Tips To Prevent Standing Water On Patios


Water can be a real concern when you are installing a patio. You don't want water from rain or irrigation to pool on the patio, since this can weaken the materials or lead to unsightly moss growth. Collected water is even more of a problem on patios next to the home or garage, since the water can flow toward the building and cause foundation problems. The following design tips can help you avoid this issue.

Tip #1: Opt for a permeable option

Water won't collect on top of a permeable patio. There are several ways to skip the impenetrable concrete slab and create a permeable surface that allows moisture to seep through and drain.

  • Use paver block construction. This consists of paving stones with sand filling the joints between each one instead of mortar. Water can drain slowly through the sand joints.

  • Install grass permeable pavers. This uses a similar construction method as paver blocks, except the pavers have open spaces between them that allows grass to grow. The result is a semi-hard surface with good drainage.

  • Combine concrete and gravel. This looks decorative at first, but serves to provide drainage. A concrete pad is laid but it has trenches in it, often around the inside perimeter of the shape. This trench is filled with gravel. Collected water settles in the gravel trenches where it can drain.

Tip #2: Consider the grade

A poorly graded patio is more likely to have drainage issues. The grade is the slope of the patio. You don't want a perfectly level patio, since water will sit on the surface without running off. Instead, you want the patio to slope gently away from any buildings – preferably toward a grassy area or an area with a storm drain.

Dips in the center of the patio can also lead to water collection and eventual patio problems. This is why the grade slope should be in one direction to avoid central dips.

Tip #3: Install a drain solution

Drainage can be important for a patio, especially if you don't want to install an obviously permeable option. A French drain installed on the downward slope side of the patio can route water away from the area. This is simply a perforated pipe buried at the edge of the patio. Gravel or loose fill is placed over it so that water can easily percolate into the pipe.

On paver patios, a base grid is a good option. These rubber grids sit beneath the paver stones. Not only do they create a sturdy base, but they also provide space for the water to drain beneath the pavers.
