Construction steps

Full adhesion method: base layer cleaning → pre-laid coil → large surface gluing → laying coil → lap treatment → node strengthening → closing treatment → self-inspection and receipt

Empty paving method: base layer cleaning → pre-laid coil → lap treatment → node reinforcement → self-inspection and acceptance
