Compaction and a build-up of water are the two most frequent reasons leading to the time-consuming renovation of tree roots.
If the oxygen content in the soil falls below 13%, the roots can no longer grow. Many trees die or guide their roots upwards where they force out kerb stones and transform paving slabs into trip hazards.

The use of the RSP suction excavator enables the whole root system to be exposed gently and without damage while also saving time. It is helpful with very heavy soils to use a compressed air lance. This forces open the solid top layer of soil while protecting the roots, which makes it easier and faster to extract the soil. For many towns and communities, an environmentally friendly replanting and replacement of contaminated soil using a suction excavator is of the utmost importance.
