Foundation for 100 homes “Josefines Garden”

Sub base compensation

Project name Foundation for 100 homes “Josefines Garden” Volume 6.000 m³ expanded clay 10-20 mm Location Løkken , Denmark Year 2008
Contractor Kaa Gruppen A/S Designer Andreasen & Hvidberg K/S Owner/Builder Kaa Gruppen A/S


100 new homes were to be build. The construction site is the “ old “ Josefines Camping located directly to the North Sea.  The Geotechnical report showed very soft sub soil which created a need for either soil reinforcement or reducing the loads.

Why Expanded Clay:

The competing solutions were piling or drilled foundations. The lightweight filling method was used because it gave less or no inconvenience for the neighbours and was  financially more attractive.


Load compensation calculation showed that 75 cm of expanded clay 10-20 mm could completely compensate the load of the buildings. Around 60 m3 for each home.  Furthermore any contractor can make this kind of construction and it does not imply special piling or drilling equipment. The workers that erected the houses liked the flat and dry construction site.
