REKS® Strukto 100 — thixotropic R4 repair mortar resistant to acidic media
Non-shrink fibre-reinforced R4 mortar for bridges, tunnels, dams and treatment plants, tested for resistance in liquid acidic aggressive media.

Injection of cracks and pores in concrete to restore load-bearing capacity, including where erosion is severe, is carried out with REKS® EPO INZH. The two-component low-viscosity amber epoxy protects and strengthens load-bearing concrete structures and brick masonry; the viscosity of the mixed components is no more than 400 cP, and the gel time is from 30 minutes. After 7 days compressive strength is at least 70 MPa, tensile strength from 25 MPa, adhesion to steel at least 6 MPa; 5 and 10 kg kits in metal containers.
