YANBU / KSA
WAREHOUSE
Duration:30 days
When fill material under the floor of two large warehouses belonging to delmon products ltd in Yanbu KSA proved inadequate to support high mobile racking, site operations were seriously affected. URETEK were called in as the fastest and most cost effective solution.
URETEK specializes in geopolymer injection processes which allowed restoration of settled warehouse and factory flooring to level without excavations. The lack of disruption usually means that facilities can continue in commercial use while repairs are carried out. Expanding geopolymer resins are injected through 15- 20 mm diameter holes drilled through the floor slab. The material immediately expands aggressively to fill voids, and further injection can then be carried out to provide upward expansion, to gently lift flooring back to level. The degree of lift is precisely controlled by laser level monitoring.
"Replacing a warehouse floor slab is incredibly expensive anyway, but this would have been double the cost because of having to include a new set of rails for the racking, which was incorporated into the slab."
Eng.Maged Mamdouh (Projects Associates Manager at Delmon products Ltd.)
"If we hadn't used geopolymer injection, the warehouse would have had to have all the mobile racking dismantled and taken away. I could imagine there would have been four months or more for each of the warehouses to be without storage facilities in half their areas, which wouldn't have been acceptable."
URETEK teams first tackled 'hot spots' in the flooring, to enable the racking system to work on a temporary basis.
This provided enough time to plan for a wholesale lifting of two sections of the warehouse floors to achieve a very tight tolerance across any diagonal in any particular bank of racks.
The URETEK team took about 30 days in total for the complete work, but were able to move from section to section leaving the rest of the warehouse operating normally. Dealing with each particular bank of racking only took about 6 days.
URETEK were able to hit the target figures within a millimetre, which put the warehouse back within the required tolerance for the racking.
