Sixteen wicking beds are being constructed for the Honours wicking bed project. They are constructed in four IBC containers cut in half and then fitted with a divider across the middle of the half container. This allows two different materials to be trialled for the drainage layer in each half IBC.
The dividers have to be waterproof. The green material is bathroom waterproofing paint left over from our bathroom. It was painted onto fabric and corflute panels and allowed to dry.
It turned out that there was some leakage so pond liner was installed in the bottom of each wicking bed.
A range of materials are being used inside the pond liner so their effectiveness can be measured and compared.
