Moldable Sealant Tape – 60 Mil Below-Grade Dielectric Putty
Moldable Sealant Tape is a 60 mil, gray, cold-applied dielectric putty tape engineered for below-grade waterproofing and surface contouring applications. This ambient-temperature sealant is specifically designed to fill voids, gaps, and irregular surfaces while forming a seamless, watertight barrier.
Its moldable composition allows installers to shape and press the material into complex geometries without heat or specialized tools.
Designed for Below-Grade Waterproofing
This dielectric putty tape performs exceptionally well in:
-
Foundation wall penetrations
-
Footing transitions
-
Pipe and conduit entries
-
Tie rod holes
-
Concrete irregularities
-
Structural joints
Once applied, the material conforms tightly to substrates, minimizing pathways for moisture intrusion.
Moldable, Gap-Filling Performance
Unlike rigid or thin adhesive tapes, this 60 mil sealant tape is engineered to:
-
Contour uneven surfaces
-
Fill surface voids and honeycombing
-
Bridge minor surface imperfections
-
Maintain flexibility under soil pressure
The non-hardening formulation allows the tape to remain pliable over time, helping accommodate minor structural movement and thermal cycling.
Dielectric Protection
The dielectric properties of the tape make it suitable for applications where electrical isolation or corrosion prevention is important, including:
-
Underground utility penetrations
-
Metal-to-concrete transitions
-
Protective wrapping systems
-
Cathodic protection interfaces
It can serve as a preparatory layer beneath protective wraps or geomembrane terminations.
Cold-Applied, No Heat Required
Moldable Sealant Tape is applied at ambient temperatures and requires no heating equipment, primers (unless specified), or mixing. Installation is straightforward:
-
Ensure surfaces are clean and dry.
-
Remove debris, dust, and loose material.
-
Cut to required length.
-
Press firmly into voids or against surfaces to achieve full contact.
-
Tool or mold as needed to achieve desired contour.
Proper surface preparation ensures optimal adhesion and watertight performance.
Key Performance Features
-
60 mil thick construction
-
Cold-applied installation
-
Non-hardening, flexible formulation
-
Excellent gap-filling capability
-
Below-grade compatible
-
Dielectric properties
-
Gray color for visual inspection
The thicker profile allows it to function as both a sealant and contouring compound in demanding structural transitions.
Typical Applications
-
Foundation waterproofing systems
-
Geomembrane terminations
-
Below-grade concrete joints
-
Pipe penetrations through containment liners
-
Repair of irregular substrate surfaces
-
Pre-fill under seam tapes or termination bars
It is commonly used in conjunction with geomembrane containment liners, seam tapes, and mechanical terminations to ensure continuous water barriers.
