A method for renovation of surface dressing around well curbs

摘要

A well curb (2) is lifted to a first position, whereafter a compressible device (12) is positioned around the well curb (2). Hereafter the well curb (2) is lowered to a second position so that the compressible device (12) is abutting the upper edge (13) of the well (9), whereafter a casting material (14) is injected into the cavity between the surface dressing (4) and a filling (17) around the well (9). Finally the well curb (2) is lowered to its final third position.
