Familiarity with characteristics material
Sometimes everything goes well, but often it goes wrong. Trees that do not grow well en healthy or are drooping for years, to die in the end. Then try to find out what the cause is, if all plants diseases are out of the question. After research of one of the employees of RHP / RAG it appears that the problem has been caused by the use of qualitatively worse soil- and/or structure improvers. Sometimes the cause is the tree soil, which is unsuitable for a certain application, through which the roots of a tree are getting too wet or too dry. Sometimes the cause is the use of insufficient stable compost, which causes an low-oxygen circumstances in the roots. That's why it is essential to start from materials which are classified under RAG Landscaping.

RAG Landscaping supplies extra deepening and goes beyond the RAW-guide lines, drawn up by CROW (the knowledge centre for traffic, transport and infrastructure).

• Meet the legal requirements concerning contaminations with heavy metals, PAK's and mineral oils.
• Lack the most occurring quarantine diseases guaranteed.
• Lack weeds.

RAG guarantees a dynamic quality mark that follows the practical developments and developes research methods in order to support these.
