No two projects are the same. Sometimes we apply Trisoplast in tight spaces, sometimes on steep slopes and sometimes on very unusual surfaces. The latter was the case when sealing the new outdoor area of recycling company Kruiswerk in Bergambacht. A ground full of piles.

Working on dragline mats

Some soils are more stable than others. The site of Kruiswijk Recycling's new building proved to be very sensitive to subsidence. To counteract this fragility, a grid of piles was laid up to 17 metres deep, with the top protruding above the ground.

Solid: yes. Practical: less so

Arend van de Pol was involved in the project from Trisoplast: 'The application of the Trisoplast, the separation fabric and the concrete floor is done directly on those piles. But because these were not allowed to be loaded sideways, we had to put the machines on dragline mats and drive on them. Waterproofing the Trisoplast against the concrete structures and around the piles was a piece of cake'.

Re-sealing with Trisoplast

A successful workaround, as it turned out, because this part of the outdoor area - covering 8,200 m2 - is completely ready to be used as a storage area for various materials. And the knowledge of applying Trisoplast between piles also came in handy again a few years later, when we sealed a site of similar size with Trisoplast with 'phase 2'.
