Notes:

1. Betonamit is usually not cost effective in slabs less than 5" thick. A pavement breaker or hydraulic hammer works well, unless noise is a problem.

2. The most cost effective demolition technique for ledge is often a combination of Betonamit (to produce cracks) and a hydraulic hammer. Drill holes can be spaced out further in this case.

3. Using Betonamit Type R ( Liquid) is much easier than Type S (Putty). It is usually better to drill holes downhill and use Type R, than to drill horizontally and use Type S.

4. The best way to demolish underwater rocks or concrete is to build a coffer dam and pump out the area. Betonamit hardens in fifteen to twenty minutes, after that area can be flooded again.

5. Betonamit must be used in holes ; pouring it into existing cracks in rock will not work.

6. Safety goggles must be worn at all times by everyone in the area . Hard hats and steel toed boots are a good idea on any construction or demolition site. As an added benefit, use of safety gear enhances your professional image in the eyes of the public, and avoids OSHA fines.

7. When using the temperature chart, bear in mind that the actual drill hole temperature may be much higher than the surrounding air temperature if it is in the sun or affected by nearby heat from machinery or from drilling the holes.

8. Cold temperature, hard rock, or holes spaced too far apart can lengthen breaking times. If it did not break overnight - wait a while before assuming failure. Betonamit continues to increase pressure for 3 days.

9. If Betonamit drops below freezing, the reaction will stop, but it will start up again once it thaws.

10. If mixed Betonamit begins to steam in the bucket, add 1/2 gallon or more of water, stir, and throw it away. You've allowed too much time to pass from beginning to mix.

11. If filled holes start to smoke or steam, that is a sign they may be about to blow out. Immediately clear the area of people. The vapors are only steam, and are not hazardous or toxic in any way.

12. Make sure that everyone working with Betonamit understands the possibility of blowouts and has read this technical manual thoroughly.
