GPR assists at Archaeological Sites

How Ground Penetrating Radar (GPR) assists at Archaeological Sites.

Ground Penetrating Radar (GPR) has been used for Concrete inspection on building sites for many years now. This same technology is finding many uses in the world of archaeology. In fact a recent discovery made in Egypt was through the use of GPR.

Buried Architecture Discovery

In Egypt an archaeological site located near the Great Temple decided to use GPR to assist in finding further evidence of hidden ruins. The area consists of many sites including what is known as the Lower Market. This was the area chosen for the scans in the hopes of finding buried architecture to identify the next area for excavation.

Concrete scanning

Concrete scanning and its equipment

GPR VS. Electromagnetic

Since safety is our number one priority, we make sure to use the best and most widely used tools in our industry, GPR (Ground Penetrating Radar) and EM (Electromagnetic) equipment.

When scanning a site for utilities, utilizing GPR for the entire site would be beneficial to any project & profit any customer by providing a significant amount of data, due to the radar’s capability to discover non-metallic utilities without any plans or previous information that were any existing in the area.

Assessing GPR

Assessing ground penetrating radar

We have posted different blogs on the different ways and uses of GPR, accordingly we would like to explain how it actually works. In this Blog we give you a description or an assessment of GPR.

GPR mapping can find all utilities, metallic and non-metallic. With Ground Penetrating Radar profiles, you can evaluate the location and depth of buried objects and investigate the presence and continuity of natural subsurface conditions and features.

Locate underground utilities

Why locate underground utilities before drilling in concrete?

In recent years, a number of companies and construction contractors contact us to locate underground utilities in a concrete slab prior to sawing, drilling, etc.

Why?

Often it is clearly stated in the specifications it is absolutely necessary to know what is happening within the concrete slab rebar to prevent material damage (cuts to rebars, electrical conduits, telecom, etc.) but also injuries to the body of the workers on site.

Scan concrete slabs for rebar

How to scan concrete slabs for rebar?

First of, what is rebar? Rebar is a steel bar or mesh of steel wires used as a tension device in reinforced concrete to strengthen and hold the concrete tension. Since concrete isn’t good with tension it needs rebar. Concrete without rebar is a short-term fix, not a good long-term structural choice.

Before you decide to tear up a concrete slab, it is a good idea to know where the rebar is. It is one thing to use equipment to break through a concrete structure, and another to come into contact with metal. The problem with finding rebar is that you cannot see it, and therefore you must use certain types of equipment to discern where it is so that you can break the concrete slab quickly and efficiently.

10 Reasons to consider Underground Utility Locating

    1. Protecting employees: The # 1 concern in construction projects  is security. Safety & security for workers builds loyalty and quality of work from employees.
    2. Your Client’s Trust: When your client can see that you take safety and the protection of THEIR infrastructure seriously, a long-term relationship may be the fruit of their well-placed trust.

Conduit detection at the construction stage?

Why drilling conduits before detection is it too often at the construction stage?

When we are contacted by generals and/or specialized contractors, they often arrive only when we scan the prescribed places, we then have to move the drill because of ducts, reinforcement bars or obstacles. This causes a lot of costs for all project stakeholders, all sorts of extras, loss of time & money, etc.

Why not scan in the planning stage as this would reduce all problematic issues considerably? Are contractors and consulting engineering firms ready for this change?
