TamSeal SM is a one component hydro reactive expansion sealant for waterproofing joints in concrete. It is applied using a skeleton gun.

TamSeal SM expands up to 100% when in contact with fresh water to create a durable waterstop with long-lasting adhesive and hydro-swelling properties.  When in contact with sea water, TamSeal SM expands between 50 – 70%.

TamSeal SM has excellent adhesive properties on different surfaces such as concrete, steel, glass, PVC, HDPE etc.  The surface can be rough, smooth, damp or dry.
