Equipment needed

The equipment necessary to do the grouting work on any of the above cases should be a pressure pump suitable to handle cement grout with a mixture of five and one-half to six gallons of water per 94-lb. bag of cement.

The best pump for cementing jobs up to 50 to 75 sacks is a small power-driven reciprocating pump powered to deliver 100 pounds pressure.

For very small amounts of cement there is nothing wrong with using a hand force pump, commonly known as tank pumps.

The next essential piece of equipment necessary is a receiving tank or tub for cement.

A common stock tank with a good heavy screen, with a one-quarter inch opening installed about one-third from one end, makes a satisfactory receptacle.

It is necessary to keep lumps and any stringy material out of the pump.

A short suction hose with quick-mate coupling should be used on the pump end.

The mixing of cement can be accomplished by any method: cement mixer, mortar mixer, by hand, or you can have a company deliver cement already mixed.

It is well to remember that mix must be as free of lumps or any aggregate material as possible.

The screen on the receiving tank will take care of just so much of the lumps and foreign material.

It is discouraging to have valve and pump trouble while cementing.

The cleaner the cement, the smoother the job.

It is essential to have an ample supply of good clean water available; above that required for mixing cement.

Water under pressure is the only way you can remove cement if something goes wrong.

A defective cement shoe or split casing, or bridged annular space, often develops after cementing has started and with ample water, the cement can be circulated to the surface or the cement can be diluted so that it will not harden.

You then can remove the casing and correct the situation.
