BRONCO® HYDROSWELL MASTIC is an off white gun applied mastic with good adhesion to concrete steel, glass, PVC, HDPE in contact with water, BRONCO® HYDROSWELL MASTIC will expand up to min 250% and provide a durable joint sealant with constant adhesion and expansion features.

Advantages

• A double sealing action, which combined with its self adhesive property.
• Can be placed on damp or uneven surfaces and functions in a wide range of temperatures and ground conditions.
• When applied on smooth or uneven surfaces its tack and filling properties produce and initial seal.
• It will expand to increase the sealing pressure and prevent water leakage.

Area Of Application

• Sealing joints in cast in place concrete (even on rough surfaces).
• Sealing joints in precast segments (i.e. manholes, box culverts, cable ducts and pipes).
• Sealing around steel H‐beams.
• Bonding strip sealants to rough surfaces.
• Sealing around bolt spacers and void formers
