Laylite is a range of culvert and flume products produced right here in New Zealand by plastic manufacturer Alto, who focus on developing and supplying products that are sustainable. The Laylite range has many uses including water management and reticulation in agricultural, civil and forestry applications.
Hydraulic Design
Engineered for gravity flow systems, the turbulent flow created by the pipes internal corrugations ensures self-cleansing. In partially filled pipelines (usual circumstances) the corrugated interior also helps control discharge velocities, reducing the potential for erosion at pipes outlet and may eliminate the need for expensive energy dissipaters and drop structure manholes.
For non-pressure gravity flow under conditions of constant slope and uniform channel cross-section (as often is the case where the pipes are only partially filled), the Manning equation is commonly used.
Light Weight
The light weight of Laylite ensures it’s easier to transport and fast to install using minimum staff and lifting equipment. For example a 6.6 meter length of Laylite pipe weighs only 63kg’s.
Versatile
Laylite Culvert is available in 400mm and 600mm diameters, in short lengths with bayonet interlocking sockets or welded lengths up to 6.6 metres, to suit a wide range of applications.
Laylite Flume is easily and securely coupled by means of self-tapping stainless steel screws, over interlocked flume corrugation.
Impact Resistance
Laylite takes the knocks and bumps of handling, moving and installation with ease. The combination of non-brittle HDPE and its unique corrugated profile makes Laylite capable of sustaining impact in both warm weather usage and cold weather installations.
UV Resistance
Laylite pipe contains a minimum of 2% carbon black additive to protect the product from ultraviolet light. This gives Laylite pipe maximum weather resistance in applications where continuous exposure to the elements is expected.
Abrasion Resistance
Abrasion is the wearing away of a pipe material surface, caused by an abrasive bed load (gravel, rock or sharp stones) being carried by the flow.
Tests indicate that HDPE pipe is highly resistant to abrasion, giving it a significant advantage over other pipe materials in both acidic and abrasive environments.
Durable
Manufactured from 100% recycled HDPE Laylite can take the knocks. Laylite is a sturdy drainage piping system designed to resist weather conditions and built to last.
Strong
The optimum 60º corrugated profile provides Laylite with its inherent pipe stiffness while still allowing longitudinal flexibility. So unlike twin wall plastic pipes or uPVC plastic pipes that are longitudinal stiff, when bedrock or other obstructions are encountered in the trench excavation, Laylite can be “snaked” around these obstructions minimizing installation labour.
Flexible
Unlike rigid pipes, Laylite Culvert can be snaked around obstructions in the trench, negating the need for costly fittings. Laylite Flume’s 10° maximum longitudinal flex allows it to meet ground contours for ease of installation.
Compatible
Laylite Flume is easily connected to a wide range of structures and discharge pipes manufactured from alternative materials.
Suitable
Laylite Culvert is available in a choice of short lengths for easy transport to and around the farm. The corrugated channel helps control discharge velocities, reducing potential scouring at the Laylite Flume’s end.
Efficient
Light-weight HDPE construction makes for fast and safe installation. Being made from polyethylene, a much lighter material than concrete or galvanised metal, ensures Laylite is easier to transport.
