Masonry jointing




Masonry jointing

Masonry jointing

Masonry constructions, especially historic masonry constructions, are particularly vulnerable to weather conditions. Unrendered areas, which are even more adversely affected by environmental and weather-related effects, make it particularly easy for water to wash out, deepen and erode masonry joints and hollow spaces. Sound rejointing is therefore indispensable.

Besides manual jointing with formulation or factory-mixed mortar, shotcreting now provides jointing, which is of entirely equivalent quality. Historic masonry constructions in particular exhibit uneven joint widths and depths in irregular natural stone masonry and shotcreting now gives the opportunity to remedy these gaps significantly more cost-effective and much more flexible in terms of time. The work can be carried out in the approved manner and in a way that meets the aesthetic requirements that apply in connection with historic buildings.

Deep wall joints and hard-to-access hollow spaces can now be sensitively filled without undesirable side effects such as load redistributions.
The pulsation-free delivery of the shotcrete also makes it possible to prevent entire walls being plastered in an unsightly way, as the shotcrete is applied to the surface evenly and homogeneously and seals perfectly. Another factor in favor of our machine technology is the significantly-reduced material rebound.
Together with institutes for material testing, universities and various research facilities, we always expose our machine technology to new challenges.

Thanks to the modification to the structure of the base frame, the mobility of the machine has become significantly easier.

The adjustment of the machine has been optimized. The operating elements for adjustment have now been arranged in the center of the construction. In doing so, the limit switch for the funnel sieve was redesigned.

In all other aspects, it corresponds to the performance and equipment of the 'old' generation.
