--=_f7727f93af3bdada8843f407bc999a8c MIME-Version: 1.0 Content-Type: text/plain Hello Cobbers! I build small cob-strawbale cottage about 12x12 foot. The ground beneath cottage is very sandy - 10 inch soil and then only fine sand. The winter is very cold in our climate (0 until -25 by celsius, like middle Canada or so). I built roof structure and digged trench. Next I will fill trench with 1-5 inch diameter small stones (like "big" rubble). The cottage floor will be made from sand-clay. Foundation will be stones with lime-cement mortar. 1. My question is about trench filling. Do I have to fill gaps between trench stones (between rubble rocks) with sand/gravel? When I do not fill gaps, then the sand/gravel from floor base might flow into the gaps beneath foundation. As a result the floor will be damaged. The second option is to cover the rubble trench (stones) vertically with some kind of landscape plastic and protect that way the gaps between stones. 2. I have heard that some builders fill the trench with big stones (5-12 inch stone) and then fill the gaps with sand or gravel. Does anybody has experience with such kind of sand and stone filled trench? What are probable dangers with or without sand filling (water stands and frost etc)?
