With the concrete in we needed to waterproof before putting in our footing drains and backfiling. We hired a company to spray an elastomeric material on the walls the seals off all the cracks and spaces. Then we had them install a drain board. The drain board helps the water so when it comes in contact with the wall it drains easily to the bottom where the footing drains pick it up and drain it around the house. Living in Washington, drainage is very important with the amount of rainfall we get.
