Description

In addition to the sealing of natural dams, sodium bentonite is often specified for applications including as a seal in the base of root barrier.

When using bentonite as a base for root barrier using a mixing ratio of 1:15 (bentonite to soil) for good quality soil or 1:10 ratio for poorer earth. Bascially you will need approximately 5kg per 10m of root barrier, allowing for a 50mm depth x 100mm width of bentonite/ soil mix.

If you are using bentonite clay for earth dams a common mix is 20kg soil to 1kg bentonite.
