Turning old into new: 
KERA.Port inspection shaft is excavated again after 7 years of intensive use

Pilot project in The Netherlands

In the Dutch municipality of Buren, a ceramic inspection pit is being excavated again after 7 years of use. The residential development Oosterweyden Maurik is expanding, and as a result, the KERA.Port end pit is being replaced with a new KERA.Port featuring an additional connection. But what does the pit look like after 7 years of intensive use?

KERA.Port – the corrosion-resistant inspection manhole

It almost never happens. But in the residential development Oosterweyden Maurik, in the Dutch municipality of Buren, an installed KERA.Port inspection manhole is being replaced. “Even though the KERA.Port inspection manhole is extremely robust, I was still curious to see what it would look like after serving as an end manhole for 7 years,” says Wil Houben – Account Manager at Steinzeug-Keramo The Netherlands. The KERA.Port inspection manhole stands out from other inspection pits due to its robustness and exceptional chemical and corrosion resistance.

If the tests from our lab yield positive results and meet the required standards, the manhole will be given a second life in this pilot project

Meeting the highest standards

After dozens of minutes of digging, the KERA.Port end manhole emerged from the ground looking as good as new. But what now?

Wil Houben explains: “First, a new KERA.Port end manhole with an additional connection will be installed at this site. Then, we’ll take the old KERA.Port inspection manhole back to our factory in Hasselt. Normally, we would crush the manhole into a new raw material, which would then be used to produce a new manhole.”

“This pilot project is different,” Wil continues. “When the manhole arrives in Hasselt, our lab will inspect it and carry out further tests. If these tests yield positive results and meet the required standards, the manhole will be given a second life in this pilot project.”
