How to make a slope in a wood floor.

When installing a floor drain on most indoor floor surfaces it is important to slope the floor slightly so that water will flow toward the drain efficiently. Another tip to take you from diy to pro is to staple 15lb contractor paper felt tar paper to the sub floor before laying the planks to eliminate squeaking. Some even space every row when using diy plank or plywood. I try to make my pre slope the correct thickness at the drain so it will be 1 1 2 at the walls.

Another is to lay the planking perpendicular to the floor joists to prevent cupping bowing. Too much slope will create a poor feel to the floor and cause the unsettling sensation of the room being crooked. So if we make the pre slope 3 4 thick at the drain it needs to be a total of 1 1 2 inch thick at all your walls. It might also be difficult to find the right company to do the job.

This will be the height of your pre slope at the walls. Foundation issues deteriorating wood supports especially sills which rest on the foundation footer improperly installed joists or sub floors and other issues can all cause a floor to slope or sag. So mark a line 1 1 2 from the floor all the way around the wall studs. For example a floor that extends 4 feet away from the drain should have 1 inch of overall slope.

Failure to achieve adequate slope will result in standing water problems. For rooms that have a general slope the issue may be foundation problems that require the assistance of a foundation repair company or a general contractor. Except for that slope the floor itself might be flat.
