GeoTek SJ


The GeoTek SJ has been specifically developed for lifting, re-levelling, support, and void filling. An exceptionally strong resin for re-levelling and slab lifting, the SJ has extremely fast reaction times and superb bearing capacity. It quickly polymerises to form an expansive, high strength foam, generating lift and instant support for safe infrastructure, utilities, commercial, industrial, and residential projects.

GeoTek SJ is based on a polymeric MDI (Part A ISO) and a polyol component (Part B Polyo). When mixed, a super-fast reacting polyurethane foam is formed which is tough, rigid and resistant to a wide range of chemicals. Controlled expansion and high early strength allow this material to be used effectively for raising sunken slabs and pavements.
