Problems people face when they see a crack in the foundation wall is alarm and fear. Their first reaction is that the house is going to come crashing down on them while they are sleeping.
So when SQ Consultants get called for a job related to foundation cracks is to listen to the client. The client instead of being specific about the problem try to go around the problem.
Our first job is to clarify that the house is not going to crash which is true for most of the cases. Than explain why the crack has happened it could be as simple as bad grading on the outside or bad soil used as backfill.
Some of the remedies are simple like redirecting water away from the foundation or removing expansive backfill and replacing it with granular soil.
