This fine damp leam is slightly binding and grey in colour. It is perfect for lakes and slow flowing rivers. Often used in canals to create a carpet on the bottom over which to introduce your groundbait. Damp Leem is used to make any type of groundbait heavier, helping it to sink faster in deep or fast moving water, as well as aiding in its breakdown once it has reached the bottom. It is also a good carrier and separator for live and dead joker.
