Case Studies


Most common WADIT® applications include:


1. WADIT® is tested and certified to keep water out and withstand 5 bars of pressure

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.

2. Optimal flexibility

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.

3. Environmental: No harmful effects to the environment

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)).

4. Once installed it is impervious to weather

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.

5. Unique durable bond

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.

6. WADIT® can be delivered already installed in the sheet piling interlocks

The mill or distributor where you buy your sheet piling can also deliver the sheet piling with WADIT® already installed. This may not be available with all types of sheet piling in all areas. (Please call PilePro® at 866-666-7453 / 512-243-1228 to find an authorized WADIT® installer in your area and/or to receive a quote for PilePro® to carry out the WADIT® installation).

7. Memory effect = material rebound after movement

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.

Frequently Asked Questions

Why should I use WADIT?

WADIT sealant is impermeable, when applied correctly by a professionally trained crew. Once installed the contractor will having nothing to worry about and be able to install the sheet pile normally without restrictions or special concerns regardless of the driving method or environment.

WADIT© is the only sealant on earth that is made solely for sheet piling and all of the behavioral requirements that sheet piling has.

How do you know you are really getting WADIT ?

If you receive a WTR (Wadit Test Report) which shows all the particulars of the exact material and installation details.

Which includes receiving a WADIT certificate at the completion of your job proving that its truly a WADIT certified job to include the material and installation process.

Why does WADIT work well in sheet piling?

WADIT is flexible and thus offers unique elasticity. Other swell type sealants material become rigid and fracture which may cause leaks. WADIT tolerates torsion and movements in the sheet pile interlock maintaining an absolute seal.

Is WADIT impermeable?

WADIT sealant is impermeable. If a professional trained crew using the correct procedures, including sheet pile penetration, applies it correctly into a sheet pile, then the joint will have no permeability. Laboratory tests have substantiated the impermeability of WADIT when correctly applied to a sheet pile.

How far under water can you install WADIT?

WADIT underwent extreme tests and was subjected to a maximum water pressure of 5 bar (= 500 kPa, or more than 130 feet of water pressure depth) which represents almost twice the safety margin over maximum water pressure levels measured in the past. In the opinion of those involved in the tests, WADIT would in fact have withstood an even higher water pressure.

Does WADIT help corrosion?

Yes. The inside of an interlock is what you see on a coated sheet pile wall that rusts quicker when you don't use WADIT.

Can you drive WADIT immediately, soon after installation?

Yes. By the time it takes to pick up the sheet pile with the crane to put it into the ground, WADIT is ready.

How long can you store steel sheet pile with installed WADIT?

Indefinitely. There are no restrictions.

Can you install WADIT in cold formed interlocks?

WADIT can be used/installed with any and all sheet pile types, hot or cold rolled, paired or unpaired, that are currently on the market today.

Can we test WADIT against our contaminated soil conditions, just to be sure there are no concerns?

Yes, this can be arranged for a fee that is applied against your eventual order, which we did, for example, on a study on Creosote.

Can you install WADIT in frozen conditions?

Yes. WADIT© remains flexible in temperatures below 20 degrees Fahrenheit.

Can you install WADIT in high heat or the desert?

Yes. WADIT does not become viscous until temperatures over 250 degrees Fahrenheit.
