Vetonit remokor L-45 — pourable non-shrink repair mortar, class R4
Class R4 flowable mix for concreting densely reinforced and prestressed structures in formwork where shotcrete is impossible; 45 MPa.

Hydraulic structures, cement concrete pavements of roads and airfields, beams, piers and bridge slabs are repaired without heating in frost down to −10 °C with Vetonit remokor TS-60. The thixotropic class R4 mix is applied by spraying with a plastering machine or with a trowel without formwork, including on vertical and overhead surfaces, onto a primer coat of the same mortar. After 2–3 h at +20 °C foot and vehicle traffic is allowed; the compressive strength at 28 days is at least 60 MPa, water impermeability W16.
