Boring Monitoring Wells Under Concrete Surfaces

Installing monitoring wells is an integral part of environmental construction. Its environmental implications include study of ground water, soil sampling, measuring pollutants, site testing, identifying source of contamination, remediation of pollutants and performing analytical studies. Accuracy of these studies depends heavily on collecting samples free of contamination which may seep in from the drilling equipment.

Monitoring well box placement often requires boring under concrete and asphalt surfaces. Traditional well boring methods such as augering and direct push are difficult to execute on such hard planes. Sections of concrete/asphalt surface first need to be removed so underlying softer layers can be accessed for the conventional monitoring well boring procedures to be carried out.

Concrete Cutting Methods

Contemporary ways of cutting through hard surfaces are concrete coring and flat sawing, controlled procedures that use state-of-the-art diamond cutting tools to achieve preciseness and smooth finish. What's more, the use of water in these procedures leaves the site practically dust and mess free.

Concrete coring also called core drilling removes cylindrical cores from concrete/asphalt surfaces. The procedure is used to drill perfect holes ranging in diameter from half-an-inch to over 60 inches. Smaller holes are ideal for boring monitoring wells, extract concrete samples for analytical purposes, installing dowel bars and accommodating utility items such as electrical wires, cables and pipes.

Flat sawing or slab sawing is the process of removing square or rectangular blocks of hard surfaces as those of pavements, decks and floors. The procedure is best used for accessing broken pipes, damaged sewage lines, repairing runways, patching up highways and digging trenches.

Safety First

The sophisticated tools used for concrete coring and flat sawing do not in any way undermine the importance of safety. On the contrary, they call for a more diligent approach towards practicing safety measures.

• Drilling through concrete requires people who have been specially trained as per the procedural requirements.
• Pay attention to the principles of Loss Prevention System (LPS), a behavior based set of tools focusing on non-occurrence of accidents.
• Use the recommended personal protective equipment (PPE) including safety glasses, protective clothing, shoes, helmets and other relevant gear which saves workers from injury at construction sites.
• Cordon off the area temporarily and display appropriate warning signs.
• Though concrete drilling equipment is available on rent, untrained people should avoid doing these activities. Invest in professional help which turns out to be more economical in the long run.

Experts agree about concrete coring and flat sawing being literally the cutting edge steps in the bigger picture of environmental construction. Seeking specialists' expertise ensures loss prevention, saves precious time and gets the work done without any trouble.

I see my Spark Plug hole Bubbling with Spark Plug in it, how big do Heli-cores go?

Ok. Seems ALL my Sealers may be to no avail.. I see them coming through the Spark Plug hole. SO, even though my Gasket s fine.. it may be losing the Compresison there, at Spark Plug hole (I see Bublbing at the base of it..) ... so it MAY hesitate. At least now i know what it is.

.. How big do Heli-Cores go? i am going to get some ChopSticks and J-B Weld, to seal it off more.. but i DO wonder how big a Heli-Core can go, as i am sure that a large enouh one will solve the problem. )Spark Plugs CAN be changed on a Heli-cored Cylinder,right?)

Thanks. i will hope for the best, i hope the K&W and Oil Sealers stopped up that Bubbling somehow, its in a tough spot, Gaskets are sealed the car WILL run perfect, im soo anxious to see its behavior tomorrow, its sealing now, and J-B Weld here i come.. (Explains the Seepage i saw.. but i used the Sealers today, so thats why Hesitation that was happening. I want to see if it wil Continue to happen)...

you cant have a heli-coil on a spark plug hole, the gap between the coils will make your leak worse. there are inserts for spark plug holes but they need the special tap and installer to expand them and lock them in place, not a napa item. are you sure the threads are bad, there are tapered seat, as well as gasketed spark plugs. if at some time the wrong ones were installed they would not seal well.
