The key points of grouting material secondary grouting operation - Low thick self-leveling grouting material construction

grouting secondary grouting material manufacturer self-leveling grouting grouting material in the construction site for a certain amount of water, stir well after use.

The granularity of the gravel is about 5 ~ 15 mm, cement with 400 or 500. 3, grouting, should put a circle of external formwork grouting material packing plate, the edge of the edge from the equipment base is generally not less than 60 mm; If the equipment under the base of the whole area without grouting, and grouting layer need equipment under load, still need to put inside the template, in order to ensure the quality of grouting layer. Within the template to distance should be greater than 100 mm of the outside of the equipment base, also not less than the base surface edge width. Grouting layer height, outside the base should be high on bottom of base grouting material suppliers. Grouting layer on the surface should be slightly slope ( Outward slope) To prevent oil and water into the equipment base. 4, grouting operation shall be used, cannot interrupt, poured out at a time.
