5. Installation Steps of HDPE Pond Liner in Canada
The laying and welding construction of geomembrane pond liner is a key link in the entire anti-seepage project. The construction quality of the geomembrane anti-seepage layer determines the success or failure of the entire project. Every process and link must can organize and construct carefully during construction. The following are the main steps for geomembrane pond liner installation in Canada.
(1) Geomembrane installation preparation
Open the package to check the HDPE geomembrane pond liner appearance. Record and repair any mechanical damage, production trauma, holes, breakage and other defects found.
The geomembrane construction in the previous process complies with the design and specifications. The geomembrane construction will start after passing the acceptance inspection.
Cut and ships geomembrane pond liner. Measure the actual terrain, record the actural dimensions in detail. Cut according to the plan. Transport it to the corresponding location on the construction site.
(2) Equipment requirements
Clean and test the geomembrane welding machine must be before each shift or daily work.
(3) Laying requirements for special parts
When laying pond liner Canada at the foot of the slope. The base surface should be flat and smooth when turning intersection. The geomembrane can not suspend in the air.
It is necessary to take measures to ensure the membrane pond liners adhere tightly at slope intersections.
The foot of the slope, where the side slope connects to the bottom of the site, requires special treatment. It is necessary to lay the slope HDPE geomembrane along the slope for a distance of 500mm from the slope toe. You can perform a welding operation to connect it to the HDPE pond liner at the bottom of the site.
(4) Foundation preparation and leveling.
Before laying the HDPE geomembrane, it is important for the personnel to inspect the base layer. They should properly compact and level the foundation for installation. Within a vertical depth of 25mm, they must ensure the absence of any debris that could potentially damage the HDPE geomembrane. They should actively eliminate sharp objects or potential hazards that may affect the integrity of the geomembrane pond liner items.
Backfill soil degree is important when laying the HDPE geomembrane pond liner on the backfill soil foundation. The foundation laid should be free of seepage, silt, stagnant water, organic residues and harmful substances that may cause environmental pollution. The corners of the base should be smooth. Under normal circumstances, the arc radius should not be less than 500mm.
(5) Geomembrane expansion and positioning
Carefully unroll and position the geomembrane roll to ensure adequate coverage and allow for overlapping seams. You should maintain a natural overlap for welding.
Temporarily compress the geomembrane pond liner in the anchoring trench using sandbags. After welding and adjusting the geomembrane, use rammed earth for permanent anchoring. Leave a non-anchored area of 2m on both sides for subsequent welding.
Carry out rammed earth anchoring and geomembrane pond liner welding in a crisscross manner, avoiding overlapping. Avoid immediate anchoring of the newly laid geomembrane pond liner, but instead anchor it after making appropriate adjustments.
Summary
HDPE geomembrane pond liner provides impermeable lining systems in various civil engineering applications, including landfill projects. The main raw materials used are high-density polyethylene (HDPE) and medium-density polyethylene (MDPE). There are two types of geomembrane liners: smooth and rough.
HDPE geomembrane liners are ideal and cost effective material in solid waste landfills as part of the landfill base barrier system. Geomembran pond liners are combined with a gravel leachate drainage layer, a protective layer, and either a geosynthetic clay liner or a compacted clay liner to create a composite liner. The composite liner acts as the primary barrier against leachate migration to surface or groundwater. Recent studies have focused on the prevention of fluid and gas leakage from composite liners.
HDPE geomembrane pond liner offers impermeability, high chemical resistance, exceptional stress cracking capability, low permeability, excellent UV resistance. As a result, it is widely used as an anti-seepage material for pool bottoms and covers. Its applications span across landfill projects, biogas digester projects, sludge and sewage treatment facilities, and animal manure evaporation ponds.
