We are presently excavating and running into a water problem. I understand there is a product that you place down on the foundation before you lay your first row of block that acts as a water seal at that point. I do understand that on the outside you must place a perforated pipe. There is also a product that is like a board that you place on the outside of the blocks that acts as a funnel for the water. Water will go through it but dirt and sand will not. Can you tell me the names of these two products?
Thanks.........need the answer QUICK!, naturally, don't we all.
