Expanded silicate granulate
The volcanoes of the Eifel became extinct about 12,000 years ago. Below the surface around the volcanoes is now an air pore rich, pebble-like mineral made of pure siliceous raw materials – known as natural expanded silicate. After the mining and product enhancement the ecologically excellent raw material is turned into a innovative lightweight aggregate and an ecologically precious substrate.
Characteristics of expanded silicate
- natural and draining material
- long-term soil improvement
- water storage
- nutrient storage
- soil aeration
- positive changes in soil physics
Application areas of BISOROCK Edelbims® and BISOROCK® Siebbims
- soil conditioner
- Aggregate for substrates
- Aggregate for the production of lightweight concrete
Suggestion: use of pumice in grass seed
The optimum soil conditions for grass seeds and the healthy growth of the lawn from there on are very rarely available. For an optimal lawn sowing and a beautiful lawn it is often necessary to analyze the soil conditions with requisite subsequent improvements necessary. The aggregates of the BISOROCK® series will help to improve your existing soil conditions for a sustainably beautiful lawn. The aggregates of BISOROCK® series help to improve the existing soil conditions in relation to water supply, ventilation and storage capacity for nutrients. In this digression, we would like to briefly explain the different soil conditions for a lawn:
The optimum soil conditions for a lasting healthy lawn consist of a loamy sand soil with sufficient organic matter content. They consist of 50% solids, 30% water-filled and 20% air-filled pores. They are hardy and able to retain water and nutrients.
Sandy soils of up to 80% coarse sand and 20% humus-containing soil, by contrast, are used for heavy-duty lawns, such as sports fields. They are extremely durable, because the soil is not compacted. The soil can neither hold water nor nutrients and must be regularly watered and fertilized.
Clay soils are less suitable as a base for turf. While they dry slowly, they then become very hard and tear open. Additionally, clay soils are prone to becoming waterlogged, that can lead to moss instead of lawn.
Humus soils have the disadvantage that the lawn is soft and inaccessible.
