Concrete Slabs: Seeing is Deceiving

conduit-concrete wallConcrete slabs can be very deceiving.

“It’s just a wall” or “It’s just a floor” or “What can possibly be in there?” These are statements we hear on our client job-sites practically every day.

At a first glance those concrete slabs and walls don’t appear to pose any hazard. They’re just benign structures after all; or are they?

The answer to that question can potentially be lethal if you have to find out the hard way.

lectrical conduits and other utilities buried inside of concrete structures are a complete mystery to most people. There’s no real reason to think they even exist as we seldom see any evidence to suggest it.


Many of you reading this will be familiar with utilities buried in the ground outside. While you may not know their exact whereabouts you will likely have some indication they’re there when you need to know. They kind of announce their own presence by way of visible features such as a fire hydrant on a water line, a valve cover for a gas line, or transformers and utility poles for electric and communications etc.

There are often no such indications or warnings of utilities hidden away inside a concrete slab.

But, you need to cut that slab open or drill or core through it now?

How will you miss hitting any live electric, you may want to know? Let that sink in for a minute.  

Okay, time’s up.

Since the advent about 15 years ago of very high-resolution, portable, concrete-scanning, Ground Penetrating Radar systems (GPR), we at Utility Survey Corp. have been helping clients solve this dilemma and making their job-sites safe-sites.

concrete-investigation.jpgYou can’t just do nothing and hope for the best as you cut or drill into a concrete structure. This is not a viable option. You need to know what’s inside that floor or wall or ceiling before something bad happens. It’s imperative that you have the slab scanned before attempting any cutting, drilling or coring. The risks are too many for you to think of doing otherwise.

It’s never a good idea to take chances when it comes safety.

Following our "10-Step Concrete Structure Scanning Protocol™",  Utility Survey Corp. technicians will unravel the mysteries that lie inside those concrete structures.

This will provide you with a non-invasive, cost-effective, and safe working environment and allow you to proceed with confidence in your cutting and drilling endeavors.

Our advanced hi-resolutionGPR systems can “see” those conduits, post-tension cables, rebar and mesh.  We can even find voids and delamination and tell you slab-thickness.

We can help save you from a whole lot of trouble!

So call us now if you’re ready to start work - or even if you’re still at the design and planning stage.

Safety is our priority and it should be yours too.
