With the DDL SANI-Pipe you can securely and permanently seal problematic areas/transitions between the carrier pipe and the underground. Given that the Sani-Pipe elements are not attached mechanically but fixed with a particularly elastic glue, the forces produced by movements of the carrier pipes do not directly affect them. Their form allows for an absorption of the transferred tensions. Even heavy strain will not lead to cracks in the sealing elements or tensions at the glued spots (which could impair the fastening and lead to undermining). At the same time, the excellent adhesive characteristics of the glue provide an effective sealing against water. Only one step is needed to fasten and seal the DDL Sani-Pipe elements. Another advantage of our Sani-Pipe is that it can be attached to spots where water is damming (outside, on the sealing level) and so stop the water from entering the components in the first place. The outside installation of the Sani-Pipe elements (made of rigid plastic) offers additional security to the penetration, especially when ring seals are used.
