Preparing to pour footings. The concrete is delivered from the concrete truck via a chute to wheelbarrows and then manually placed. The grid between the form boards is iron rebar that are tied together with steel wires. This serves to reinforce the concrete.
Lower level has been backfilled with “CA-7",” which is a graded crushed stone. That is, the stone are of relatively uniform size. What looks like Kraft paper laid over stone, is actually a product called Cetco Ultraseal. This is a multilayered waterproofing material that combines natural sodium bentonite and a chemically resistant hydrophilic polymer to form a bentonite-polymer alloy (BPA). The is material has swelling properties that seal small concrete cracks. The “paper” is simply overlapped.
