Perforated Drainage Pipes

Our perforated drainage pipes are vital for civil drainage engineers and are a key part of our drainage solutions, drainage channels, and water management systems.

Carefully engineered, these pipes are highly effective channels for managing excess water and surface water runoff.

They are crucial in reducing flooding risks and ensuring good water distribution across various landscapes.

Design and Functionality of a Perforated Pipe

Each perforated land drainage pipe is designed to allow water to enter the pipe easily.

This design ensures that extra surface water is quickly drained away, preventing waterlogging that could harm farming, construction work, landscaping projects, or sports fields.

Versatile Applications

From handling surface water drainage to controlling underground moisture levels and improving soil quality and airflow, our perforated drainage pipes perform exceptionally well in many different uses.

Whether you're dealing with heavy rainfall on your golf courses or trying to improve soil conditions for better crop yields, these pipes offer a reliable and cost-effective solution to meet your project's specific needs.

Durable Construction

Made from high-quality materials like High-Density Polyethylene, our single-wall and twin-wall drainage pipes are built to last in various weather conditions.

Their strong design ensures they'll work well for a long time, providing lasting solutions for efficient water drainage in all kinds of projects, from big civil engineering developments to small garden drainage jobs.

Enhanced Performance with Membranes

For enhanced performance, our perforated pipes can be used with geotextile membranes in French drain systems.

This combination provides superior filtration, preventing soil particles from entering the pipe while allowing water to pass through freely.

The membrane is a barrier, enhancing the drainage system's overall efficiency and lifespan.

FAQ

Is perforated pipe good for drainage?

Yes, perforated pipe is excellent for drainage. Its design, featuring small holes or slots along its length, allows water to enter the pipe from the surrounding soil.

This makes it ideal for collecting and redirecting excess water, effectively preventing waterlogging and improving soil pipes and conditions.

Perforated pipes are widely used in various applications, including agricultural drainage, construction site dewatering, and landscape management.

How deep should you bury a perforated drain pipe?

The depth at which you should bury a perforated drain pipe depends on several factors, including the type of drainage system, local regulations, soil type, and climate. According to industry standards:

The typical depth range for land drainage applications is 600mm to 900mm (approximately 24 to 36 inches).
A minimum depth of 750mm (about 30 inches) is often sufficient for residential applications.
The overall depth range for underground drainage systems is typically between 600mm and 1.5m (approximately 24 to 60 inches).

It's important to note that these depths can vary based on:

Local authority regulations: Always consult your local water authority and Building Inspector for specific requirements.
Soil type: Different soils may require varying depths.
Frost line: In areas prone to freezing, pipes must be installed below the frost line to prevent damage.
Ground movement: Deeper installations can protect against soil movement.

For more information on this or underground drainage pipe, read our article "How deep should underground drainage be?"

What is the correct way to install a perforated drain pipe?

The correct installation of a perforated drain pipe involves several key steps:

To ensure proper water flow, excavate a trench with a slight slope (about 1 inch drop per 10 feet of length).
Line the trench with landscape fabric to prevent soil infiltration.
Add a layer of gravel at the bottom of the trench.
Place the perforated pipe in the trench with holes facing downward to prevent clogging.
Surround the pipe with more gravel to enhance drainage.
Wrap the landscape fabric over the gravel and pipe.
Backfill the trench with soil.

Ensure the pipe is properly connected to an outlet or drainage system for optimal performance. For more in-depth guide, read our how to install perforated pipes article.

Can you cover the perforated pipe with dirt?

While you can cover perforated pipe with dirt, it's not recommended to do so directly. For optimal performance and longevity of the drainage system:

First, cover the pipe with gravel or crushed stone. This allows water to enter easily and prevents soil from clogging the perforations.
Wrap the gravel and pipe in landscape fabric or a geotextile membrane. This acts as a filter, allowing water to pass through while keeping soil particles out.
After these protective layers are in place, you can cover the system with dirt or topsoil.

This method ensures the perforated drainage pipe continues to function effectively over time, maintaining good drainage without becoming clogged with soil.

SPLIT DELIVERIES

If you have ordered a mixture of goods that come both from us and direct from our manufacturing partners, you will be advised of this in your dispatch email. As the order is coming from two locations, you will receive two different deliveries. Delivery on direct items can have extended lead times and will need someone present to check and sign for the goods.

Occasionally, we don't have all items in stock at our main warehouse. If this is the case, we will endeavour to send the stock the same day from one of our other branches, in order to not delay delivery of the complete order. This may lead to a split delivery, dependant on the courier being used. We will contact you if there is going to be a delay due to this.

LABOUR AND MACHINERY

Please do not book machinery or labour until your goods have been received and checked over. Whilst every effort is made by our couriers to deliver your parcel within the stated timeframe, Professional Building Supplies cannot be held responsible for any additional costs incurred by delays outside of our control.

CHECKING AND SIGNING FOR ORDERS

SIGNED FOR POLICY – T&CS

All orders should be signed for. If you are unable to sign for your delivery, you can arrange with us for a neighbour to take delivery of your order. You can also advise us of a safe place where your order can be left, although we cannot take responsibility for any shortages or obvious damages.

Please ensure that you always check the number of packages that you are signing for. If there is an incorrect number of packages or any package appears damaged, you should note this on the signature panel and advise us so that we can rectify the issue as quickly as possible. Once goods have been signed for as being received ‘complete and in good condition’, any claims are not covered by the carrier’s insurance company.

Signing for goods as ‘unchecked’ makes any claims inadmissible, so please check the number of packages and look for any signs of any damage, noting any issues on the signature panel. Although the delivery drivers are busy, they are contractually obliged to wait whilst you check your delivery.

WHAT IF I CAN’T WAIT IN ALL DAY?

There is a ‘Notes’ section of the Basket review page where you can request for your goods to be left in a safe location – just tell us where to leave the order. Please not that we cannot take responsibility for any shortages or obvious damages if goods have not been signed for.

Please note that deliveries made by DHL (these are generally small orders with no pipe or bulky products) cannot be left in a safe location. You will be advised which carrier will be delivering your order by email at the point of dispatch.
