If your steel sheet pile project involves cofferdams, dewatering, tunnels, cutoff walls for site remediation, or any application where water leakage presents a challenge then iSheetPile has the solution.

As a licensed dealer of WADIT®, a globally proven sheet piling interlock sealant, iSheetPile can meet all of your waterproofing needs.

WADIT® can be used with all types of hot rolled and cold formed sheet piling interlocks in every environment (tropical to arctic) possible and particularly in marine conditions.

Tests have demonstrated that leakage through sheet pile walls is reduced up to 95% when interlock sealants are used; and sealed joint sheet pile cutoff walls are anywhere from 100 to 10,000 times more effective as groundwater flow barriers (sealed walls typically exhibit hydraulic conductivity in the 10⁷ to 10¹⁰ cm/sec range) than unsealed interlock walls. Furthermore, tests conducted in Germany have shown WADIT® easily withstanding even 5 bars of water pressure and maintaining its ability to resist water seepage.

Additionally, iSheetPile can supply your project with Adeka P-201 steel sheet piling sealant that is comprised of a mono-component material made from urethane pre-polymers.

For further information on the Adeka water sealant system for steel sheet piling, please see their video.

Adeka sealant is available through iSheetPile but has three major disadvantages compared with WADIT® interlock sealant:

1. Once Adeka is in contact with the water table, the filled sheet pile should be driven to grade within 2 hours to avoid expansion of the sealant. With WADIT®, there is no time limit to driving.
2. It is recommended to apply Adeka under shelter at ambient temperatures while WADIT® has a much wider temperature range and has been applied outdoors for systems ranging from tropical to arctic conditions.
3. Average productivity of applying Adeka is approximately 200 meters per 8 hours shift — about 650 feet. During a similar shift, WADIT® can be applied at roughly 10 times the speed and amount therefore saving enormous time on labor and construction costs.
