The most critical growth condition for urban trees is access to sufficient quantities of uncompressed soil.

For 20 years, skilled and farsighted experts have employed the most modern structural soil cell system. By using soil cells instead of traditional compacted structural soil mixes it is possible to achieve three times the volume of soil within the same area, together with a root growth zone of uncompacted soils. As well as this, use of soil cells systems minimizes the risk of incorrect construction of the tree pit to a minimum.
