 Not having a drainage system also causes your Patio to be swamped with water. This is because, after heavy rainfall, the water cannot roll off into a drain, so it stays that way instead of being drained.

Drainage Systems To Consider

If you do not have a drain in your yard or want to put in more drains, here are options you can consider.

1. Rain Barrel

If you have an empty barrel not being used, you can place it directly underneath your gutter or downspout to collect water instead of spilling it around.

The advantage of this method is that the water you collect is useful and can be used later on; however, this method is not suitable for heavy rainfall as the barrel will overflow.

2. Channel Drain

A Channel drain is a great setup if you aim for a drainage system that adds to the good look of your yard. This drainage system is great if your surrounding area is asphalt or concrete. The water that flows through this channel flows in another direction.

3. Catch basin

This flat drainage system with in-ground pipes leads the water elsewhere. It is better installed just below your gutter to prevent water from pooling around that area, and it should be covered with a mesh to prevent debris from clogging the pipes.

4. Downspout extension

This is another way of channeling water away from the ground below your gutter. You can attach an extension that leads the water to a place farther away from where they flow properly. This method prevents the ground surrounding your gutter from being flooded.

5. Yard drain

This drain is concealed and hidden amid your lawn. If collects water that may remain on your lawn and this water is channeled through in-ground pipes to a bigger gutter. They also have a mesh covering them to prevent debris like dry leaves from getting inside them.

6. Dry wells

The well should be properly covered to prevent any accidents around. This is one option to consider if you wish to store water long-term.

7. French drain

A French drain is created by digging a drainage path in your yard. It is muddy and easy to take up as a DIY project, but you can contact a professional to get the job done.

Another way of constructing a French drain is by putting a PVC pipe in the hole you’ve dug and then covering it with gravel to make it look better. You can also seal the top with some rocks or use the rocks to decorate the edges.

How To Fix Flooding Patio 

Here are 6 ways to fix flooding Patio and prevent your Patio from being flooded either by heavy rains or a major water spill. These methods are confirmed and tested to work accurately.

This is a huge step and a renovation of your entire Patio. The aim is to change the slope to be a little down to direct water towards a drain. This way, your Patio is not flooded, and when it rains heavily, it is directed elsewhere.

This job needs to be done by a professional that can alter the slope and still fix your Patio to match the rest of the surrounding area. Another way to do this is by mud jacking, which should also be done by a professional.

3. Installation of a Permeable Surface

This method requires you to seal our patio area with a material that allows water to pass through it easily. If you have a paver patio, you can remove some rows and replace them with gravel, plant grass beneath them, or use permeable concrete made of small stones. The only downside to permeable concrete is that it is rougher than the usual concrete floor.

You can also choose to use interlocks with space between them that can be filled with small gravel or some fine rocks.

4. Clogged drain

If your soil is exposed in your patio design, you should consider improving its drainage as it can help get rid of the stagnant water.

You can also plant water-loving plants that soak up enough water needed to grow. Adding minerals like limestone and gypsum also helps improve your soil drainage and water-retaining capacity.

6. Soakaways

This is another structure that can be paired with a French drain. It is a large hole filled with gravel that is used in storing water from heavy rainfall, the water from this hole can be absorbed by your soil.

It can also store water from other problem areas aside from your Patio. It is recommended that you don’t make a soakaway if you have clay soil because clay soil is not the best for drainage and water-retaining.
