Problem
A commercial property in Holbrook, NY required the installation of a high-performance concrete slab as part of a facility upgrade. The client needed a durable slab capable of supporting industrial loads with proper moisture protection, structural reinforcement, and long-term stability. In addition to the new slab, the existing deteriorated surface had to be removed with precision to avoid damaging surrounding structures.
Solution
Our experienced team at Zavza Seal approached the project with a comprehensive plan, ensuring compliance with commercial-grade construction standards and structural engineering specifications.
Concrete Slab Demolition and Preparation
We began by performing slab saw cutting to isolate the areas to be demolished. This method allowed us to minimize disruption and avoid structural impact to the surrounding floor. Using high-precision tools, we carried out concrete demolition to remove the existing slab, making way for the new installation.
Backfilling, Compression, and Site Preparation
Once demolition was complete, the area was backfilled with compacted gravel to establish a stable and level subbase. We employed heavy-duty machinery to ensure full compression of the subgrade, preventing future slab settlement or uneven load distribution. Proper dowel drilling was conducted to prepare for rebar insertion, enhancing the connection between the new slab and adjacent sections.
Reinforced Slab Installation with Vapor Barrier Protection
To address moisture protection, a 10 ML vapor barrier was installed across the gravel fill. This crucial layer prevents moisture migration from the ground into the slab, protecting both the structure and future interior finishes.
We then placed a 5-inch thick 4500 PSI concrete slab, reinforced with #5 smooth bar dowels extending 20 feet to provide structural integrity. These dowels were placed on grade in alignment with the drilled holes to ensure a seamless connection and reinforcement across slab joints.
Our team ensured that all work, from vapor barrier installation to slab pouring, was performed according to engineering requirements and local code regulations.
Results
The new commercial-grade concrete slab in Holbrook, NY was successfully completed and delivered superior strength, moisture protection, and long-term performance. The use of 4500 PSI concrete, combined with #5 smooth bar dowels, gravel fill, and a vapor barrier, ensures that the slab will perform under high load conditions and varying environmental factors.
This project not only improved the structural reliability of the commercial property but also showcased Zavza Seal’s ability to handle precision-based concrete slab installation for demanding environments.
