Install Pond Liner for Moisture Protection

What happens here

Following the structural wall, a pond liner is installed along the house-facing side of the raised planter, covering the concrete blocks and extending down to the base. The presenter explains that this liner acts as a critical moisture barrier, preventing water from the soil in the planter from reaching and damaging the house's wooden elements (which could rot) or its foundation. Any water that permeates the soil will hit this membrane and be directed downwards, away from the structure.

Goal: Protect the house structure from moisture damage.
