We have added an addition with a basement. The soil is clay but we have a good slope leading away from our house. Never have standing water. We have had water come through our walls and stain them. The footer tiles seem to be working but water is still staying in the blocks. If we water proof with a sealer inside is there a chance that water will sit in the blocks and create bigger problems in the future. The outside has already been dug up and sealed twice. WE were told clay soil often times has block basements that leak water. But our fear is that the water proofing sealer will not solve a bigger problem we might have. any ideas.
