Type of Soil

Soil Description

Product Recommendation

Topsoil, first layer of soil which contains non-organic substances as well as humus and organisms found in soil.

Type 1

Flowing or soft types, from liquid to viscous texture, which make it difficult to get rid of the water.

Type 2

Easily soluble soil types, from non- to low-cohesive sand, gravel and sand-gravel mixtures with up to 15% of the weight from mixtures of silt and clay and a maximum of 30% of the weight coming from stones with a grain size over 63mm and with a volume of up to 0.01m². Organic soils with a consistency better than pulp or peat.

Type 3

Moderately soluble soil types; with a share of more than 15%  of the weight from mixtures of sand, gravel, silt, and clay; cohesive soils of low to medium plasticity; at the most 30% of the weight consisting of larger rocks with a grain size over 63mm and with a volume of up to 0.01m².

Type 4

Soil types that are tough to penetrate; similar soil according to the soil classification 3 and 4, but with more than 30% of the weight from stones larger with a grain size over 63mm grain and with a volume of up to 0.01m². Similarly, non-cohesive to cohesive soils with more than 30% of the weight from stones with a volume between 0.01m² to 0.1m² and distinctive plastic clays that are soft to firm, depending on the water content.

Type 5

Rocks which have an inner mineral bound cohesion, but are strongly crevassed, brittle, crumbly, slated, soft or weathered as well as comparably solidified cohesive and non-cohesive soils, such as those caused by drying, freezing or chemical bonds; non-cohesive and cohesive soils with more than 30% of the weight from the rocks with a volume over 0.01m² to 0.1m².

Type 6

Difficult to penetrate rock, rock type that has an inner mineral-bound cohesion and high structural strength and are only slightly creased or weathered. Boulders, firm non-weathered minerals/clay shale, mountainous rock chain, slag heaps from melting works, etc.
