HDPE Membrane Installation Procedures
Using and installing HDPE waterproofing membrane is straightforward and convenient. Below is a standard construction process.
- Pre-installation Site Preparation: Begin by thoroughly cleaning the construction area, and removing sharp objects and debris to maintain a smooth foundation.
- Precise Measurement for Cutting: Measure the length and width of the HDPE liner sheet accurately, ensuring precise cutting tailored to project requirements. Confirm comprehensive coverage of the targeted project area.
- Laying and Wrinkle Avoidance: Lay the cut HDPE waterproofing sheet in the designated area to prevent wrinkles.
- Seam Welding for Oversized Areas: In cases where the construction area exceeds the width of the HDPE membrane sheet, seam welding becomes necessary. Utilize a dedicated welding machine for seam processing to ensure optimal impermeability.
- Secure Fixation with Strips and Nails: Employ fixed strips, nails, etc., to secure the edges and joints of the HDPE geo membrane. Ensure the HDPE impermeable liner remains stable and doesn’t shift during use.
Precautions for Installation of High Density Polyethylene Liner
While the construction of high-density polyethylene HDPE liners is relatively simple, attention to the following considerations is crucial during installation. Here are specific precautions for HDPE impermeable membrane installation:
- Temperature Requirements:
Ensure a temperature above 5℃.
Tighten the geomembrane at low temperatures and loosen it at high temperatures.
Avoid construction during strong winds, rain, or snow. - Test Welding:
Perform on-site test welding at the beginning of the welding process.
The overlap width of the sample should be no less than 10cm.
Conduct on-site peeling and shearing tests using a tensile machine. - Seam Treatment:
Heat welding is used for seam treatment.
The overlap width of seams between membranes is generally not less than 10cm.
Arrange welds parallel to the maximum slope, following the slope direction.
Pay continuous attention to the welding machine’s operation, fine-tuning speed and temperature as needed. - Lengthwise Splicing:
When the HDPE geomembrane liner length is insufficient, lengthwise splicing is necessary.
Weld transverse seams first and then longitudinal seams.
Transverse welds over 50cm apart should form a T-shape and cannot cross.
Stagger and overlap adjacent hdpe liner welds as much as possible.
Minimize cross-shaped nodes; use an extrusion welding machine to strengthen the intersection points of the longitudinal die to the weld seam. - Laying:
Aim to lay from top to bottom, minimizing welds to save raw materials while ensuring quality.
Flatten and tightly attach the space between membranes and between membranes and the base surface.
Ensure the laying is not too tight, avoiding wrinkles. Use sandbags to hold down the HDPE plastic liner after laying a certain thickness to prevent the wind from blowing it up. - Special Locations:
In corners and deformed areas, shorten joint lengths.
Except for special requirements, avoid welds within 1.5 meters of the top slope or stress concentration area on slopes with a slope greater than 1:6.
