Unpacking Bulkhead Repair: A Deep Dive into the Use of Polyurethane Foams for Bulkhead Repair

Technical Podcast for the Infrastructure Repair Industry

Crafted specifically for marine and coastal environments, bulkheads are structures designed to strengthen soil conditions along the shores of beaches, lakes, and rivers. They not only maintain but also offer strategic protection to substrates from neighboring waters, ensuring the safety and longevity of adjacent structures. Beyond serving as mere protective barriers, bulkheads elevate the functionality of waterfront zones, ensuring a safe haven for both the buildings and the individuals who frequent the shoreline.

Join us for a captivating episode where we delve into the intricate world of bulkhead repair, focusing on the unique properties and application techniques of single and plural component polyurethane foams. Our guest, Jerald, a seasoned contractor with over three decades of experience, offers invaluable insights into the art and science of using these foams for long-lasting and efficient bulkhead restoration.

The Dual Role of Polyurethane Foams

Jerald sheds light on the distinct and synergistic functions of single and plural component foams in bulkhead repair, emphasizing their specific application techniques.

• Single-Component Foam: Ideal for water stop crack injections and substrate permeation grouting, single-component, accelerator adjusted, polyurethane foam sets the stage for comprehensive bulkhead leak sealing and soil stabilization. Master the technique of employing grout injection lances and needles to distribute the product effectively into the ground, anchoring sand and gravel — an essential measure for bulkhead stabilization and erosion prevention.
  
  
• Plural Component / Two Component Structural Void Fill and Lift Foam: Renowned for its efficiency in filling voids and stabilizing concrete structures embedded in substrate with voids and gaps, this foam can penetrate, fill, and strengthen unsupported areas effectively. In the hands of a skilled contractor, the product can be used to adjust and correct the alignment of structural elements under specific conditions. However, due to its potent expansion capabilities, it’s crucial to exercise caution. The intense outward pressure it generates could inadvertently shift structures beyond the intended position.
