Mapeproof Swell (Pack of 6)

Hydro-Expansive, Rubber-Based Hydrophilic Sealant Paste

6 x 320ml

Mapeproof Swell is a rubber-based hydrophilic sealant supplied in convenient tubes, designed for precise application using a standard extrusion gun. When it comes into contact with water, the product swells to form a highly effective seal, helping to reduce the risk of water migration in critical construction joints.

Suitable for waterproofing detailing around penetrations, construction joints, service entries, vertical wall/ slab interfaces and complex geometry areas where preformed profiles are difficult to seat cleanly. The paste format provides a controlled bead that allows for better contact, continuity, and more accurate placement than traditional rigid components in restricted or difficult site conditions.
