hiya Linda Taylor2, I'm a builder and bricklaying has been my trade for the last 26yrs.
A brick built base is a good idea and better than the alloy ones you can buy, but BEWARE!
Common bricks or any general facing brick is porous and will absorb water, during the winter months these bricks will remain wet/damp. then when it freezes the water will expand and cause the face of the brick to be blow off, once the face has blow off the brick will continue to erode.
I won't recommend using common or general facing bricks, nor would i use this type of brick to build such a base for a customer as I would not guarantee it and I think in 5 years time you'll wish you hadn't.
The only brick I would use is a none porous brick, A class 2 ENGINEERING BRICK red or blue.
assuming your husband is laying 2 courses, which would make the height of the base 150mm or 6 inches the top course would need to be a solid engineering brick. And these are not so easy to lay as general bricks, but are the only bricks I would be happy to use for a customers job.
also Berghill and Mark Talbot comments above are spot on by saying the brick base needs to be squared and double check the dimensions because 8x6 is really 8'3x6'4.
