Building Settlement

Point:The building settlement point is to be embedded/ fixed to a vertical member to monitor the vertical settlement/ movement of any structure. It consists of a male anchor fitted into thea nchor socket which in place is usually embedded / fixed in a column / wall of thickness greater than 80mm. These points are best monitored using digital level equipment for the most precise readings.

Bi-reflex Target:

The crack meter is suitable for measuring the width of crack in two directions i.e. in sides and in Up & Down. This is very simple and accurate instrument to monitor the hair crack. The mechanical crack meter is made of polycarbonate transparent sheet with graduated marks. The both sheets will be assembled on crack with the help of fasteners.
