'SSRS fixed position of tablix in body of the document. Visual Studio

I have a set of two tablixes which I would like to have fixed in the position marked in red (Bottom of the body). I've tried to put them both in a rectangle but this doesn't work for me.

I am using Visual Studio 2013.

When I print this report as a PDF the tablixes aren't fixed at the preferred position.

Any suggestions on how to fix this?
