Perforated pipes are installed to collect excess water from the soil and drain it directly down to the roots of plants or crops—this helps to keep the irrigation land healthy without flooding the field. Perforated pipes can be PVC, cement, clay, and iron. The most popular ones are PVC pipes, which are lightweight and flexible. This article discusses the basic features and applications of perforated pipes used in construction. Features of Perforated Pipes Used in Construction Manufactured from HDPE, these weatherproof, lightweight and strong pipes feature a smooth internal surface for an increased flow rate, while the outer surface has a ribbed structure for a high compressive strength.

Perforated pipes are no longer a British Standard product. The pipes are drilled whilst wet and the semi-dry nature of the concrete used in the manufacturing process leads to spalling on the inner and outer surfaces around the holes. This is cosmetic only and does not affect the integrity of the pipes for land drainage use.

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.

Although coiled land drain pipes are by their very nature flexible so bends are not required, we do sell joiners for connecting two lengths of pipe together. These are loose-fit push fit joints – no seals are required as unlike foul or surface water drainage there is no requirement for joints to be watertight in land drainage installations. The main characteristic of a perforated pipe is to take in water from the wet ground through the perforations and allow the ground to stay dry. Hence, the two functions of a perforated pipe are the collection and conveyance of water.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? Twinwall pipes are used in surface water drainage systems to drain excess water in a range of applications such as agricultural, highways, railways and airports. These pipes can also be used to drain excess surface or stormwater in domestic settings such as garden drainage. Delivery to non-Industrial Scotland, Northern Ireland, and CH, LL, and CA postcodes can sometimes take slightly longer, although this is dependent upon the exact location.
