Where To Lay Down Exterior French Drain?

Answer:

Dig a trench along the outside of your footing. The trench should be at least 2 feet wide, and can be as deep as 6 feet for a basement or as shallow as two feet for a slab-on-grade home. Lay the pipe on the virgin soil.

Answer:

Place the drain with the drainage holes face down in the trench. Lay the pipe in the trench so the slotted holes face downward, as this allows the water to flow through the pipe into the draining site. Make sure you have enough pipe to fill the length of the trench. The pipe should sit snugly in the gravel.
