The range, page by page.
23 products. Sizes and standards are the ones that could be read in the brochure. Where a table is withheld, ask for the mill sheet before you specify the grade.
Family
Fabrics
Needle-punched geotextiles for separation, filtration and drainage, and a polyester–glass fabric for asphalt overlays.
GB/T 17638-2008
Short-fiber needle-punched geotextile
Polyester or polypropylene staple, carded into a web and bonded by needle-punching. The brochure lists it for separation, filtration, drainage and reinforcement.
SpecificationGB/T 17639-2008
Filament spunbond needle-punched geotextile
Continuous polyester filament, spun into a web and needle-punched. The brochure offers a mass from 80 to 800 g/m².
SpecificationPolyester–glass paving fabric
A wet-laid sheet of glass fiber and polyester fiber, described for waterproofing and reinforcement under asphalt.
SpecificationFamily
Barriers
Composite and HDPE geomembranes, plastic waterproof sheet, and rubber waterstops for joints.
GB/T 17642-2008
Composite geomembrane
A plastic film laminated with nonwoven geotextile. One fabric and one film, or two fabrics and one film. The barrier is the film; the fabric adds strength, puncture resistance and friction.
SpecificationCJ/T 234-2006
HDPE geomembrane
Smooth or textured sheet in high-density polyethylene, made on a three-layer co-extrusion line. Thickness 0.25–3.0 mm, width up to 8 m.
SpecificationGB 50108-2008
Waterproof board
EVA sheet, and ECB sheet, for underground and tunnel waterproofing. The brochure identifies both with the plastic waterproof board in GB 50108-2008.
SpecificationRubber waterstop
An extruded rubber profile cast into concrete joints. Buried profiles and rear-mounted profiles, with or without a centre bulb, plus steel-edge, hydrophilic and flat sections.
SpecificationFamily
Reinforcement
Steel-plastic, polypropylene, polyester and glass geogrids, geocells, and extruded geonets.
JT/T 480-2002
Steel-plastic geogrid
Steel-plastic strips joined into a grid. The surface is embossed so the reinforcement can develop friction in a soil cushion.
SpecificationBiaxial polypropylene geogrid
Polypropylene sheet, extruded, punched and stretched in both directions. The brochure presents it as an interlock system for permanent loaded ground.
SpecificationUniaxial plastic geogrid
Stretched in one direction, in polypropylene or in HDPE. The brochure treats the two polymers as separate tables for walls, slopes and pavements.
SpecificationWarp-knitted polyester geogrid
High-tenacity polyester yarn, warp-knitted into a grid and coated with PVC. For soft ground under roads, railways and hydraulic works.
SpecificationFiberglass geogrid
Alkali-free glass fiber, warp-knitted and coated, for asphalt overlays and for reinforcing a rigid or semi-rigid pavement.
SpecificationGeocell
Polyethylene strips welded with ultrasound into a three-dimensional cell. Filled with local sand, gravel or soil for a load-bearing mattress or a vegetated slope.
SpecificationExtruded geonet
A diamond geonet in the CE121, CE131 and CE151 series. The brochure spends its detail on CE131 for soil and pavement, and CE151 for slopes, rivers and tunnels.
SpecificationFamily
Drainage
Tri-planar drainage nets, dimpled boards, plastic blind drains, and permeable pipes.
Tri-planar composite drainage net
An HDPE net with a stiff longitudinal core and two crossing layers that keep the geotextile out of the flow path. Geotextile is bonded to both faces.
SpecificationPlastic blind drain
A melted plastic-filament core, welded at the nodes into a three-dimensional body, and wrapped in filter fabric.
SpecificationDimpled drainage board
A studded sheet in high-impact polystyrene, with a geotextile filter on the studs. The brochure discusses the PSD10 (103) board.
SpecificationJC 937-2004
Flexible permeable pipe
A soft pipe on a steel-wire helix, with a nonwoven filter and a polyester yarn cover. The brochure cites JC 937-2004.
SpecificationRigid PE permeable pipe
A rigid HDPE pipe with a patterned wall. The upper two-thirds is perforated. The lower third is solid, so water that has entered is less likely to leak back into the ground.
SpecificationFamily
Slopes and site work
Erosion-control mat, ecological bags, self-adhesive anti-crack tape, and sonic logging pipe for piles.
Three-dimensional erosion-control mat
A loose, loofah-like polymer mat for slopes that will be vegetated. The brochure says about 90% of the volume is open for soil, sand and fine stone.
SpecificationEcological bag
A bag in polypropylene or polyester needle-punched nonwoven, for flexible vegetated slopes. The brochure describes a UV-stabilised fabric that passes water and holds soil.
SpecificationSelf-adhesive anti-crack tape
A self-adhesive strip for joints and cracks, used when asphalt is laid over concrete or over an old road. Cold applied, after the release film comes off.
SpecificationSonic logging pipe
A steel access tube cast into a bored pile so an ultrasonic probe can travel the length of the shaft. The brochure treats the joint and the layout as part of the test, not as an afterthought.
