pet 200g recycled geotextile fabric

pet 200g recycled geotextile fabric Introduction:

pet 200g recycled geotextile fabric is widely known as earthwork material and industry fabric, used in the areas of railway, highway, water conservancy, dam, tunnel, subway, environment protection and so on.

pet 200g recycled geotextile fabric Feature:

1.using geotextile good air permeability and permeability,make water flow through,thus effectively interception of soil erosion.
2.geotextile prevent the lower sand,soil and concrete between mixed
3.it has good performance,it can guide water soil formed within the drainage channels,soil structure in excess liquid and gas discharge
4.with polypropylene fiber or polyster as material,geotextile have high strength,andti-aging,anti-acid and anti-alkali,not eaten by moth,oxidation

pet 200g recycled geotextile fabric construction step:

Step 1

Form the path tray

excavate the tray as for an aggregate path, with the exception that the depth does not need to reach a solid base
form a base that is level and even for laying the geotextile
remove any protruding bog wood, stone or boulders to prevent distortion or puncturing of the matting
if the peat is very wet, or has no vegetative content, form the tray depth and sides with good size turfs, after laying matting

Step 2

Lay the geotextile matting

line the path tray with the geotextile matting, cutting it to the required width
to take up curves and bends in the path either fold the matting or cut it to suitable lengths, allowing an overlap of at least 300mm
secure folds or overlaps with larger aggregate stone to prevent them protruding up through the path material
if the matting is laid wider than the path place large turves, or boulders, over it to secure and form the required path tray width
to prevent aggregate migration into the peat, or peat into the path structure, the matting may be folded halfway up the tray sides
to prevent subsequent exposure at the path edges tuck folded up matting back from the path tray and dig under the surrounding vegetation, or place turfs over the top

Step 3

Lay the geogrid

where required, lay the geogrid over the matting, cut to the required path width, and for bends in the path alignment; as with the matting joins should overlap by 300mm
where there is an excess on either side, due to the variable path width, it should be dug into the tray edges, or, if the matting is folded up, cut to the exact size
the geogrid should not curve up the tray sides; it is important that no geogrid edges are left exposed after the surface has been laid and compacted

Step 4

Incorporate drainage features

construct drainage features as for an aggregate path, with the exception that geotextile should be laid to continue into construction trenches
for ease of laying, and to provide additional strength, cut the geotextile to allow a full overlap across the drainage trench width

Step 5

Construct the aggregate path.

take care to prevent any puncturing of the matting when laying and compacting the lower layer of base, or sub-base material
care is also required if moving aggregate along the prepared path tray with a powered track barrow; minimise the number of movements as far as possible

Step 6

Edge finishing

make sure that any turfs already laid are effective in covering the geotextile and containing the aggregate
the path edges may require further turfing and landscaping, to define the line and ‘soften’ the appearance
use excess turf and spoil from the tray excavation to re-instate any eroded or damaged ground, and for in-filling any borrow pits (see Introduction to Restoration Techniques)
