The pipe is designed to collect and carry away excess ground water, while the filter sleeve acts as a protective layer to prevent sand and silt particles from clogging the pipe perforations. By trapping larger particles, the fabric sleeve maintains the permeability of the surrounding backfill, offering a cost-effective alternative to traditional filter materials. The kit is lightweight and the sleeve can be easily installed by one person for efficient drainage management.

This 80mm land drainage kit is ideal for homeowners, landscapers, and contractors looking to manage excess surface water or prevent boggy garden conditions. The primary benefit is the combination of a high-flow perforated pipe with a pre-applied filter sleeve, which significantly reduces the risk of clogs caused by sand and silt. While the kit provides a highly efficient drainage solution, it requires proper trench excavation and the use of suitable backfill aggregate to ensure long-term functionality.

FAQs
Can this pipe be used for driveway drainage?
Yes, but it must be buried at a sufficient depth and bedded in appropriate drainage stone to protect it from the weight of vehicles.
Do I need to wrap the pipe in additional geotextile fabric?
The kit already includes a filter sleeve. Additional wrapping is usually unnecessary unless you are dealing with extremely fine, silty soil conditions.
What is the recommended trench depth?
Depth varies based on local soil conditions, but 450mm to 600mm is standard for residential garden drainage.
Can the pipe be joined?
Yes, standard 80mm drainage couplings can be used to connect multiple lengths of pipe.
Is the filter sleeve removable?
The sleeve is designed to stay on the pipe to maintain its protective function against silt.
Troubleshooting
Slow water drainage
Check the outlet for blockages or ensure that the trench gradient is sufficient to move water toward the exit point.
Pipe appears flattened or crushed
Check that the backfill used consists of clean stone rather than heavy clay or sharp debris, which can damage the pipe structure.
Pros and Cons
Pros
Prevents internal pipe blockages effectively
Lightweight and easy to maneuver in narrow trenches
Reduces the need for bulky traditional filter materials
Suitable for DIY landscaping projects
Maintains drainage system permeability over time
Cons
Requires manual trench digging
Not intended for high-pressure or pressurized water lines
Must be installed with specific backfill to avoid pipe crushing
Limited length of 25 meters per unit
Setup, Compatibility & Care
Setup:
Excavate a trench with a slight downward gradient (fall) toward the discharge point.
Line the base of the trench with a layer of clean gravel.
Unroll the pipe into the trench, ensuring the filter sleeve is intact.
Backfill over the pipe using clean, washed drainage stone to allow water to permeate freely.
Care & Compatibility:
Ensure the pipe is not exposed to extreme crushing forces (e.g., heavy traffic) without proper structural bedding.
Periodically inspect the discharge outlet to ensure water is flowing freely.
Avoid using fine sand as a backfill material, as this can migrate and inhibit the effectiveness of the filter sleeve.
