Hot & Cold Liquid Applied Roof & Waterproofing Systems

Plaza Deck Waterproofing

With the increase of moisture issues in modern building and construction, understanding proper waterproofing and drainage for the buried application is vital for ensuring a building free of water, moister and mold.

This presentation will focus on the overview of various waterproofing, protection course, and drainage methods that meet the standards of today’s plaza deck applications. Additionally, we will review a variety of overburden systems that have been mandated for moder plaza deck waterproof systems.

Learning Objectives:

1. Overview of substrate evaluation by looking at the proper PSI and moisture content of concrete to apply adhered membrane waterproofing and review acceptable products for green concrete.
2. Compare the difference between adhered membrane technologies and non-adhered technologies in horizontal waterproofing applications.
3. Review various options for protection course, insulation, and drainage layers with various overburden such as poured concrete, pavers, growing medium and/or asphalt.
4. Establish transition detail to various substrates, different waterproofing technologies, change of plans and various drain tie-ins.

Green Roofs

The U.S. population is forecast to increase by 50% over the next 50 years, yet cities are already struggling to cope with growth and economic development,

• Open spaces and undisturbed land have given way to buildings and roads.
• Sealed with concrete and asphalt, these surfaces no longer allow water to infiltrate the ground.
• Dark rooftops and pavement absorb and store energy for the sun during the day and reflect it at night.

The results are increased storm water runoff, increased urban temperatures known as the “urban heat island effect”, altered weather patterns, and the loss of greenery in the metropolitan areas. Green roofs can provide a solution to these problems.

Learning Objectives:

1. Establish different technologies and waterproof membrane products that can be utilized under the growing vegetation.
2. Establish methods for storing storm water and detailing how to remove excess water through drainage layer under growing medium.
3. Review root barrier needs based on the growing medium of intensive and extensive systems.
4. Establish best practices for waterproofing inside and outside corners, along with the vertical to horizontal transition details.
