REKS® AR FM — R4 repair mortar for wet spraying, supplied with fibre
Thixotropic class R4 mortar for repairing bridges, tunnels and columns by spraying or trowel; each bag comes with a pail of fibre, flexure from 12 MPa.

The dispersed grout REKS® Grip Ultra fixes timber and concrete sleepers and sleeper blocks in track concrete, fills cracks and cavities, and is used for installing railings, posts and signs and for fixing rebar. Its aggregate size is 0.16 mm, initial flowability is retained for 8–20 minutes, and shrinkage or expansion strain at 28 days is no more than 0.1/0.05 %. Compressive strength is at least 10 MPa after 2 hours, 25 MPa after one day and 52 MPa after 28 days; packed in 19 kg bags.
