Ten Years or more ago, someone got a hot idea to build a marina in a man made inlet off the St John River near Fredericton NB..a big dig ensued..and then the excavation was lined with tires fiiled with crushed stone. Two probems ensued..the tire walls were not set back far enough and the good old frost shoved them in. Then the gummint decided the whole dig violated the watershed protection act and screwed up the fish. The gummint ordered the marina owner to remove the whole shebang and fill in the dig. The yuppies had no place to park their yachts over the summer..so they all went to a floating dock marina about 50 miles downstream..owned by a former federal government member of parliament, who had the influence to get a lease on the "waterlot" in the river where the floating marina is located. There is over 600 feet of floating wharfage there which must be pulled every winter. Yachties pay about 12 bucks a linear foot for wharfage space...per day.
Dear dee dear..I wonder how the ex-politico is getting by on the $72,000 per day he gets for rent? And I wonder if it made a darn bit of difference to the fish ecology in the heavily polluted St John River?
Burying rubber tires for a roadbed is really not effective because of frost heave of the water in the voids.
Crushed stone over permeable filter fabric geotextile does work, even for heavy vehicles on swampy ground.
I built one in 1990 that supports 25 heavy trucks driving in and out over it every day..winter or summer.
It is a quick and cost effective alternative to bedrock foundation roadbeds..but it requires a minimum of 12 " of crush over top to prevent destruction of the membrane. mixing in some sand with the crush gives a reasonable surface that will drain well, too. It is not, by comparision, a costly solution. My project covered half an acre, and cost 12,000 dollars in 1990, all costs in...That's about fifty cents a square foot ready to go.
And it was built over two foot thick black swamp ooze, that had been drained, but not excavated.
Still going strong after twenty four years...and it does not break axles on loaded garbage trucks, buses or heavy equipment, best of all, it does not trap surface water.
