There are several reasons to use concrete Soil Cell. Although the cement industry is one of the main producers of carbon dioxide. The RootBox concrete soil cell systems is fully circular. Easy to dismantle without damaging the integrity of the system and reuse somewhere else in the same application.  And there for high on the ranking of sustainability. Depending on the priority given to each value with regard to sustainability, a concrete or a polymer Soil Cell is the more sustainable. Secondly, for all concrete structures there are standard norms with which the structural strengths can be calculated, which are described in various worldwide accepted standards. With polymer materials, these cannot be indicated by calculation methods, instead with polymer soil cell systems, practical tests are carried out to determine the strength.  To help all our customers, we have also developed a circular Soil Cell that consists entirely of concrete and does not require any polymers for proper application.
