Sharjah Airport MTB – Sharjah
Project Overview
CDE Engineering Services was appointed by Sharjah Airport Authority to carry out a detailed structural assessment of the waffle slab system at the Maintenance Terminal Building (MTB) located at Sharjah International Airport.
The objective of the study was to evaluate the structural integrity of the slab system, investigate observed defects, and assess its ability to safely support operational loads.
Client
Sharjah Airport Authority
Location
Sharjah, UAE
Client Challenge
The client observed signs of distress in the waffle slab system, including cracking and potential deterioration in soffit regions.
Given the operational importance of the facility, there were concerns regarding structural performance, durability, and long-term serviceability. A detailed investigation was required to determine the root causes and assess whether the slab could continue to function safely.
Scope of Work
Our Approach
CDE carried out a systematic investigation combining field inspection, testing, and structural evaluation.
Visual inspection and hammer sounding were used to identify areas of delamination and cracking. Testing methods were employed to assess concrete quality, reinforcement condition, and extent of deterioration.
The structural behaviour of the waffle slab system was evaluated to determine whether the observed defects had any impact on load-carrying capacity and serviceability.
Key Findings
Cracks were observed in the waffle slab system, particularly in soffit regions. These were primarily associated with shrinkage, temperature effects, and long-term service conditions rather than immediate structural failure.
Concrete quality was found to be generally adequate, and no significant structural deficiencies affecting overall stability were identified.
However, localized deterioration and minor defects were present, which could lead to durability concerns if not addressed in a timely manner.
Solutions & Recommendations
CDE recommended targeted repair measures to address localized defects and improve durability.
Cracks were to be sealed using appropriate injection techniques to prevent moisture ingress. Delaminated areas were to be repaired, and protective measures were recommended to enhance durability and prevent future deterioration.
Regular inspection and maintenance were also advised to monitor the condition of the slab system over time.
Outcome
The assessment confirmed that the waffle slab system was structurally adequate for continued use.
Through timely identification of defects and implementation of targeted repair measures, the client was able to ensure continued safe operation while mitigating long-term durability risks.
