Arase strip : what interest for your cinder block wall ?

The term ‘araser’ is commonly used in masonry and it means flush, smooth, smooth. For good construction, it is used before, but also after work. However, the arase strip is a soft sheet about 2 mm thick made on the basis of bitumen and composites. The arase strip serves as a basis for avoiding problems with capillary uplifts of moisture that comes from the floor in the walls of houses. Generally speaking, it is installed at the foot of a wall.

Role of arase strip under construction

The arase strip is not only used to combat moisture. It is also used as a waterproofing barrier under bay and window sills. By the way, the arase strip is laid dry on a previously taloated cement mortar layer with a thickness approx. 2 cm. It should be noted that the cement must first be dry, and then add a second layer of cement mortar, which serves as a protection during construction. Also, note that it is not necessary to weld or glue the arase strips since simply adhering to one overlap that involves one strip on the other is sufficient. Nevertheless, a distance of about 25 cm should be observed. In clear, the arase strip is important to prevent long-term wall erosion.
