The National Electrical Code (NEC) basically allows mechanical
compression joints and exothermic joints.
You are correct that corrosion is more likely with buried rods and
clamps- that's the primary reason for ground system degradation and rising
resistance. Use of good fittings and anti-oxidant paste will give you the best
chance for a reliable system.
Exothermic welding systems like Cadweld and others are the preferred,
albeit more expensive, methods. A web search should turn up some
distributers/dealers.
