Bentonite Waterproofing

Use this CSI 3 part SimpleSpecs™ master specification to specify bentonite waterproofing geosynthetic sheet, panelized, or composite sheet form, for use as below-grade, underslab, and split slab construction.

 

Waterproofing incorporates bentonite clay which absorbs water until it is fully saturated, at which point no water will pass through.the clay. Composite bentonite waterproofing incorporates both bentonite clay and a prefabricated waterproof sheet.

 

In geotextile sheet form bentonite waterproofing consists of bentonite clay between two geotextile fabrics. Since it conforms to irregular surfaces it is useful for waterproofing against excavations and lagging but is also used for traditional below-grade and underslab applications.

 

Waterproofing in panel form places the bentonite inside corrugated cardboard panels that are mechanically fastened to vertical surfaces or placed loose over a mud slab or prepared subgrade in underslab applications.

 

Composite bentonite waterproofing combines bentonite clay that is factory applied to an HPDE waterproofing sheet.

 

Since bentonite swells when it becomes wet it can exert tremendous pressure on overlying slabs and adjacent construction. Consult with a manufacturer when considering waterproofing for these applications.

 

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.

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.
