I am assuming that these 'paalmassieven' are 'pile caps' (nice picture here:

See also:
'In the British Standard Code of Practice BS 8004, a ground beam is defined as a beam in a substructure transmitting load(s) to a pile, pad or other foundation. The ground beam connects the two pile caps.' +
'(...) the function of a ground beam is to connect adjacent pile caps to ensure stability of the foundation and to ensure stability against lateral forces.
• Ground beams are designed to connect a group of pile caps* in a continuous manner.' (

* See: 'De paalmassieven worden, indien nodig, onderling verbonden door funderingsbalken' from my text.
Also useful info re. use of the term 'massief/massieven':
'funderingsmassief' = 'foundation block' (via: massif de fondation / bloc de fondation / foundation mass)(Termium plus))
