Panel Layout:
Prior to commencement of liner deployment, layout drawings shall be produced to indicate the panel configuration and general location of field seams for the project. The panel layout may be changed depending upon field conditions. Cross seams may be added at any location.
Identification:
Each panel used for the installation shall be given a numeric or alpha-numeric identifier. This panel identification number shall be related on the Krizs Panel Placement Form .
Weather Conditions:
Geomembrane deployment will generally not be done during any precipitation, in the presence of excessive moisture (i.e. fog, dew), in an area of standing water, of during high winds.
Method of Deployment:
The method and equipment used to deploy the panels must not damage the Geomembrane or the supporting subgrade surface.
No personnel working on the Geomembrane will wear shoes that can damage the Geomembrane or engage in actions which could result in damage to the Geomembrane.
Adequate temporary loading and/or anchoring, (i.e. sandbags, tires), which will not damage the Geomembrane, will be placed to prevent uplift of the Geomembrane by wind.
The Geomembrane will be deployed in a manner to minimize wrinkles.
Any are of a panel seriously damaged (torn, twisted, or crimped) will be marked and repaired.
General Requirements:
Layout:
In general, seams shall be oriented parallel to the slope, i.e., oriented along, not across the slope. Whenever possible, horizontal seams should be located on the base of the cell, not less than 0.2 m from the toe of the slope. Each seam made in the field shall be numbered and indicated on the record drawings. Seaming information to include seam number, welder ID, temperature setting, and weather conditions mentioned on Krizs Geosynthetics Form. |
