What is ACO channel drainage and where is it used?

Channel drainage (often referred to generically as "ACO drainage" due to the brand's popularity) is a system designed to effectively collect and manage surface water. It consists of a long, narrow trough set slightly below ground level, covered by a protective grating. These drains are essential for preventing standing water and are commonly installed at the edge of patios, across block-paved driveways, or at the threshold of garages to direct rainwater away from your property.

What size underground drainage pipes do I need for my property?

For standard residential plots, underground drainage pipes and fittings are typically 110mm in diameter. These 110mm pipes are designed to handle gravity-fed wastewater and sewage from domestic properties. For larger commercial sites or systems serving multiple properties, you would step up to a 160mm pipe diameter to accommodate the increased flow volume.

What is a recessed manhole?

A recessed manhole, is a manhole which is sunk down and after installation runs flush with the finished surface. This design allows you to fill the tray with the exact same material you are using for the surrounding area, such as block paving, concrete, or paving slabs. Easiest way to seamlessly hide underground drainage for your patio.

What is the purpose of an inspection chamber or manhole?

An inspection chamber (accessed via the manhole cover at ground level) provides engineers with a safe, temporary access point to the underground drainage system. These chambers are strategically placed where pipes change direction or join together. If a blockage occurs, the manhole cover can be lifted, allowing specialists to inspect the pipes, clear debris, and carry out essential repairs without having to dig up your patio or driveway.

What is a geotextile and why is it used in drainage?

A geotextile is a highly durable, permeable synthetic fabric used extensively in civil engineering and landscaping. Beyond filtration, geotextiles are used for "separation" and "stabilisation" vital for maintaining a strong, stable foundation underneath driveways, patio, paths and much more.
