Swell Factor According to DIN18300, the following soil classes have the given swell factors.
Swell factor examples: The values given are approximate only. Values may be
different depending on various soil factors.
Swell Factor Factor that gives the relationship between the volume of a mate-
rial as found in nature, to the volume of the same material after
excavation. Refer to the table "Swell Factor" for more information
on swell factors.
DTM-Volume II Volume of the material after excavation from its original location.
DTM-Volume II = DTM-Volume I x Swell Factor.
Weight Factor
Weight in tons per m
3
of material. Editable field.
Weight Total weight of material after being excavated. Weight = DTM-
Volume II x Weight Factor.
Field Description
Soil class Description Swell Factor
1 Topsoil containing unorganic material, as well as humus
or organic animals.
1.10 - 1.37
2 Fluent soil types of fluid to semi-fluid consistency. n/a
3 Easily degradable soil types. Cohesionless to hardly
cohesive sands.
1.06 - 1.32
4 Moderately degradable soil types. Mixture of sand, silt
and clay.
1.05 - 1.45
5 Hard to degrade soil types. Same soil types as classes 3
and 4, but with a greater ratio of stones bigger than
63mm and between 0.01 m
3
to 0.1 m
3
in volume.
1.19 - 1.59
6 Rock types that have an inner mineral cohesiveness,
however are fragmented, slaty, soft or weathered.
1.25 - 1.75
7 Hard to degrade rock types with a strong inner mineral
cohesiveness and minimal fragmenting or weathering.
1.30 - 2.00
