Wet Well Grouting

For Strengthening of concrete RCC, Columns, Beams, Slabs, Foundation etc. Execute the work as follows. Remove dust, laitance, grease, oil, curing compounds, waxes, foreign particles, coatings and disintegrated materials by mechanical means (i.e., blast cleaning). Empty entire pre-packed and pre-weighed contents of ‘B’ Component into pail containing ‘A’ Component. Mix for 30 seconds with a low speed stirrer. (400-600 rpm). After proper mixing of component ‘A’ and ‘B’, now empty entire pre-packed and pre-weighed part ‘C’ component into the mix and using a mechanical stirrer mix all the components for 1-3 minutes with a low speed stirrer (400 to 600 rpm). Caution: Mix only that limited quantity which can be placed within the pot life. Material should be quickly brushed/ poured from pail onto concrete surface to obtain prolonged working life. Inspect the underside for evidence of full depth cracks that may require additional treatment to prevent draining of the resin. Cracks greater than 1/8" width should be repaired individually. Fill 1/8" or larger cracks with loose sand and pour small quantity of mixed 2-(methoxycarbonyl)-1-Propene Resin Sealer Cum Grout as approved by Engineer in charge into the crack, allow to cure. The above Material is spread evenly on the surface as a flood coat with a squeegee or rollers on horizontal and vertical surfaces and allowed to absorb completely into the concrete substrate. Drill injecting holes to a depth of 2 - 4” in concrete depending upon the width of crack, extent of damage and dimension of structural element. Fix the grouting nozzle and inject the mixture of 2-(methoxycarbonyl)-1-Propene Resin Sealer Cum Groutat pressure of 50 - 100 psi. (Rate for fixing nozzle is not included in this item).
