Assuming it is the case of weepage between concrete layers, attention needs to be paid to the preparation of existing surface before placing the next one - keeping it moist, use of bedding concrete on all or part of the dam width (highly sanded mix with a bit more cement - some coarse agg - typically to achieve 150mm or so of slump. Cold joints (where successive layers are placed more than a day or so later need special treatment (air/water pressure spraying or wire brushing). Outer surfaces to be kept moist for say a month after placement. No curing compounds on the layering.
