Insect InvasionStanding water attracts insects, particularly mosquitos, which are enough to ruin any outdoor experience.
MoldPoor drainage seeping water into basements or crawlspaces will create mold, leading to poor air quality and damage to structural elements. It also causes mildew, which could damage your pavers.
Drowned PlantsPlants need water, but too much will kill them. Poor drainage can cause root rot and plant death.

What are the main patio drainage options?

Here are some options for draining water from your patio. Be sure to watch the videos for better understanding!


Why not use nature’s advantages when designing your outdoor space? If you set a proper slope and grade of at least a quarter-inch per linear foot, water should flow away from the areas you need to protect naturally without much more work on your part.

French drain

If your patio site doesn’t have enough natural drainage, consider adding a French drain, one of the effective patio drainage options, to channel the water where you want it. A French drain is a covered trench holding a perforated pipe and aggregate (gravel) to redirect water.

A French drain is an excellent option if you’re concerned about the aesthetics of your patio. You can match the aggregate to the rest of your patio, and the drainage trench adds an attractive border to your outdoor area.

Permeable pavers

For your patio, permeable pavers are another way to integrate drainage into your aesthetic design. Take advantage of the land’s natural water absorption for sustainable landscaping choices. You also have the option to use permeable grass pavers, which incorporate living plant material to help harvest and recycle rainwater while preserving green space. You can also include permeable pavers in French drains.

Common patio drainage problems and solutions

These are some patio drainage problems you may have.

Improper pitch

A level patio may seem appealing, but it can become a haven for water accumulation and subsequent damage. This standing water not only poses a risk of water damage but can also lead to the growth of mold and algae, making the surface slippery and unsafe. To counter this, during the design phase, it’s crucial to integrate a gradual slope away from your home and other structures. This subtle inclination, often imperceptible to the eye, is a key design feature that facilitates proper drainage, directing water away from your patio and home foundation. 

Clogged drain system

Drainage systems in older patios are particularly susceptible to clogs from leaves, twigs, and sediment buildup. Over time, these obstructions can significantly impede water flow, leading to surface water accumulation. Regular inspection and cleaning are essential, especially after storms or seasonal changes. In severe cases, professional cleaning or even system upgrades may be necessary. It’s also important to consider the surrounding landscape – trees and plants that shed leaves or needles can contribute to frequent clogs, necessitating more frequent maintenance.

Badly placed downspouts and roof overhangs

The positioning of downspouts and roof overhangs relative to your patio can dramatically affect drainage efficiency. Incorrectly directed downspouts can funnel water directly onto your patio, overwhelming the drainage system. To mitigate this, it’s essential to consider redirecting downspouts away from the patio or integrating them into the existing drainage plan. This might involve extending downspouts, installing diverters, or even incorporating rainwater collection systems that can be used for gardening purposes, turning a problem into an eco-friendly solution.

Sinking pavers

Paver erosion and sinking are telltale signs of underlying issues, often indicating the need for better patio drainage options. This is usually due to an inadequate base or sub-base that fails to provide proper support and drainage. To address this, it’s necessary to excavate the affected area, removing not just the pavers but also the top layer of soil, which may have become saturated and unstable. Replacing this with a well-compacted layer of gravel or crushed stone creates a more stable base, facilitating better water dispersion and preventing future sinking. This process not only addresses the immediate issue of sinking pavers but also enhances the overall drainage efficiency of your patio area.
