Installation Guidelines

SWELLSEAL® for Sheet Piles should be applied onto a dust-free surface. The surface can be rough or smooth, moist or dry.

Refer to Installation Instructions for SWELLSEAL® for Sheet Piles.

Application Method

20 oz. Sausages: Put the sausage in the empty tube of the bulk caulking gun and cut 1/8 inch off of the top of the sausage. Close the tube and install the nozzle. Nozzles are supplied with the appropriate opening.

SWELLSEAL® for Sheet Piles must be applied in an uninterrupted band, gunned in the female sheet pile interlock.

If SWELLSEAL® for Sheet Piles is to be installed under water or during heavy rain, the caulked sheet pile interlocks need to be protected from rain and water to avoid premature swelling which may result in lowering the effectiveness of the material.

Health and Safety

Always use protective clothing, gloves and goggles consistent with OSHA regulations during use. Avoid eye and skin contact. Do not ingest. Refer to SDS (Safety Data Sheets) for detailed safety precautions

In the event of an EMERGENCY call:

CHEMTREC 800-424-9300.

Limitations

SWELLSEAL® for Sheet Piles must be fully confined on all sides to perform properly.

If unconfined, material may expand much greater than 200% and develop an open celled structure, which may result in leaks.

SWELLSEAL® for Sheet Piles is not suitable for surface caulking applications.

When applied at temperatures below 40 ºF, the material will have a significantly longer cure time, possibly exceeding several days.
