building a concrete ramp

[bhads]

Hi

I've built an 8m double thickness wall which is about a 1m high in my back garden and runs parrallel to the back wall of my house. This acts as a retaining wall for about 600mm of soil and hardcore topped with slabs. At the side of this wall, I've turned a corner and built two more walls perpindicular to the 8m wall. These are 1m apart and are a length of 2.5m. I wish to build a concrete ramp between these, but can't find much info on the method of construction.

Thanks for any advice.

Pour in loads of rubble and shape it to suit. Ask for rubble and hardcore from building sites around you, all their old unused stuff. Try to bump it down as much as you can with a small board and jumping on it, just to pack it down as tightly as you can. Or you could hire a proper roller for this job. Once it's to the shape and length you want it to be, then pour a few inches of concrete on top and allow it to cure.

I made a small ramp with a 1:5 mix of cement and 3/4"-to-dust ballast. It was quite possible to shape it without using a mould or shuttering of any sort, as the larger components of the ballast lock together to prevent it fro slumping. Of course, I would not go for a runny mix. The previous posters idea about using rubble may well save you the cost of using too much cement etc.
