Retaining wall APP membrane work refers to the installation of an APP (Atactic Polypropylene) membrane on a retaining wall. The purpose of this membrane is to provide waterproofing and protect the structure from water infiltration and potential damage.The retaining wall surface needs to be properly cleaned and prepared before membrane installation. This typically involves removing any loose debris, dirt, or existing coatings that may interfere with adhesion. A primer is often applied to the retaining wall surface to improve adhesion between the membrane and the wall. The primer is typically a specialized adhesive that enhances the bonding properties of the membrane. The APP membrane is then applied to the prepared surface of the retaining wall. The membrane is typically supplied in rolls and is rolled out onto the wall, ensuring proper alignment and overlap between adjacent sheets. The membrane is then pressed firmly onto the wall surface to ensure good contact and adhesion. Special attention is given to the treatment of joints, corners, and any penetrations in the retaining wall. These areas are reinforced with additional membrane material or specialized flashing to ensure watertightness and prevent water intrusion at vulnerable points. Once the membrane is installed, it is important to protect it from damage during backfilling or subsequent construction activities. Protective layers, such as geotextile fabric, may be installed over the membrane to provide an additional safeguard against punctures or abrasions.
