The Swell Caulk Hydro Active Joint Seal Principle

When in contact with water, SealBoss SwellCaulk Sealants develop an expansive swelling pressure. The pressure between the expanding product and the surrounding concrete structure creates a compression seal and prevents the penetration of water through the joint providing a durable waterproofing solution.

Product Description

SealBoss ® SwellCaulkTM is a single component, hydrophilic, gungrade waterstop. The product is formulated for sealing construction joints, pipe penetrations and other concrete joints of smooth and uneven surfaces. Material cures and swells in the presence of moisture or water thereby creating a compression seal.
Curing time decreases with higher temperatures and greater relative humidity. SealBoss ® SwellCaulkTM will cure in approximately 24 to 36 hours depending on ambient climate. The prodcuct is supplied in sausages or in cartridges. The product is for professional use.
SealBoss ® SwellCaulkTM can be used as an adhesive for SealBoss  SwellTapeTM, joint waterstop system, see corresponding data sheet.

Installation Guidelines

SealBoss ® SwellCaulk should be applied to a dust-free concrete surface which can be uneven, rough, smooth, moist or dry. Apply in an uninterrupted band/bead (minimum 1/2″ or 12mm wide and high), placed in the middle of the joint or prefab element (minimum concrete cover is 3″ or 7cm). In case of fresh concrete, SwellCaulk should be covered by at least 3″ or 7cm of concrete on both sides for best results and to avoid cracks from the expansion pressure of swelling product.

310ml Cartridges

Break the moisture-proofing aluminum foil on the top of the cartridge, screw on the nozzle and cut diagonally at the appropriate position. Place the cartridge into caulking gun.

600ml Sausages

Put the sausage in the empty tube of the caulking gun and cut 1/2″ / 1cm off the top of the sausage. Close the tube and install the nozzle. Cut the nozzles diagonally at the appropriate position.

Sheet Pile Applications

SealBoss ® SwellCaulk is designed to seal sheet pile knuckles by application of SealBoss SwellCaulk in an uninterrupted band, gunned in the  female sheet pile interlock before driving the sheet piles. The caulked sheet pile interlocks need to be protected from rain and water to avoid  premature swelling. SealBoss SwellCaulk must be fully confined on all sides to perform properly.

Packaging
