Silt build up is most commonly caused by the decay of organic material on the lakebed, leaf matter from trees, old weed and fish waste. Over many years the build up of these products can create deep smelly silt deposits which can be harmful to the chemical makeup of the water and can drastically reduce the depth of the lake over time.
We can take care of the removal of silt from your venue. To obtain the most effective results we would recommend using excavators and dumpers but this does involve fully draining the lake first.  In situations where it may not be desirable to drain the lake we can use silt pumping machinery or long reach excavators as an alternative. A site inspection will help us to advise you on the best method to use.
We also can help manage the build up of silt by applying micro-chalk to the lake which helps to break down the organic matter and reduce harmful gasses within the silt layers. Micro-chalk is a highly porous calcium carbonate that is environmentally friendly, harmless to fish, plants and all other aquatic inhabitants. The product also counteracts the acidity of the water and adds a source of calcium which increases the biodiversity and productivity within the water. Whilst micro-chalk can be used as a one off application it works best as part of an annual maintenance plan and we would be happy to work with you to implement this.
