Day 3: Emergency Foundation Repair
What happens here
Once the foundation blocks are pushed back into place, apply a generous layer of mortar or cement to the interior side of the blocks, filling all cracks and gaps. Use a trowel to spread and smooth the mortar, ensuring a thorough seal. The focus here is not on aesthetic tuckpointing but on fully mudding the wall to create a strong, waterproof barrier against moisture intrusion. Any excess mortar can be used to core-fill the interior of the blocks for added strength.
Goal: Seal all cracks and gaps in the interior foundation blocks with mortar.
