Re: Ground anchor installation
IF you don't want to lift a lot of paving consider driving 2' lengths of rebar at 45 degrees through each side of the hole into the subsoil before you pour your concrete. There's hardly any oxygen 2' down so they'll last for decades and make it almost impossible to lift your block.
The only downside is that driving them with a club hammer is a pretty noisy process, so you won't make too many friends in the neighbourhood.
