Description

Supercast SWX – Hydrophilic Water-Swellable Sealant

Description:
Supercast SWX is a grey, elastomeric water-swellable paste applied like a sealant. Its hydrophilic properties ensure consistent swell rates during repeated wet/dry cycles. On contact with water, the product expands, creating positive pressure against concrete joint faces to prevent water passage.

Uses:
Supercast SWX can be used as an adhesive for bonding Supercast SW strips or as a problem-solving hydrophilic waterstop in difficult access areas including:

• Sealing around joints in precast manhole covers, cable ducts and pipes, etc.
• Sealing around precast segments
• Sealing between rough surfaces, e.g., slurry walls and concrete slabs
• Sealing around H-beams and other penetrations through concrete structures
• Sealing around conventional rubber and plastic waterstops to provide ‘belt and braces’ seal prior to concrete pour

Advantages:

•  Fast curing: Enables early concrete pour and rapid return to service. Allows hand-applied concrete cover within 2 hours on emergency repairs and large-scale concrete pour after 8 hours
• Excellent seal on rough concrete: Gives improved water tightness. Plugs inequalities in rough concrete to produce a tight seal
• Excellent adhesion: Quick and easy to apply to a variety of uneven joint surfaces remaining firmly in place during
  concrete pour
•  Water swellable: Expands by 200% producing a watertight compression seal
• Durable: Excellent wet/dry cycling retaining elastomeric character and swelling performance due to high tolerance
  of the cementitious environment.

Application instructions
Preparation

Remove all obvious loose debris and soil, moss and organic growth from the substrate. Supercast SWX can be applied
to damp concrete but always ensure the surface is free from running water and brush away any standing or seeping
water. Divert running channels away from area before application.

Application:
Cut conical tip off cartridge end-thread, screw on nozzle and cut to required size. Place Supercast SWX into sealant gun
and apply like a conventional sealant. Extrude a bead of not less than 10 mm diameter onto the substrate, ensuring that
there is no break in the bead. Apply a 15mm bead when using as an adhesive for Supercast SW10/20.

Return to service:
After application, allow 30 minutes before re-establishing any running channels. A minimum of 2 hours (depending on
ambient temperature conditions) should be allowed before applying hand-placed concrete and 8 hours is recommended for large concrete pours where there is no guarantee that concrete will not be poured directly onto the seal. Supercast SWX should be protected from heavy rainfall whilst curing to prevent premature expansion.

Limitations
Supercast SWX should not be used for expansion jointing or for joints subject to significant repetitive movements.
Supercast SWX should be positioned to ensure that there is a minimum of 50 mm concrete cover to accommodate
pressure developed during the swelling process. Supercast SWX will establish a firm bond to the concrete however, as
with any hydrophilic waterstop, care should be taken during concreting to avoid pouring directly onto the product.

Estimating
Packaging
Supercast SWX is supplied in 310 ml gun cartridges (in a box of 20) and 600 ml sausages (in a box of 10)

Coverage
Each 310 ml cartridge will provide enough material for approximately 3.9 metres when gunned to form a constant 10 mm diameter bead, and 1.75 metres when gunned to form a constant 15mm diameter
bead.
Each 600 ml sausage will provide enough material for approximately 7.6 metres when gunned to form a constant 10 mm diameter bead, and 3.39 metres when gunned to form a constant 15mm diameter bead.

Storage
Shelf life
9 months.

Storage conditions
Store in original unopened cartridges and cartons in cool, dry conditions.

Precautions
Health and safety
Supercast SWX may cause sensitization by skin contact. Avoid contact with skin and eyes. Wear suitable gloves and
eye/face protection. Use only in well ventilated areas. For further information refer to Product Safety Data Sheet
