Do you want it all one solid texture pattern or the ground to look seperate from the background?

For solid "procedural" texture, you can select "Background" in the Material Room and apply the Brick or whatever texture to the "BGColor" - it doesn't show up in the preview window but it will in the render. May take some work with scaling and such to get it like you want it.
