The Problem:
The owner of two retail spaces in Farmingdale, NY contacted Zavza Seal after noticing uneven concrete floors and visible cracking inside the building. These issues raised concerns about safety, long term damage, and possible business disruption.
Our senior estimator inspected the property. During the inspection, we found clear signs of voids beneath the concrete slabs. These empty spaces had formed under the slabs, reducing support and causing the concrete to settle and crack.
At this stage, the biggest challenge was uncertainty. While it was clear that mudjacking was the correct repair method, the exact size, depth, and location of the voids could not be confirmed through visual inspection alone.
Quoting a full repair without proper investigation would require adding extra costs to cover unknown conditions. This practice is often called cushioning the numbers and can unfairly raise the price for the customer. Zavza Seal does not believe in this approach.
The Solution:
To provide a fair and accurate repair plan, our team recommended exploratory work before performing mudjacking. This step allowed us to fully understand what was happening beneath the concrete slabs and design the most efficient solution.
The exploratory work included:
- Using measuring equipment to locate the voids and determine their depth
- Identifying the exact drilling points needed for mudjacking
- Analyzing how much material would be required to properly fill the voids and stabilize the slabs
Once the exploratory work is completed, our project manager will review all findings with the customer. Our office estimator will then prepare a detailed and transparent mudjacking estimate that includes:
- The exact areas that need to be drilled
- A clear scope of work to fix the voids
- The total cost to complete the repairs
If the customer chooses Zavza Seal to perform the mudjacking work, the cost of the exploratory investigation will be deducted from the final project price.
The Result:
By starting with proper investigation, Zavza Seal ensures the repair is accurate, cost effective, and built to last. This approach protects the customer from overpaying and ensures the concrete slabs are stabilized correctly the first time.
All of our mudjacking solutions come with a 40 year warranty, giving property owners long term peace of mind.
