Over a period of years, as they fill with mud, silt and plant materials, many ponds and lakes will require desilting. De-silting might also be needed when there is a large accumulation of semi-decomposed leaf litter and other organic debris. This material tends to reduce oxygen levels in the pond or lake, and because it often produces acidic conditions, it can reduce the fertility of the pond or lake.

In ponds that have become very shallow as a result of silt and organic debris, fish stocks will be at risk and moralities may occur.

Desilting is undoubtedly an art form, but, with specialist machinery and skilled operators, HFF-Construction is able to successfully desilt all types of ponds and lakes.
