In order to remain clean and prevent standing water, In-ground pools require proper deck drainage. Proper drainage provides splash and rainwater to go and also prevents entering excess debris into your pool. To keep your patio in good condition, whether you’re having a new pool installed or a new deck around the existing one, proper deck drainage guidelines should be followed:-
Why Is Drainage Important?
A small amount of water splashed out on the pool deck seems like it will evaporate and dry. In some cases, this may happen, but splashing is not the only reason for water on a deck, and sometimes a poorly designed patio can be overwhelming due to splashing.
Puddling, pool water overwhelming and outside water entering into the pool are the main problems of poor deck drainage. Puddling can cause stains, ugly molds and make the deck slippery. Raised planter box and water coming from a downspout are likely to carry dirt, bacteria and debris into the pool.
Many times, pool water enters into the landscaping from the patio. When the weather is hot and dry, and the soil is desiccated, this may work fine, but it doesn’t work well in wet weather and saturated soil. The excess water may wash away the soil, drown plants, and allow dirty water to enter your pool.
Which Direction Should A Patio Slope Be?
The slope of your pool deck should be far away in order to prevent draining of dirty water into your pool, i.e., water contaminated with dirt and debris and, of course, the splashed out water both. Make sure that the slope of the deck is away from the pool’s edge to prevent the draining of dirty water into your clean, nice pool.
Approximately the slope of the deck should be a quarter of an inch per foot. This means that for every four feet of width, a proper pool deck will be about an inch of fall. Some decks slope down in one direction, whereas others have multiple or valleys in different directions for drainage.
Types Of Drainage Systems:-
There are many options for deck drainage. The common ones are listed below:-
There are long metal grates that cover a structure like a trench, and the water flows into them and then afterward goes away from the patio. This system is ideal for patios that run against the house and also for valley patios to divert water to a center point rather than against a house.
They are best for a deck that are free-formed and can be put in small places. They are similar to strip drains but have multiple and round drains that are connected to each other through piping where water collects naturally; you can place a bit of drains all through the pool deck.
Gravel filled pits which have drain pipes below are called French drains. They are used typically when the deck ends in the landscaping, but for natural drainage when the volume of running water is too much into the landscaping. These drains fix nicely near your pool deck to the natural landscaping.
Signs To Redo Your Deck’s Drainage System:- An important part of owning an inground swimming pool is deck drainage. Most people have a drainage system, so the question arises as to when it should be remodeled or replaced? You can resolve some problems without replacing the system, while others with a new set of equipment can be remedied.
Standing Water:- Lack of drainage is the number one thing to look out for. It’s time to take some action if there is standing water anywhere, which shouldn’t be. As mentioned earlier, standing water causes debris, mold, and bacteria.
No Right Location Draining:- Draining is another problem that we often face, but not to the right location. Excess water of your pool deck should drain off into an area with soil and pebbles landscaping that can absorb well or a drain system.
Visible Damage:- If the drain system is cracking, rusting, or breaking, it may be replaced. It’s pretty easy to spot these impairments and to make sure that everything looks good, you should check once or twice per year on them.
Problems With Landscaping:- You may need to inspect your pool drainage system if you have over watering problems in your nearby landscaping and also ensure that too much water is not dumping into your soft scape. It is hard to determine the problems in a drainage system in some cases because spillover may be intermittent from the pool depending on use. So in such cases, when people are using the pool try to watch where the water drains.
Drain System Fixing:- The first thing to consider is to see whether the drainage system is inadequate or is malfunctioning. To create the needed water pressure, using a pump to flush out a clogged drainage system with piping is necessary. A drainage system that provides water a way to run off into the landscaping requires some more equipment for formal drainage to control the water flow.
In some cases, the piped drainage system may get clogged with concrete that cannot be washed out. Consider this as a potential issue if your drain system cannot be flushed clean or is sluggish. It may be necessary to inspect the entire drainage system for issues like broken equipment if it is not flushed properly.
You might need to install additional drains if you find water going in the direction you don’t want. The problem can be solved by putting a new drain between ending up and the source of water.
However, some construction work may be required if the present piped drainage system is in place. Go through our guide on pool coping in case you are planning a major pool deck work.
