WebThe sand filter is generally built with its top just above the final grade of the surrounding area, but sometimes its side walls may be exposed, when they are built of concrete. The top of the sand filter is covered with permeable soil, generally planted with grass, to allow air flow to the sewage effluent in the sand filter. WebHoggin is a mixture of sand, gravel and clay and when compacted together makes a very stable, buff coloured surface. For this reason, it is used as hard core in roadbuilding. Hoggin is easy to maintain as it permeable, allowing water to filter through it, is environmentally friendly and is aesthetically suited to all types of properties. WebThe most important property of pervious concrete is its water permeability. Currently, there is no standard experimental procedure to determine to this property.
