About This Project

Denver Rapid Transit District (RTD) has utilized the Bridge Preservation™ spray applied waterproofing membrane systems throughout the years for their light rail bridge decks. At the Denver Union Station, Bridge Preservation™ Bridge Deck Membrane (BDM) spray applied waterproofing membrane was installed, followed by the application of Bridge Preservation™ Integrated Ballast Mat, a seamless, spray applied ballast mat protection system.

The spray applied ballast mat (Integrated Ballast Mat™) utilizes a proprietary filler combined with Bridge Preservation™ spray applied waterproofing membrane to create an extremely durable waterproofing and ballast protection system. Starting at a minimum thickness of 250 mils, the Integrated Ballast Mat™ can be applied at various thickness on flat decks to create slope for water drainage.

Advantages:

• Completely seamless spray applied ballast mat protection system
• Chemically bonds to spray applied waterproofing membrane base coat
• Provides increased dielectric properties
• Provides additional waterproofing protection
• Can be applied at various thickness to create slope on flat decks
• Cost effective, similar to cost of conventional ballast protection board
• Made in America
