Welcome to 2022 and happy new year! At CSI, we’re sharing our recent drossbach investigation and how it helped us […]
Drossbach investigation demonstrated that apartment blocks drossbach’s were filled (the owners were uncertain); thereby putting apartment dwellers minds at rest.
The journey to finding unfilled drossbachs has been a fairly long one. Drossbachs are the glue that stitches the panels together (precast columns and precast walls are often connected using drossbachs). It came to CSI’s attention approximately 6 years ago, when we found that by using ultrasonics we could non-destructively discover whether or not drossbachs had been grout filled.
There was a bit of a groundswell of concern after CSI worked with one engineer in particular, as part of an overall investigation of a large apartment complex. This groundswell resulted in a committee (CSI is currently a member), that started investigating the frequency of substandard work, with the aim to report their findings to SESOC.
The ultrasonic device CSI uses proved to be very effective and cost-effective for this purpose. It was recently that CSI was approached by a Body Corporate who had a series of issues with their building, and their concern was that the drossbachs may have been executed in the same sub-standard manner. This was keeping some of the apartment dwellers awake at night; no doubt the events in Miami wouldn’t have helped.
While it is disappointing to find so many poorly executed drossbach installations; in this case, the drossbachs were filled and the apartment dwellers were able to sleep easier. It was nice to pass on good news!!
