Gidroteks-Sh (joint) — non-shrink mix for joints and abutments

Cementitious coating waterproofing

The joint mix of the Gidroteks system fills opened-up floor–wall and ceiling–wall junctions, cold construction joints, concrete block joints, service penetrations, technological openings and cavities to their full depth. It is used when there is no active water seepage, and the main waterproofing is done no earlier than 3 days after filling; the compound is not suitable for expansion and temperature joints. The non-shrink material has a watertightness grade of at least W16, compressive strength of at least 45 MPa and bond to concrete after 28 days of 2.8 MPa.
