Our interground-Baum substrate mixtures meet the requirements of plant pit construction methods 1 and 2 of the German FLL (Forschungsgesellschaft Landschaftsentwicklung, Landschaftsbau e.V.) and offer optimal conditions:
The FLL "Green Roof Guidelines - Guidelines for the Planning, Construction, and Maintenance of Green Roofs" were developed from the "Principles for Green Roofing" published in 1982 and have been revised several times since 1990. They are recognized as a benchmark set of guidelines for green roofs in Germany.
Even at school, every child learns that trees provide good healthy air. Because of the current discussions about the formation of fine dust and the climatic conditions in cities, this is more topical than ever. Trees have many positive characteristics and play an essential role in residential areas and landscaping:
Trees make a significant contribution to a positive landscape image and contribute to spatial design, especially in urban areas. Trees form a balancing pole in urban development and serve as optical shielding and upgrading and, also, to protect the road against slipping or wash-out.
Trees reduce air pollutants, fine dust, reduce CO2 by storing it in wood, and release oxygen.
Trees regulate the climate by providing a balancing temperature in the summer months, providing shade, reducing solar radiation, lowering wind speed, and reducing noise.
Trees also make a positive contribution to a balanced water balance, as the infiltration of rainwater is improved.
Therefore, we must plant trees in our surroundings to benefit from the positive effects in the future.
When planting trees, it must be noted that they are often not adequately planted and maintained only to fulfil their task. Trees are also complex creatures. They can only achieve their functions if they are healthy and vital.
Therefore, there are some things to consider, especially in urban environments.
As a result, the trees often lose their stability and walkways and roads.
iNTERBiMS GmbH produces mineral / organic tree substrates for trees. Thanks to the open-pored structure, high treading and storage stability, high frost resistance, and the balanced ratio between water permeability and storage capacity, individual substrate requirements are fulfilled "par excellence" even in deep layers.
INTERBIMS offers individual mixtures as well as delivery to the construction site.
Tree substrates contribute to the sustained growth and growth of trees and promote their air and water balance. Our tree substrates consist of mineral substrates with small amounts of organic matter.
interground-Baum substrates are available in several variants, following the construction methods in the FLL (Forschungsgesellschaft Landschaftsentwicklung, Landschaftsbau e.V.) recommendations for plant pit construction methods and substrates.
The Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau e.V. (Research Society for Landscape Development, Landscaping) has drawn up recommendations for tree planting in 2 parts, which are generally accepted.
In the "Recommendations for Tree Plantings - Part 1: Planning, Planting, Maintenance", sustainable guidelines are defined for tree plantings, from planning to achieving the intended functions.
In the "Recommendations for Tree Plantations - Part 2: Site Preparations for Tree Plantations; Planting Pits and Root Zone Expansion, Construction Methods and Substrates", minimum requirements are defined for this purpose, especially for tree plantations on traffic areas and in populated areas, if the existing soil is not suitable for the intended plants and uses.
The recommendations of the FLL, therefore, distinguish between the following two areas of application:
Tree substrates for open, uncovered planting pits (planting pit construction 1), whose surface is only slightly stressed.
Tree substrates for covered plant pits (plant pit construction 2), whereby the plant pit backfilling is the plant location and the building ground for the traffic areas.
The requirements for a permanently stable soil skeleton are high since the substrate must serve the tree for a long time. interground-Baum substrates forever ensure the necessary air and water balance. With proper structural stability, a larger pore volume is provided even in deep layers.
These are characterized as follows:
iNTERBiMS offers individual tree substrates and their delivery to the construction site in all common delivery forms:
Tree Substrate 0-16
Tree Substrate 0-32
Other forms of delivery are on request.
All products are subject to quality control (external and internal monitoring) following the German FLL guidelines.
