Rebar Scanning & Cover Meter Testing in Chennai
Frequently Asked Questions
Why is concrete cover depth so important in Chennai?+
Chennai's coastal air contains high levels of chlorides (salt). If the concrete cover over the steel is less than the IS Code requirement (e.g., 40mm for columns), the salt reaches the steel quickly, causing aggressive rusting and concrete spalling.
Can you tell me if the builder used the correct amount of steel?+
Yes. If your structural drawing specifies 16mm rods at 150mm spacing, our scanner can verify if the contractor actually placed them at 150mm spacing or stretched them to 200mm to save money.
Is Rebar Scanning required before Core Testing?+
Absolutely. A core cutting machine uses a diamond drill bit. If you drill blindly and cut through a main load-bearing rebar, you permanently weaken the building. Scanning finds the gaps between the rebars so we can safely extract a concrete core.
How deep can the scanner see?+
A standard electromagnetic Cover Meter is highly accurate up to 100mm-120mm deep. For deeper elements like massive pile caps, we use Ground Penetrating Radar (GPR) which can scan several feet deep.
