This has been offered before --now, there is a specific locale that may bring in a new reader:
PROBLEM:
How to hold track absolutely in place and permit it to be walked on for gardening. At the same time allow for track movement for 'expansion?"
MY SUGGESTION:
Take advantage of the track having 'hollow" ties. By placing concrete block wall topper blocks or bricks under the track layout, making sure there is about 5" in between each to save costs, a concrete mortor mix is then applied over and in between the bricks or blocks. The idea is to level the cement with a thickness of about one inch for strength and then drop in place sections of the track – which the ties at the joints have been rubber-banded together to ensure accurate fit. The track is now on TOP of the fresh concrete mix. W-A-I-T a few minutes and then presss the track into the fresh concrete mix. This pressing will fill the opening on the backside of the ties. Now, wiggle the track sideways and back-and-forth slightly to accomodate and track/rail expansion.
RESULT:
The track can be walked on and survive movement. It will NOT need any attachment devices (screws, etc.) as the hollow ties will hold it. I have 400 feet of track held this way – now, approaching 12 years.
it can be walked on. It can be hosed off without blowing out the roadbed – leaves and dirt don’t bother as muc because it is now above the ground level as if on a roadbed prototypically. Enterprizing folk can apply the gravel to the cement with glue in those areas visible for a more "roadbed look.’ Or, simply spray with the rusty brown spray paint available from Home Depot or??
That’s it. The best thing I ever did to ensure minimal maintenance screw-ups.
If you try it, plase report your experience.
