Significant heaving from slab to slab.

Approximately 10"-12" Creating hazards for

pedestrian and wheeled traffic.



The hypothesis was that the grates were rusted and creating pressure on the slabs.

Exploratory slab removal to identify any flowing water or unknown variables under the slab.




HSS saw cut to remove the pressure off of the slabs.

Removal of concrete surrounding the drain.

Rebuilt the drains and replaced/reset the grates.

"Your crew was amazing and got the project done on time and re-opened

with a clean garage! ...the project was completed without a hitch!"

Structural cracking in the webs and flange of the

double T panels caused by overloaded weight

distribution on the upper deck of the parking structure. 



A structural engineer was brought in to assist in assessing the damages.

The options were to either repair and add supplemental steel or remove

and replace the 6 deteriorated panels. Ultimately the owner decided to

remove/replace due to the similar cost of repair.



HSS disconnected the panels, demoed the pour strips and broke everything

free. Spancrete set the 6 new panels with a crane and over the next six

weeks HSS installed all connections, expansion joints, pour-strips, sealants

and membrane.


“They are responsive, very competitive with pricing and care as much 

about our projects as we do...I would highly recommend

HSS to anyone looking for quality work at a fair price.”
