For the restoration of damaged balconies one first cleans away all the old concrete. A moulding (4) is mounted out from the house wall. Holes (5) are bored in the existing concrete joist (1) obliquely inwards and downwards. The boreholes are partly filled with hard plastic (6) which is allowed to run down to the bottom of the hole. A reinforcing iron (7) is introduced into the hole with a section (8) which pushes the floating hard plastic aside so that this fills up the gap (9) between the iron and the borehole's wall, where after the hard plastic is allowed to set. Finally concrete is poured into the mould which has been reinforced by the reinforcing iron.<IMAGE> |
