INTERLOCKS & CLUTCH SEALANT
Sheet pile interlock sealant is designed to reduce or eliminate water migration through the interlocks of steel sheet pile walls. When properly applied, interlock sealants help create highly water-resistant retaining structures suitable for cofferdams, marine construction projects, cut-off walls, flood protection systems, environmental containment structures, and groundwater control applications.
ESC DPS-500 is a high-performance hydrophilic polyurethane sealant designed specifically for steel sheet pile interlocks. When exposed to water, it expands to fill voids within the interlock, improving wall water tightness and reducing seepage. Suitable for hot rolled, cold rolled, and cold formed sheet piles, DPS-500 is widely used in freshwater and seawater environments for cofferdams, marine structures, flood protection systems, cut-off walls, and groundwater control projects.
Its one-component formulation allows for easy handling and application, while its lightweight properties and excellent adhesion make it suitable for both open and confined working conditions. DPS-500 performs reliably across a wide range of climates and maintains its effectiveness through repeated expansion cycles. Upon immersion, it expands to approximately 200% of its original volume within 24 hours and exceeds 300% within 48 to 72 hours, enhancing the sealing performance of sheet pile interlocks.

INSTALLATION GUIDE

Achieving a water-tight sheet pile wall can be challenging due to site conditions, installation variables, interlock tolerances, sealant application methods, and the elevated temperatures that may occur during pile driving. These factors can influence the effectiveness of the sealing system and the overall hydraulic performance of the wall.
Drawing on decades of sheet piling experience, ESC has developed proven solutions to help improve sheet pile wall water tightness in a wide range of project conditions. Whether utilizing standard sealing systems or customized project-specific approaches, our team can support contractors and engineers in selecting the most appropriate solution for their application.
To assist with proper installation and performance, ESC provides a comprehensive guide covering interlock sealant application procedures, installation recommendations, and industry best practices for achieving water-tight sheet pile interlocks in cofferdam, marine, flood protection, and groundwater control projects.
