The ideal slope for a plastic lined dam is a 3:1 gradient, however if design constraints require steeper gradients, installation can still be achieved, although additional safety requirements would need to be considered. Shandong Tianhai can supply ladders welded to the liner surface, alternatively you can opt for one of the options below, and soil cover the top perimetre of the dam, allowing maximum safety and aesthetics. In preparation of the dam surface (sub grade) ready for the liner installation, some earth works must be completed.This should bring the sub grade to a level that is a dry, smooth, firm and unyielding foundation, without abrupt elevation changes, voids, cracks, or standing water, free from vegetation, sharp edged rocks, stones, sticks, construction debris and other foreign debris. It is recommended to have the sub grade flat drum rolled just prior to the liner installation.

How to Stop Tree Roots. Installing a root barrier around a tree is a landscape control that helps stop the roots from damaging sidewalks, or other landscape areas. Take the time to plan your landscape before planting so you can place a barrier into the soil early in the life of the tree. This will force the roots deeper, instead of having to cut through large, mature roots that may cause damage or death to the tree. Contact a tree professional before attempting to stop mature tree roots that are close to the soil surface.

HDPE geomembranes provide an impermeable barrier against solids and liquids. They exhibit excellent chemical and UV resistance. They used as the liner. (different thickness of distinction, different thickness and different price). production capacity: thickness:0.1 mm -3 mm, width: 1-8 meters. It is suitable for seepage control in special industries, and is widely used for aquaculture, seepage control, reservoirs or sewage treatment ponds.

Geomembrane is the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications. is made from polyethylene resins materials by blow molding process.According to the different raw materials, Geomembrane can be divided into HDPE geomembrane,LDPE Geomembrane, EVA Geomembrane and PVC Geomembrane,etc.

HDPE has excellent physical property. Such as temperature adaptability, property of welding, bearing climate, anti-erosion,anti-crack and anti-puncture.As the leakage material,therefore Particularly suitable for the construction of underground,mining,landfill,sewage or dregs disposal.

Tinhy flat surface HDPE Geomembrane is produced from high-grade white color hdpe geomembrane resin produced by foreign and domestic large petrochemical enterprises by three-layer pressing and plastic formation technology and double layer pressing and rolling technology. The company is the only enterprise that uses the two technologies to produce Geomembrane in the same industry. The company has plastic formation experience for more than twenty years, makes close cooperation with earthwork builder, makes continuous innovation, seeks perfection, and makes great efforts in providing the most reliable products to the customers.

The seam area shall be clean and dry, free of mud, moisture, dust, dirt, sand or debris and seam panels are overlapped properly for fusion welding. Seam surface area shall be abraded or grinded to rid of surface oxidation and tack weld for extrusion welding. Grinding is performed parallel to the seam and grinding marks shall not extend more than quarter inch outside the weld bead area. The Welding Technician shall ensure that wrinkles or fishmouths are minimized. During seaming, visual inspection and constant hand peel testing is practiced.

For all types of welding, the Installer Site Manager shall verify that the welding personnel are attentive and act professionally and all equipments are well maintained and functioning properly. Welding Technician must purge the Extruder machine of heat degraded extrudate for at least one minute prior to use. The surfaces to be welded are well abraded and clean.

Geomembrane liners are also used as floating covers or cappings onto wastes lagoons or sludge pits to reduce air pollution, foul smell and to control flies, rodents and pests. HDPE geomembrane floating covers may be utilized in tandem with a CDM biogas digester or methane gas collection facility to co-generate electricity or to flare.

The Application of HDPE geomembrane

1) Environmental protection sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .
2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).
3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).
4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).
5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).
6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.) .
