Hi missm, If you are asking about the white plastic piece in the wall the is a weep hole, presumably this part of your decking is above a window/door. If you are asking about the red thing I haven't the faintest idea. Regards S.
Hi missm. They are there so that water that gets through the wall and is captured on the cavity tray weeps out through these plastic channels. You could always paint the a more discrete colour. Regards S .
