RONDO sealing collars
Safe, versatile and tested to the highest standards
In contrast to many of their competitors, our RONDO sealing collars have been tested by independent bodies under real-life conditions to the highest standards - most recently for their suitability for corrugated pipes. All tests have repeatedly confirmed the safety of our RONDOs.
Our RONDOs offer reliable waterproofing of pipe ducts through concrete components against pressurised water and - depending on the type - also against gases such as methane and radon gas, which is sometimes present in the ground. Our sealing collars are particularly secure thanks to the fastening straps supplied, which, once tightened, guarantee the permanent sealing of the pipe duct.
Especially in comparison to sealing collars that are only pushed on, the universal application options and the superior safety of the RONDOs are evident:
