Colossus® Injection Tube is a Single – Walled tube based on PVC provided with opening or slot which become slightly conical from the inside to outside. The opening close due to their geometry and efficiently prevent cement paste from penetrating the transport canal. Colossus® Injection Tube are cut to the length required for their installation . Colossus® Injection Tube are very flexible and adapt perfect to any joint course.
The Individual tube is fitted in such a way that it lies in the construction joint formed during the concreting work. As soon as the concrete start to set it shrinks to form a joints around the injection tube which enables the resin to spread lengthwise. During the injection procedure the resin which is injected via the tube under pressure causes the opening of the slot and fill all existing cavities , gravels , nests and cracks in the joint area durably .
