▶️ስለ Grouting አብረን እንይ

👉Grouting is a method of filling up and repair of cracks in concrete.
Step by step grouting procedure needs to be followed for effective repair of concrete cracks.
Grouting Procedure for Repair of Cracks in Concrete Structures: Procedure of grouting for repair of concrete cracks in structures are:
1. Holes are drilled in structure along cracks and in an around hollow spots.
2.If there are several cracks, holes can be drilled in a staggered manner at 500 to 750mm spacing in both directions covering adequately the area proposed to be grouted.
Holes spacing can be altered as per site conditions.
3. G.I. pieces (12 to 20mm dia x 200mm) with one end threaded or PVC nozzles are fixed in the holes with rich cement mortar.
4. All the cracks and annular space around G.I. pipes are sealed with rich cement mortar.
5. All the cracks are cut open to a ‘V’ shaped groove, cleaned & sealed with rich cement mortar.
6. All the grout holes should be sluiced with water using the same equipment a day before grouting as per following sequence; so as to saturate the masonry.
All holes are first plugged with proper wooden plugs or
locked in the case of PVC nozzles. The bottom most
plug and the two adjacent plugs are removed and
water injected in the bottom most hole under pressure.
When the clear water comes out through the adjacent
holes the injection of water is stopped and the plugs in the
bottom most hole and the one immediately above are
restored.
The process of grouting of concrete cracks is repeated with other holes till all the holes are covered.
On the day of grouting all the plugs are removed to drain out excess water and restored before commencing grouting.
The same sequence as described above is adopted for
injecting the cement grout also.
The grout is kept fully stirred/ agitated under pressure throughout the grouting.
The grouting is carried out till refusal and/ or till grout starts flowing from the adjacent hole.
A proper record of the quantity of grout injected into every hole should be maintained.
After grouting, curing should be done for14 days. Tell tales
are provided for checking the effectiveness of grouting.
Only such quantities of material for preparing grout should be
used, as can be used within 15 minutes of its mixing. Grouting equipment must be cleaned thoroughly after use.
