If your sheet piling project involves cofferdams, dewatering, cutoff walls for site remediation, or any application where water leakage through the wall presents a problem, WADIT® is the solution.
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 10-7 to 10-10 cm/sec range) than unsealed interlock walls.
WADIT® is the smart choice sealant from a cost, safety and convenience standpoint.
Most common WADIT® applications include:
WADIT® has been tested to withstand 5 bars (~70 psi) of differential water pressure. This means it will remain in place and functional with even a 160′ head of water pressure against it.
Conventional materials become as hard as glass in temperatures of just 50°F. WADIT®, on the other hand, remains extremely flexible even in ground water (normally 41°F to 45°F throughout the year). This means that no sealant can break out of the interlock when the sheet pile walls are inserted, thus resulting in leaks.
WADIT® is non-toxic and is made from sustainable natural raw materials. WADIT® sealant can be used without any restrictions in sheet pile wall interlocks in ground and surface water areas … no fear of harmful effects if it is used in the area of drinking water extraction systems” (quote from the German equivalent of the Environmental Protection Agency (EPA)).
Once WADIT® is in the interlock, it doesn’t matter if it rains or snows: the performance of WADIT® will not be affected by weather. WADIT® can be transported and stored without restrictions. Furthermore, you can drive the piling as soon as 15 minutes after installing; or, let it sit in your yard or at the job site for months before driving.
WADIT® creates a secure bond even in extreme conditions, such as: strong water, ice or earth pressure, movements of the sheet pile wall, or displacement of the piles during transport, etc., in the interlock chamber. Even in daytime temperatures of 120°F, the material will remain stable in the interlock.
We stock WADIT® in the factories so your sheet piles or interlocks can come directly installed with it. Enquire to find out more with Mer Lion Metals Pte. Ltd.
This unique effect of WADIT®, even in low temperatures such as that in ground water, guarantees an excellent seal even in the event of torsion and other movement in the sheet pile wall interlock.
