Answer Details
The type of soil recommended for pond foundation is clay.
Clay soil is a fine-grained soil that is cohesive and has low permeability, meaning that it doesn't let water pass through easily. These qualities make it an ideal choice for pond foundation because it helps to retain water within the pond and prevent seepage.
Silt and sandy loam soils are not recommended because they are more porous, which can lead to water loss and instability of the pond walls. Sandy clay can also lead to seepage and instability, whereas humus is not a soil type but rather a layer of organic material that can be found on top of soil and is not suitable for foundation purposes.
