Technical information on the use of betonamit

Cracking always occurs in the direction of least resistance. A larger drill hole diameter means more force, shorter reaction time and wider crack formation. Smaller distances between the drill holes mean smaller fragments and a shorter reaction time.

Material consumption

The material consumption is calculated from the sum of the depths of all boreholes multiplied by the corresponding factor (table) of the borehole diameter used. In the table you will find the factors in the most common weight and length units of the construction industry as well as in combination.

Examples

They have 15 drill holes (ø 35mm) with a depth of 0.6 meters
Factor for ø 35 mm: 1.6 (table)
15 holes x 0.6 m x 1.6 kg = 14.4 kg BETONAMIT®

They have 15 drill holes (ø 1 ½”) with a depth of 5 feet
Factor for ø 1 ½”: 1.4 (table)
15 holes x 5 feet x 1.4 lbs = 105 lbs BETONAMIT®

Technical data

The following table shows the expected reaction time as a function of temperature. You will also find further helpful information on the application here. As the drill hole diameter has an enormous effect on the expansion force and reaction time, we recommend selecting the largest possible drill bit wherever possible. (40 mm, 1 ½”)
