Complete Interior Mortar and Exterior Clay Cap
At 8:56 in
Day 3: Emergency Foundation Repair
What happens here
After addressing the exterior, return inside the garage to complete any remaining interior mortar work on the cinder block wall. This includes applying mortar to any areas missed or for final smoothing of the joints. While one person is finishing the interior, another worker can begin laying down a clay cap over the exterior gravel layer. The clay cap consists of native soils high in clay content, which holds together and retains moisture on the surface. This cap helps to shed surface water further away from the foundation, complementing the drainage aggregate below. The clay soil is spread and compacted on top of the gravel, then graded to direct water flow.
Goal: Finish interior wall sealing and install a protective clay cap over the exterior drainage system.
