SANDO SP is specialised in waterblocking and waterproofing filling compounds for all sorts of cables like communication and power cables, as well as for cable-joints, couplings and similar cable material.

Most of our products have been developed for special purposes and are meant to be used in those cases where the standard cable fillers fail or give insufficient result.

The capability to provide relatively small quantities of special products also offers the possibility to develop and supply custom-made specialities in order to meet our clients problems.

During our more than 20 years’ experience we developed two standard groups of waterblocking compounds which we like to propose as follows:


Natural rubber-based two component systems that can be cold-filled and vulcanise at room temperature.


Siliconrubber-based two component systems for very special and High-tech applications. These compounds are also in a compressible form available.
