Water Filter Gravel
In Spain

We are among the leading manufacturers and suppliers of water filtration gravel and pebbles in Spain.

Our filtration gravel is naturally hard, rounded to sub rounded and predominantly quartz aggregate. The gravel is thoroughly washed and screened into various sizes and grades as required by the client.

It is quite similar to Filter Sand in properties, but the only difference is its shape. These are free from calcium and are very effective in the case of softeners, as this helps in maintaining the quality. Support gravel acts as a support for the filter media and forms the lower levels of the filter bed.

Free of organic impurities
