Refering to earlier post on kg/m3, I think concrete also exceeded that guideline that's why my ID also say concrete cannot be used and that is also why EPF is the common material used for leveling balcony area. Today only, I received call from my ID saying that HDB disapproved on leveling of my balcony.... I am now waiting for the HDB maintenance officer to call me and trying out to see if anything can be done or not. But base on other ppl experience in this forum, it seems that if I gonna wait for HDB reply, I will have to wait long long.... Such situation suckz, especially when HDB cannot do anything to compromise... Any one have any progress on their balcony floor leveling, please share!
