use and installation of conventional laminate sheets are also cumbersome. In many cases, conventional laminate sheets do not provide an adequate water barrier for which they are created.

#FIG. 1 illustrates a cross-section of a waterproofing membrane system 100, according to an example. As shown, the waterproofing system 100 may include various layers. For example, the waterproofing membrane system 100 may have a first layer 102, a second layer 104, a third layer 106, and a fourth layer 108.
