The patented soundproofing system for manholes and drains

The smart solution for a better life

If you’re here, it’s because there’s a loud manhole that’s making your life impossible.


Try NOISE-STOP®: the only product made of special rubber, which reduces the noise caused by the tilting of manholes and storm drains. Suitable for any shape, it helps to compensate for defects between lids and frames, reducing the annoying noise that both produce for the stress of traffic that flows over them.

NOISE-STOP® is available in three variants, for each type of manholes

Each NOISE-STOP® kit consists of three series. They adapt to the different wear and traffic conditions in which the manholes or storm drains are placed. Designed to resolve noise from the most residential areas to those of the most intense traffic.
In addition, thanks to its versatile shape, Noise-Stop warn. can be applied to all round, square or triangular manholes or manholes.


Choose the variant that best suits the characteristics and dimensions of the noisy manhole.


How NOISE-STOP® works

When a vehicle passes over a manhole cover, it most often causes the annoying metallic noise well known as kling-klong.
This noise is due to the contact of the two main parts of the manhole: the frame and the cover.

NOISE-STOP® is the solution: each kit consists of at least 4 units that, once applied between the cover and the manhole frame or storm drain, compensate for the shimming between the two parts, effectively reducing noise.

I received the product and installed it and indeed there was a significant reduction of noise ?. One of the drain covers was a little bit bent and looser on its frame than the other drain covers, so I used more than just four gaskets and also fastened it to its neighbors with cable ties. Overall the noise level is much lower and less noticeable than before and I’m very happy to have purchased this product!
