DonnaM in Welland has a house with a crawlspace. Donna noticed that the floors were getting out of level and had concerns for the safety of her home. The piers in the house were sinking and were not adjustable. 
Keith recommended add SmartJacks by Supportworks. Three Smartjacks were placed under the main beam of the house. The SmartJacks are fully galvanized and cannot rust. They are also fully adjustable in the case that further adjustments are required. 
Omni also removed debris and insulation to prepare for sprayfoam that is coming the following week.

This is not a basement job but it does involve waterproofing and repair of a wall that is shared between the house and garage that was poorly constructed. Basically, I think it is a patch job. Need to see it in order to explain properly. Requesting free estimate.
