SikaSwell® A

ACRYLIC-POLYMER-BASED RANGE OF SWELLABLE, JOINT SEALING PROFILES

SikaSwell® A is a specially formulated range of high-performance, swellable, acrylic profiles for the waterstopping of all kinds of construction joints. When in contact with water, or certain solutions, the profiles expand to form a compression seal, blocking the passage of water and liquids.

  • Easy to apply
  • Can be installed onto different substrates
  • Highly economical and quick to install
  • No hardening time required
  • No welding required
  • Adaptable to fit different detailing
  • Range of types and dimensions available
  • Swells in contact with water and liquids
  • Can swell into cracks and gaps
  • Resistant to water and various chemical substances
  • Long-term reliablility tested
  • Independent assessment of SikaSwell® A profiles includes:
    - Function application in construction joints: Wissbau® Consulting Engineers : 2002-094.
    - Testing of material and swelling properties: Material Testing Institute of Northern Rhein - Westfalia (MPA NRW).
    - Mechanical long time stability: FH Aachen - University of Applied Sciences.
    - Resistance to water pressure and durability (SikaSwell® A-2010): British Board of Agrement 13/4994.

Application steps

SUBSTRATE QUALITY

The surface to which the SikaSwell® A profiles are to be installed must be sound, clean, dry, free from all surface contaminants.

SUBSTRATE PREPARATION

All loose particles, release agents, laitance, paint, rust and other poorly adhering materials must be removed by suitable hand or mechanical preparation. Surfaces which are excessively rough tend to leak eventually. It is recommended to smooth rough areas with fresh concrete mortar.

CLEAN UP

Uncured adhesive material can be removed from equipment and tools using Sika® Urethane Thinner and Cleaner. Cured adhesive material can only be removed manually or mechanically.
