The Dutchman, 30, will undergo a medical on Friday before completing a switch from Mallorca to Fratton Park.
Pompey are also close to completing a loan deal for Benfica's 23-year-old Norwegian striker Azar Karadas.
"At the start of our transfer campaign I told you we would be improving every position - including goalkeeper," said Pompey chairman Milan Mandaric.
"Westerweld is an experienced goalkeeper and he spent a couple of years at Liverpool and in Spain.
