Is there a place in Ubon that sells different grades of the smooth brown and white rock and different grades of sand? I drove around some river roads and can only find one kind of sand which is for construction. I'm looking for something finer. I don't need truck loads. I need a few bags.

Pretty vague directions here I'm afraid UT, but if you head into Warin on the Sisaket Road, inside the Ring Road, go past the Dtac building and keep your eyes peeled and there is a shop further on that sells raw building amterials .. including sand.

Also, on the junction of the Ring and Kantharalak Roads, on the north-east quadrant, is a similar yard that sells stone and sand,
