Flexstrip 120

Fabric-coated waterproof elastic joint sealing tape

Drykos® Flexstrip 120 is a waterproof joint cover tape consisting of an elastomeric core with high deformation capacity, fully coated on both sides with absorbent fabric. The presence of the textile coating allows for excellent impregnation and integration with cementitious waterproofing systems, ensuring high adhesion to the substrate and the creation of a continuous and durable system. Thanks to its high elasticity and ease of application, Drykos® Flexstrip 120 is particularly suitable for sealing and waterproofing joints in surface waterproofing systems.

Main features
  • High deformation capacity and adaptation to substrate movements
  • Excellent water impermeability
  • Fabric coating to improve adhesion to cementitious systems
  • Easy impregnation with waterproofing mortars
  • Simple and rapid application
  • High compatibility with osmotic systems and elastic mortars
  • Good mechanical resistance and long-term durability
Fields of application
  • Connection joints between horizontal and vertical surfaces
  • Expansion joints in surface waterproofing systems
  • Connections between structural elements
  • Waterproof coatings with elastic mortars
  • Damp environments (bathrooms, technical rooms, balconies, terraces)
  • Tanks, reservoirs, and concrete surfaces
Packaging
W 120 mm - 50 m roll
Color

Gray.

Storage

The product has no storage limitations if correctly stored.

Storage conditions

Store in original intact packaging in a cool, dry environment, protected from frost, humidity, and direct exposure to sunlight.

Theoretical consumption

~ 1.1 m of tape for every linear meter of joint, considering an overlap between the edges of approximately 10 cm to ensure the hydraulic continuity of the system.

Yield

~45 linear meters of joint per roll.

Application temperatures (substrate and environment)

Minimum +5 °C | Maximum +35 °C

Substrate preparation

Application surfaces must be clean, solid, and free of dust, loose parts, oils, or contaminants that could compromise adhesion. The substrate must be thoroughly roughened and prepared to ensure adequate anchoring of the waterproofing system.

Application

Drykos® Flexstrip 120 must be applied in combination with elastic waterproofing mortars such as Drykos® Drylastic or Drykos®Drytop. Proceed by applying a uniform layer of mortar to the substrate, with an adequate thickness and a width greater than that of the tape. The tape is then positioned on the fresh layer and pressed carefully to ensure the complete embedding of the fabric into the applied material. Subsequently, cover the Drykos® Flexstrip 120 tape with a further layer of the same waterproofing product, ensuring the continuity of the system and the complete sealing of the joint.

Other indications
  • Apply the product exclusively to adequately prepared substrates.
  • Ensure complete impregnation of the fabric into the waterproofing mortar.
  • Ensure the continuity of the system through correct overlapping of the tapes.
  • Avoid application in unsuitable environmental conditions (frozen surfaces, presence of free water).
