How we can help?<\/h2>\n<\/div>
\n

We work with our partners to streamline project plans that don\u2019t just deliver on product perfection, but also delivers on time and budget \u2013 crucial to success in a highly competitive market where every day and every dollar counts.<\/p>\n<\/div>\n

<\/div>\n
\n
\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhat Material Is Cheaper PE or HDPE<\/a>\n<\/div>\n
\n
\n

The PE or polyester Rock Bag Filter Units would be considered our standard fibre (generation 1.0) offering the best value. The lifecycle remains extensive as we only use virgin polyester material. HDPE is second generation material which offers further life cycle, again virgin polyester in high density configuration for high demand and sensitive environments.<\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhere Abouts Do We Ship Products<\/a>\n<\/div>\n
\n
\n

We have the logistical experience and capabilities to ship material to any location in the world. From small quantities to 40′ containers, no job is to small or to far.<\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhere Do We Buy Rock Bag Filter Units<\/a>\n<\/div>\n
\n
\n

There is a range of clients who support and use Rock Bag Filter Units from distribution partners, government agencies, tier 1 contractors for civil and marine projects, installers, engineers, environmental specialists.<\/p>\n

Call or email us today regarding your interest and upcoming project.<\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nCould There Be Any Discounts?<\/a>\n<\/div>\n

\n
\n\n<\/span>\n<\/span>\n<\/span>\nDo You Give a Warranty?<\/a>\n<\/div>\n
\n
\n

Yes – Our products are covered under warranty. We take quality very seriously with interval checks such as examination of raw fibre through to strength and tensile tests post manufacturing to ensure our rock bags are fit for purpose, safe, reliable and long lasting.<\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhat sizes do Rock Bag Filter Units come in ? <\/a>\n<\/div>\n
\n
\n

Rock Bag Filter Units in a standard offer come in 1, 2 , 4 , 6 and 8 t configurations in either polyethylene (PE) or High Density Polyethelene (HDPE). However, Rock Bag Filter Units can be supllied up to 12 t, and dependant on the quantity other sizes are available.<\/p>\n\n\n\n\n\n\n\n\n\n

\n\n<\/span>\n<\/span>\n<\/span>\n What tests do Rock Bag Filter Units go through? <\/a>\n<\/div>\n
\n
\n

Rock Bag Filter Units, as with all Geosynthetics used in the built environment are subject to a series of internationally recognised tests. Rock Bag Filter Units are not only subjected to these tests but as a apart of our internal quality control measures Rock Bag Filter Units are subjected to a suspension test where the bags are filled to capacity and suspended for 30 minutes and inspected for degradation. The tests are done in house under the supervision of a certified testing authority, further Rock Bag Filter Units only use stamped load rated lift rings ensuring operator safety.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\n\n<\/span>\n<\/span>\n<\/span>\nHow are Rock Bag Filters made?<\/a>\n<\/div>\n
\n
\n

The Rock Bag Filter Unit manufacturing process utilises “Warp” knits exclusively manufactured on a Chain Loom, with each warp controlled by a seperate needle. Warp Knits produce run resistant, closer, flatter and less elastic knits. Common Warp Knits are Tricot, Milanese and Raschel. Project Material are Joint Venture partners with the manufacturer, producing bags to strict specifications utilising “Raschel Warp Knits”. Our joint venture enables the complete chain of custody and Quality Management Systems.<\/p>\n

Rock Bag Filter Units are a\u00a0Rock,Bag,Composite; <\/b>creating a single mass by encapsulating smaller rocks into a high strength synthetic bag. The Rock Bag Filter Unit keeps the rock under tension substantially restricting movement of the media within the bag while maintaining flexibility during placement. When placed, Rock Bag Filter Units tightly mould to their environment, with subsequent placements tightly moulding and interlocking with the previous. . Initial settling of the bag will occur which only serves to consolidate the entire structure.<\/p>\n

For the composite to work correctly, Rock Bag Filter Units are filled by volume not weight. The term “ton” to describe the size is merely a identifier that on average the finished product\u00a0 will be within that weight range . When filled correctly , Rock Bag Filter Units will not allow rocks to move liberally, though mobilisation of some fines will migrate to the centre without without effecting performance.
\nTo-date scale modelling has failed to replicate the composite attributes of Rock Bag Filter Units.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
