While performing land surveying services during replacement of the Maerz kiln lining, we had numerous opportunities to verify in practice our methods of determination and marking of relevant axis and levels.

Our measurement techniques exclude the errors which are most frequently made as a result of armour deformation or inclination of the geometrical axis of the shafts.
The pillar axis that we determine is always in plane with the shaft axis and is always vertical. Also, control markers of the given lining layer height are always in plane and are always horizontal, irrespectively of the shell geometry.

This prevents an uneven distribution of chords which define the internal limits of the lining, and your "web" will always be accepted by the construction supervising authority.


We also perform geometry checks of kiln armour and support structures.
Thanks to us you may know

• what the deformation map for each shelf looks like,
• what are the out-of-roundness deviations of successive shaft cross sections,
• what is the 3D image of the curve connecting the geometrical centres of successive circular cross sections at various levels and the deviation values for this curve from the shaft vertical axis,
• what is the shell deformation map at its entire height,
• whether the kiln structure is inclined or settles with time, and if yes, at what rate.
