Installing EnviroSCAN, EnviroSMART & Diviner 2000 access tubes

Step 3 – Make the slurry

Slurry Recipe

• 1 part grey cement.

• 4 parts kaolinite (potters clay as fine powder).

• 5 parts water

To mix the slurry on site, either take sufficient quantities of each slurry ingredient and suitable measuring

utensils to the site or pre-mix the dry slurry ingredients and store them in a plastic container.

1. Measure out 4 parts kaolinite and 1 part cement and mix in a plastic container.

2. Slowly add water and stir with the paint stirrer until all the solids are completely suspended in the

mixture. Ensure that no free water is separated from the solids and no dry lumps are left. The

consistency of the slurry should be similar to that of a milkshake. The slurry has a working life of

approximately two hours.

The quantity of slurry required will depend on the size of the access tube hole and the type of soil. The

diameter of the access tube hole will vary depending on the quantity of stone present.
