DS Slab Evaluation

At Durable Surfaces, we long ago recognized the need for an analytical, reliable and repeatable method for evaluating the condition of slabs in industrial or commercial facilities. This led us to develop the industry’s first slab-evaluation protocol in 2004. This proprietary process allows our experts to perform an extensive multi-point inspection and analysis of your facility. We then can provide budget costs for immediate repairs as well as a five-year budgets for potential future maintenance.

As a well-established industry leader, Durable Surfaces is uniquely qualified to perform this evaluation. We have the capability, knowledge, experience and expertise to identify issues at your facility and provide estimates to repair and remedy your specific challenges. Upon completion, we’ll issue you a detailed and comprehensive proposal that outlines the steps needed and associated costs to restore your slab to industry standards. This proposal also includes the routine preventive maintenance required to preserve your slab’s up-to-industry standards.

Recognized across the nation as a concrete authority, we identify many of the nation’s largest retailers and companies as our customers.

We have identified three phases in the life cycle of a building where we can offer these services.

1. Slab commissioning report – New facilities and turn over lease facilities.
2. Slab warranty – New facilities, maintenance programs and assessment of new facilities prior to the warranty period ending.
3. Slab assessments – Slab assessments will be done for new and old facilities; and can be used as a tool for facility purchases and sales, or for tenants to document the condition of a slab in the beginning and termination of a lease.

Below is an overview of some of the factors we use to perform our DS Slab Evaluations. The Slab Evaluations enables building owners, developers, managers and others to easily understand what the baseline of the facility is, plan for any required corrective action and even gain access to the associated costs.

Photographs, empirical data and field measurements will be taken and included in the DS Slab Evaluation field report. This data can then be used for immediate or future negotiation, including the process by which a benchmark is set for usage difference or in determining normal wear and tear.

Overall quality of floor slab

Our experts visually evaluate the cleanliness and quality of your slab, taking into consideration the following factors:

Slab Movement / Joint Rocking

We’ll conduct an evaluation for movement, rocking and stabilization issues (e.g., voids under slabs and poor or low-quality sub-grade compaction). This movement is caused by loaded forklifts being run over curled joints.

Curled Joints

We’ll evaluate your slab for a Q value, which are measurements that establish floor flatness and levelness over the joints, which both contribute to the overall quality of the floor. The higher your measurement, the better the slab. If there are signs of curling, our experts will conduct further evaluations to determine whether the slab is experiencing any failure.

Joint Fill Quality

We’ll perform a visual and mechanical inspection of your facility’s joint fill by evaluating all joints that may experience failure due to high use and/or lack of maintenance of the joint filler. Failed or neglected joint filler is the leading cause of deteriorating joints which lead to spalls, increased future maintenance costs and higher forklift maintenance costs at the facility.

Crack Evaluation

We’ll evaluate your slab for the presence of cracks that require repair. If neglected, cracks can deteriorate rapidly and create spalled conditions which pose both potential safety issues and increases in future maintenance costs.


Our team evaluates your slab for any spalling conditions which are detrimental to facility logistics and affect your ability to maintain a quality slab. Spalls are not only destructive but they also impact the maintenance cost and integrity of equipment used on the floor.

Damaged / Deteriorating Concrete

We’ll assess your slab’s overall condition, identifying all damaged or deteriorating areas. This assessment includes, but is not limited to, areas that need to be repaired, removed and/or replaced. Collapsed concrete and other damages that affect the usability and integrity of your slab must be properly evaluated, repaired and maintained to protect the value and longevity of your facility.
