Description :

TT Swellmastic S2 is a grey, elastomeric, swellable system which is applied into a pre-formed rebate within the concrete construction joint or when used with TT Waterstop. TT Swellmastic S2 swells when it comes into contact with moisture.
preventing passage of water through concrete construction joints.

Uses :

• Fast curing.
• Sealing of joints in pre-cast manhole covers, cable ducts and service penetrations.
• Can be applied to rough surfaces.
• Sealing around H Beams or other steel columns which penetrate through concrete.

Advantages :

• Fast curing: Enables early concete pour and rapid return to service. Allows handapplied
• 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.
