For nearly thirty years, advanced polyurea technology has been employed as a protective coating and waterproofing membrane for diverse engineering and construction applications, including bridge deck waterproofing. Polyurea coatings have proven to be one of the most resilient, durable, long-lasting, impermeable, and dependable waterproofing membranes in the industry. 

Structures that lack the protection of polyurea coatings, or have traditional protective coatings in place, are more likely to show signs of premature decay, rust, corrosion, and other damages due to prolonged water exposure. 

To maintain the structural integrity and safety of bridge decks, it’s important to apply a coating such as a polyurea that can withstand anything and everything Mother Nature can muster.

Here’s what you need to know about bridge deck waterproofing. 


Why Is Bridge Deck Waterproofing Important?

Bridges withstand heavy traffic, which often causes the concrete deck to develop tiny cracks. Cracks are bad news for any concrete structure because they allow water to seep into the deck and corrode the reinforcing steel. This corrosion and deterioration can weaken the bridge’s structural integrity, increasing the potential for partial or total collapse. 

In addition, the steel supports that hold the bridge structure in place are also prone to rust and corrosion caused by environmental factors such as weather conditions, road salt, and steady usage if they’re not appropriately protected. That’s why keeping excess snow, ice, salts and water away from bridge decks is extremely important to protect the bridge and extend its lifespan.

The best way to protect bridge decks from premature deterioration is by waterproofing it. Bridge deck waterproofing is the process of applying a protective, waterproof coating to the bridge deck to protect it from environmental and structural damages, such as corrosion and rust.  

Bridge deck waterproofing can be applied during the bridge construction phase or many years later as a restoration program.

Not only does bridge deck waterproofing extend the lifespan of decks, but it can also save money, reducing the need for expensive maintenance and rehabilitation. 

Multiple systems have been used to protect bridge decks from corrosion and damages; however, these other systems often fail over time. Properly applied bridge deck waterproofing using a polyurea coating, on the other hand, ensures the bridge is safely waterproofed for many years and significantly extends the lifespan of the bridge compared to other waterproofing processes. 



What Are the Advantages of Using Polyurea in Bridge Deck Waterproofing?

In addition to the extremely easy application and fast curing times, there are many reasons why polyurea coatings are the ideal solution for bridge deck waterproofing: 

  • 100% solids with no solvents or VOCs, making it environmentally friendly
  • Abrasion resistance
  • Chemical resistance
  • Excellent elongation and tensile strength
  • Great crack-bridging ability 
  • Unaffected by humidity during the application process
  • Excellent adhesion and coating performance for countless substrates
  • Thermal stability to a wide range of temperature variations 
  • Once fully cured, the finished product is a smooth, seamless, and strong membrane
  • Thickness level can be selected and adjusted during application
  • It can be applied to vertical and curved substrates to almost any desired thickness level without any sagging
