Gidrobeton-Podvodny — flowable mortar for repairing structures under water
Gidrobeton-Podvodny is intended for structures located under water and in the zone of variable water level: port structures, bridge piers, hydraulic engineering facilities. The flowable mix with aggregate up to 10 mm and polypropylene fibre is fed by gravity or by mortar pump through a hose into the lower part of sealed formwork, where it displaces the water without being washed out. The manufacturer states a compressive strength of at least 45.0 MPa at 28 days, watertightness W18 and high resistance to sea water.
