Poured concrete shall be excluded from the wetted channel for a period of 30 days after it is poured. During that time, runoff from the concrete shall not be allowed to enter a live stream. Commercial sealants may be applied to the poured concrete surface where difficulty in excluding water flow for the 30-day period may occur. If sealant is used, water shall be excluded from the site until the sealant is dry and fully cured according to the manufacturer’s specifications.
