According to DIN18300, the following soil classes have the given swell factors.
Soil class Description
1 Topsoil containing unorganic material, as well
as humus or organic animals.
2 Fluent soil types of fluid to semi-fluid consis-
tency.
3 Easily degradable soil types. Cohesionless to
hardly cohesive sands.
4 Moderately degradable soil types. Mixture of
sand, silt and clay.
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
6 Rock types that have an inner mineral cohe-
siveness, however are fragmented, slaty, soft
or weathered.
7 Hard to degrade rock types with a strong
inner mineral cohesiveness and minimal frag-
menting or weathering.
Swell factor examples: The values given are approximate only. Values may be
different depending on various soil factors.

Description
Area defined by ground points, calculated by
TIN.
Area defined by breakline points, calculated
by TIN.
Volume as calculated by TIN.
Factor that gives the relationship between
the volume of a material 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.
Volume of the material after excavation from
its original location. DTM-Volume II = DTM-
Volume I x Swell Factor.
Weight in tons per m
field.
Total weight of material after being excava-
ted. Weight = DTM-Volume II x Weight
