Project Information
WADIT® was factory installed in PZC-18 steel sheet piling before pairing at the mill site in Petersburg, VA. The sealed and paired PZC was then shipped by rail to California where they were used to construct a circular cofferdam in a riverbed. No extra handling or care is needed when using WADIT®, you ship, store and install sheet pile without restrictions or extra steps.
The project required an exceptionally watertight structure to meet strict environmental and engineering requirements. After comprehensive evaluation, WADIT® was selected as the most effective steel sheet piling sealant on the market for this critical application. The pre-applied sealant ensured efficient on-site installation while guaranteeing the watertight integrity essential for protecting the sensitive riverbed ecosystem.

Interesting Facts
Factory installed sheet pile enabled efficient installation of a watertight circular cofferdam in a riverbed.
The Challenge
Build a watertight cofferdam in a riverbed under strict environmental and engineering conditions.
For Contractors
The use of WADIT®-sealed PZC-18 sheet piles significantly reduced on-site preparation time and minimized risk of construction delays. Pre-installation at the steel mill in Petersburg, VA streamlined logistics and ensured consistently high sealing quality. The prefabricated piles were transported by rail and efficiently installed on-site, demonstrating the advantages of factory-controlled application.
For Engineers
The circular design and exceptionally watertight requirement demanded high-performing interlock sealing solutions. WADIT® provided reliable performance in water-exposed and water-saturated conditions, meeting stringent specifications for hydraulic integrity. The circular geometry of the cofferdam required precise alignment and joining of interlocks, which was facilitated by the pre-applied sealant system.
For Owners
The solution delivered a robust, cost-effective, and environmentally secure cofferdam structure with minimal risk of leakage or construction delay. The project met high-performance standards for watertightness, protecting the surrounding riverbed ecosystem while maintaining schedule adherence and budget control. The pre-sealed system provided additional assurance of quality and reduced uncertainty in critical water-retention applications.
Factory Installed WADIT®
The factory installation of WADIT® sealant at the steel mill in Petersburg, VA provided several key advantages:
- Consistent application quality in controlled conditions
- Reduced on-site installation time
- Guaranteed seal integrity before shipping
- Cost-effective solution for achieving watertight performance
This innovative approach to pre-sealing sheet piles demonstrates the effectiveness of planning and preparation in complex cofferdam construction projects.
