Draining Water from Under a House: When the weather gets bad and there is a huge amount of rainfall, your property can suffer with an overflow of rainwater. However, this excess of water does not need to drown your lawn or start flooding your property. You can avoid these serious problems with the help of a perforated drain pipe. Having a perforated pipe underneath your property will help drain excess water away from your home, leaving the area dry and avoiding costly problems like rot and water damage. There are a number of uses for perforated pipes and we have listed some of the most common below so that you can get an idea of what these systems can do. If you're installing a half-perforated pipe, such as half perforated twinwall, this is where the problem comes into question; whether the perforations are best facing upwards or downwards? A perforated drain pipe is designed in such a way that it allows water to enter or exit through a number or small holes along the pipe. This allows excess groundwater to be drained from your property and released elsewhere. Below are some of the most common uses of perforated drain pipes. Common Uses for Perforated Drain Pipes

The CivilWeb French Drain Design spreadsheet includes analysis modules to complete both these perforated pipe drainage system calculations to ensure that the french drain is fit for purpose. The spreadsheet completes the calculations following the SUDS manual procedure as detailed below. Perforated Pipe Design - Perforations Filling the trench with gravel will prevent the soil from sinking and clogging up the pipe when it rains. Gravel helps to keep everything in place, ensuring your perforated pipe lasts and lasts. It is important that the trench is filled with gravel up to 2 inches so that the pipe can fit comfortably on top. Step Five: Laying the Perforated Pipe Contrary to popular opinion, the most effective method is to have the holes facing down. Why do the perforations go downwards? We start by digging a trench that is twice as wide as the drainage pipe and deep enough to install the pipe below the frost line. For larger installations, we can carry out more extensive excavations if this is necessary.

Perforated Pipes and Landscapes: A well designed garden landscape can transform your outdoor space, but it is important to protect your garden from changing weather conditions. Using perforated pipes discreetly in your garden landscape can help to absorb excessive rainwater, draining it away from your garden and property. By installing perforated pipes under the ground, excess water can be drained away so that your garden landscape is not at risk of damage. When a perforated drain pipe is installed by our professional team, it provides an effective solution to any problems you are experiencing with excessive groundwater near your property. Installing a perforated drain pipe can be done in six easy steps. Step One: Digging the TrenchThe pipe should be surrounded by gravel in a trench where water moves through the ground, passes through the gaps in the gravel, and starts to fill the trench surrounding the pipe. As this happens the water will percolate into the pipe through the holes and flow out of the pipe when its installed with a fall. Both land drain and twinwall are available with or without perforations, and these perforations are what allows the water to enter the pipe and drain the ground surrounding the pipe. If you choose a perforated pipe for your project you are likely looking to drain surface water from soil or grassy area.

Land drain, often known as French Drain, is the name given to flexible coiled pipes which are laid underground to alleviate excess surface water. They are corrugated and can typically flex 90 degrees per 1m, and come in either perforated or unperforated coils, available from JDP in sizes varying from 60mm-160mm in 25m, 50m or 100m lengths. How do land drain pipes work?Before our team install your perforated drain pipe, we start by choosing the best location for it. We want your perforated pipe to work effectively and that means locating it in the most useful place. Often, the best place for these pipes is under your property or in your garden. So, once we have located the best place, we commence the installation. Unperforated land drain is used for distributing surface water, these pipes have no holes; they are used to redirect water to a watercourse such as a stream, river, water tank or soakaway. Land drain should only be used for surface water drainage, never for foul water. Where should I use land drainage? Typically, land drainage is arranged in a herringbone style with one central pipe and several branches coming out of this; this ensures the area is drained efficiently and maximises the effectiveness of the land drain pipes.

This is the area of each orifice. Areas given in mm 2 can be converted to m 2 by multiplying by 10 Although you would think that having the holes at the top would mean the water could fall into the perforations, as it flows through the ground, this doesn't offer the best performance.Land drain can be used in a variation of different applications from agriculture to construction, for different purposes. Perforated land drain is typically used to drain fields to improve soil quality and can also be used in sports fields and to drain domestic gardens.
