Where can I send building insulation materials for inspection in Chengdu?

Hello, the external wall insulation materials should be sent to a qualified testing center. You can send insulation materials to any test center, and other materials of your project will also be sent to the test center. You can ask the person who subcontracts the external wall insulation to deliver it yourself. Just fill in the names of Party A, Party B, contractor and project. The list shall be signed and sealed by the supervisor. Generally, 4 pieces of extruded board, bonding mortar, anti-crack mortar and alkali-resistant grid cloth are sent, and no anchorage is sent. The unqualified materials for inspection have nothing to do with you, so there is no need to do it. It was also made by subcontractors. When the engineering plate and anchor are on the wall, the pull-out test will be carried out. You can't hand it in without making insulation breakdown data. This has something to do with you. Remember to ask the subcontractor to contact the site for inspection.
