Betongfoten gjuts i form innan stolpen sätts på plats i hålet. Med en stor jordborr får man "lagom" mycket hål, så sätter man trästolpar. Stålstolpar grävs ned på klassiskt vis, för hand eller med maskin beroende på var och när.

Numera ja.

Men "förr" var det väl platsgjutna fundament som gällde. För att få ett få ett fyrkantigt fundament fick man bygga en träform i hålet. [link=http://www.jvmv2.se/forum/index.php?mode=thread&id=45356]Den här bildserien[/link] fokuserar mer på hur stolpen restes med handspel, men man kan se lite av gjutformen också.
