It seems that most of soil report classified class H and builders charge extra. Hey there, I was quoted for a H class slab because it has a better strength for soil that might move.. I would rather get extra support in the long run Hi Its nothing wrong with strength of slab either H or M. both depends on content of clay. Class M is moderately reactive and H is highly reactive to clay. All depends on the Engineer who test the soil. I have two reports by two tester and confirm M on one H on the other. i can not understand this....... Three options 1 Ask the liquidator 2 Find another PD customer and ask the source of their report 3 Pay for new report 3 12320 Thanks for your reply. I will just wait and see I guess. Trying to get some more information from our builder. 9 30235 |
