The workers first dug down to the footings of the building at the foundation walls, cleaned the walls of all debris, and coated the walls with a liquid sealant. Following the application of the sealant, they installed a rolled-type of moisture barrier followed by a sheet of water conduits. At the bottom of the ditch is installed coarse rock and drain tile to divert the water. The intent is to direct any water or moisture directly to the bottom of the foundation where the drain system will pick it up and allow it to drain into sumps that will then pump the water away for safe discharge.
This work should alleviate the water infiltration into the building on rainy days and when the snow melts in the winter. With some minor repairs on the inside basement walls things should be back to normal in no time!
I will update you on further repair progress as events dictate.
