Cold Fluid-Applied Waterproofing

Use this CSI 3 part SimpleSpecs™ master specification to specify cold fluid-applied waterproofing for use on below-grade walls and decks where it will be covered by soil or other construction.

 

Waterproofing is a moisture-curing urethane that is applied by roller, spray, or squeegee to concrete, masonry, or plywood substrates. This type of waterproofing cannot be left exposed to weather.

 

Since it is applied in fluid form this type of waterproofing forms a continuous, seamless barrier against water penetration.

 

This waterproofing requires a protection course to prevent damage during backfilling and placement of overlying construction. A drainage course applied over the waterproofing reduces hydrostatic pressure, thereby reducing the possibility of leaks. Some drainage boards can also act as the protection course.

 

Some widely used cold fluid-applied waterproofing materials are prone to failure involving water absorption. These products meet the standards of ASTM Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course (C 836). Experienced investigators of waterproofing systems are familiar with this failure mode; some refer to the convoluted appearance of a membrane after water absorption as “braining.”

 

Our investigation into this mode of failure examines the properties of waterproofing materials and application methods. This report includes the results of testing with four different application methods, and varying conditioning periods. Testing included immersion in water at 50 °C (122 °F).

 

Test specimens absorbed more water than allowed by the Canadian General Standards Board’s (CGSB) standard Membrane, Elastomeric, Cold-Applied Liquid, for Non-Exposed Use in Roofing and Waterproofing (CAN/CGSB-37-58).

The SimpleSpecs™ master specs concept
 
Adding More Words Does Not Make Specifications More Enforceable.    
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
 
Specifications have grown evermore wordy over the years for several reasons:
  1. The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable.  In fact, quite the opposite is true.  Having shorter, easily understood specifications makes us less likely to have problems in the field.
  2. A belief that having lots of words protects us from a Contactor making mistakes.  There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
  3. Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
 
Easier to Edit

SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.

Non-Proprietary

Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.

 
Hidden Guide Text

Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.

 
Streamlined Editing

SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually.  Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
