# How to Improve Drainage on a Concrete Patio
Heavy rainfall or sprinkler use can cause water to build up on a concrete patio. Excess water can cause concrete discoloration and pitting, and it may also damage nearby house structures. You can improve patio drainage by relocating water sources, applying a waterproofing sealer and installing drainage mats.
Things You'll Need
- Scrub brush
- Plastic sheeting
- Waterproofing sealer
- Garden sprayer
- Paint roller
- Drainage mats
Instructions
-
-
1
Move sprinklers and plants located near the patio to prevent water from spraying or draining onto the concrete.
-
2
Clean the patio thoroughly with soap, water and a scrub brush to remove dirt and grime in preparation for sealing. Allow the patio to dry completely before you apply sealer.
-
3
Mask the ground and walls around the patio with plastic sheeting to protect them from the sealer.
-
4
Spray an even coat of sealer over the patio. The sealer will prevent the patio from absorbing water, which will encourage water to run off the sides.
-
5
Roll a paint roller over the sealer to distribute it evenly into the concrete.
-
6
Place drainage mats around the patio, or build up soil in slopes around the edges of the patio to force water to drain away from the house.
