Many locations around the world get a lot of rain. With an average of 33 inches of rain per year, this is especially true in the U.K. where it is rare for a day to pass that it is not raining somewhere. Regardless of where you live this can lead to problems with garden and patio flooding. Water can accumulate in the ground and prevent excess runoff from being absorbed properly.

Most problems with waterlogging and flooding in most gardens tend to stem from poor landscaping and lack of ground preparation to help rainwater drain away, this is where the use of eco-friendly plastic grids can come in handy.

Headaches You Don’t Want To Deal With

One of the biggest problems that can occur from poor drainage is the increased risk of flooding which can damage not only your garden but also your home. Excessively wet soil that does not dry up can cause problems inside the home such as flooding, water seeping into the brickwork, increased risk of mildew and mold, and weakening of cement and mortar.

In the garden, it can lead to boggy or marshy conditions that prevent plants and grass from surviving, soil full of bad bacteria, foul-smelling odors, and a decline of the soil. It can also make the ground very soft causing heavier items such as sheds and patios to begin to sink or tilt, and brick walls to warp and fall down.

 Create Drainage Channels

In order to prevent these types of things happening you will need to provide a way for water to drain away from the ground. The first step to take is to provide drainage channels that are dug around 4 feet underground and filled with a coarse material such as gravel, pea shingle, or slate chips.

The channels should lead away from any areas that contain structures and where the water can easily flow out off. Once the channels have been filled the soil should be backfilled and it is always a good idea to mix gravel into the soil layer too.

A Base For Support

Next, you want to provide a supportive base for the grass or patio by employing the use of some eco-friendly plastic grids that allow water to escape easily. Eco-friendly plastic grids consist of an open cell structure that allows rainwater to pass through with ease and also helps keep grass, gravel and patios level and in place.

The whole idea is to provide a stable and solid base that does not prevent excess water from permeating into the ground yet remains an eco-friendly and cost effective option.

 

Defeating Clay-Rich Soils

Flooding tends to occur most commonly in clay-rich soils where the fine particles clump together and prevent water molecules from passing through. This can be problematic in areas where there is a high proportion of clay based soil.

To combat this can prove to be a big job and usually involves having the garden dug up and a medium such as gravel or peat mixed into the soil before putting it back. It is during this stage that it is a good idea for the drainage channels to be dug or to have plastic drainage pipes installed underground.

It is important to ensure that you have the soil compacted after as if you fail to do this then it will slowly drop over time leading to uneven surfaces. Using plastic grids this can help retain a level surface as the interlocking grids provided a single, stable layer.

Grass roots can create a thick layer that can delay the drainage of water, to help deal with them you can use a garden fork to aerate the ground and create micro holes that will allow the water to escape.

Deal With The Sources Of Water

Some of the main sources of excess water are roofs, roads and driveways. To reduce the effects of flooding these areas should be taken care of. If a roof is the main cause of water collecting in the garden then it is a good idea to have drains fitted to the roof to divert the water away into the drainage system.

Roads and driveways should already have drains installed, but if this is not the case you could have a small brick wall built to prevent water entering the garden. As most flooding problems are caused by impermeable materials such as cement and tar it is a good idea to consider better options such as gravel driveways and patios with large enough spacing to allow water to drain away.

A gravel driveway is a perfect solution for dealing with areas that flood as the gravel will allow the water to pass through freely and into the ground below. If you are installing or thinking of installing a gravel driveway then you need to consider using plastic grids that lock together to be placed beneath the surface.

The interlocking units prevent the gravel from moving and help stop potholes or uneven distribution of the gravel. The specially designed grids also allow water to pass through them and can support up to 420 tons of compression per square meter.

You could opt not to use grids but they are the better option for gravel driveways due to being eco-friendly, water permeable, strong and durable and cost effective.

Without some form of barrier beneath the gravel, you will experience shifts in the stones leading to them becoming dispersed, the potential of them being absorbed by the ground beneath and less drainage due to compression into the soil below.

Keep Patios Flood-Free

Grids are also an excellent option when installing a patio as they not only provide a solid and level surface for the patio slabs but also provide a gap between the slabs and the soil beneath them so that water can drain away quickly.

If water is left standing on a patio it can lead to a build-up of algae which can not only become very slippery making the patio a safety hazard but also cause damage to the surface of the slabs over time.

When laying a patio DO NOT fill the gaps between the slabs with cement or grout, use fine pea shingle and have it compacted in the spaces so that it acts to keep the slabs in place while allowing water an escape route.

Water will always follow the point of gravity, meaning that any sloping areas of uneven surfaces will attract the water making it harder for it to drain away in those parts.

 

Save Your Garden 

A garden that floods is a garden that is difficult to enjoy, especially if it is always an uphill battle to keep the ground dry and your plants alive. You could take advantage of planting thirsty trees such as Willow, Pumpkin Ash or River Birch which all soak up huge quantities of water.

Plants that help are Hibiscus, Petunias and many tropical plants such as Banana and Canna which absorb a lot of water quickly. Preventing flooding normally takes a multifaceted approach and relies on some hard groundwork for maximum benefits.

Once the soil is improved and you take advantage of plastic grids beneath the surface level and provide adequate drainage you will never have to worry about flooding in the garden again. It can be a daunting and frustrating process working out how to regain control over your lawn and patio and once you know where to begin you can start to improve upon it.

Remember to take advantage of nature’s sponges by utilizing water thirsty plants and trees and to add mulch, shingle or loam to your soil to help break up any clay contained in it.

Digging drainage channels is a great idea if you have the time and energy to do so as they help move the water away rather than leaving it to sit in the soil. Using eco-friendly plastic grids can allow for easy draining, and provide a secure and hardy base for grass, shingles, pebbles, gravel and patio tiles.

The design of the grids allows water to escape quickly and helps prevent surface build up. At the same time grids keep the surface secure preventing potholes and dips that allow water to sit for longer.

A well looked after the garden that has been planned out to prevent flooding will provide you with a gorgeous space where you and your family can create lasting memories for years to come. If you have been suffering from a waterlogged lawn or patio, try these steps to remedy the problem or prevent it before it starts!
