LEADTOOLS has a simple method call that will allow you to combine PDFs into a singular document.
Both of the attached console applications utilize the latest from LEADTOOLS v20.

C#

Code:

using Leadtools;
using Leadtools.Codecs;
using Leadtools.Pdf;

namespace simplePDFMerge_20
{
    class Program
    {
        static void Main(string[] args)
        {
            //set your license file here
            RasterSupport.SetLicense("", "");

            string pdf1 = @"C:\Users\cthompson\Desktop\Leadtools.pdf";
            string pdf2 = @"C:\Users\cthompson\Desktop\Leadtools.pdf";
            string pdf3 = @"C:\Users\cthompson\Desktop\Leadtools.pdf";

            string destinationFilePath = @"C:\Users\cthompson\Desktop\combinedTest.pdf";

            const string pdfEngineLocation = @"D:\LEAD15\Dist\Bin20\Dotnet4\Win32"; //file path of the Leadtools.pdfengine.dll

            RasterCodecs codecs = new RasterCodecs();
            codecs.Options.Pdf.InitialPath = pdfEngineLocation;

            PDFFile pdfFile = new PDFFile(pdf1);
            pdfFile.MergeWith(new string[] { pdf2, pdf3 }, destinationFilePath);
        }
    }
}

Code:

Imports Leadtools
Imports Leadtools.Codecs
Imports Leadtools.Pdf
Module Module1

    Sub Main()
        'Enter you license and ke files here
        RasterSupport.SetLicense("", "")

        Dim pdf1 As String = "C:\Users\cthompson\Desktop\Leadtools.pdf"
        Dim pdf2 As String = "C:\Users\cthompson\Desktop\Leadtools.pdf"
        Dim pdf3 As String = "C:\Users\cthompson\Desktop\Leadtools.pdf"

        Dim destinationFilePath As String = "C:\Users\cthompson\Desktop\merge.pdf"

        Const pdfEngineLocation As String = "D:\LEAD15\Dist\Bin20\Dotnet4\Win32"

        Dim codecs = New RasterCodecs()
        codecs.Options.Pdf.InitialPath = pdfEngineLocation

        Dim pdfFile = New PDFFile(pdf1)
        pdfFile.MergeWith(New String() {pdf2, pdf3}, destinationFilePath)


    End Sub

End Module
