These products are designed to lay underground aquifers at a distance of more than a meter from any structure or directly below it. Pragma polypropylene pipes have a very useful structural indicator — ring flexibility. Engineers call such a quality elasticity, because, being under the influence of vertical loads, products can be deformed very elastic. Moreover, their structure does not change at all, but simply takes the form of an ellipse. Such deforming pipes act on the soil according to the principle of the reverse reaction, which significantly decreases the tension of bending. This unique ability of the product to return to the initial position means that when a load caused by the transmission of the soil occurs, the pipe of pragma retains its original shape, and all the acting voltage is redirected to the ground. Hard pipes do not have the ability to adapt, so they accept all the arising loads on their structure. This leads to the formation of cracks on the case of the product, which, subsequently, leads to its failure.
