Use this CSI 3-part SimpleSpecs™ to specify EPDM and polypropylene pond liners.


A pond liner is a waterproof membrane that is used to line the bottom and sides of a pond to prevent water from seeping into the surrounding soil. They are typically made of rubber, PVC, or HDPE (high-density polyethylene).


Pond liners are important because they help maintain the pond’s structural integrity and prevent water loss due to leaks or seepage.


They also help to control the water quality by keeping soil and other contaminants out of the pond.


Additionally, pond liners make cleaning and maintaining the pond easier and provide a barrier to protect the pond from animals or other potential hazards.


The lifespan of a pond liner depends on the quality of the liner, the conditions it is exposed to, and the level of maintenance it receives.


Generally, a well-maintained pond liner made of high-quality materials can last for several decades.


However, it’s important to regularly inspect the liner for signs of wear and tear, such as cracking or holes, and to repair or replace it as needed.

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.


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.
