How to make a simple Waterproof Repair Pit for car repair !

In this video I will show you how to make a waterproof repair pit for car repairs at home.This is how I made it and it's 100 percent tried. The pit is dry all year round. Before, I had a pit in which water was constantly flowing during the rains, but this is really something else!

You're supposed to make the walls first and then after they've hardened, pour the floor so that the walls will compress onto the floor when under load.

Multiple problems with this one: too thin walls, no water drainage, too narrow.
