99 Ocean Protection Slab
The project site has limited access and doesn’t leave a lot of room for contractors to work. With stockpiling material, staging utilities, and attempting to grade the area, the contractor is faced with a challenge in leveling the site and beginning vertical work.
The contractor would typically install a mat slab or a working pad on top of the site so the activities on top no longer compromise the grading while allowing for staging of materials more effectively. These working slabs can be made of concrete; however, that prevents being able to dig through it in the future and has a much higher cost per unit material.
The Solution
Lightweight Cellular Concrete (LCC) is easily installed on site. Because LCC is batched locally, we don’t need to coordinate multiple trucks like we would with traditional concrete. This coupled with the lower unit price makes LCC the best option for working slabs such as this one.
