Min height under beam and block.

[Russell griffiths]

So after talking to 3 piling company’s and 2 structural engineers it looks like we’re having beam and block floors

against my better judgment I may add. 

 

So the question is what is the minimum void height under the beams. Got to have a re design. 

Thanks russ.

150mm

i did hear recently something about a max of 225 in case someone falls through but that could just be heresay. 

 

Edit: actually reading the link says you might get away with 75mm depending on soil type and location but I was always told 150
