One of the surviving farmsteads bears the name "Het Dalemhof", of which the middle syllable is thought to derive from the Germanic word "heim", endorsing the view that the name is of Frankish provenance.

By the late medieval period Korbeek-Lo was an agricultural village, with a handful of substantial farmsteads owned by monasteries, charitable institutions or wealthy citizens from nearby Leuven/Louvain.

The end of the medieval period was a time of suffering, notably at the hands of Emperor Maximillian (1488-1489) and during the Siege of Louvain by Maarten van Rossum in 1542, and again during the religious wars of the late sixteenth century, the campaigning following the creation of the Franco-Dutch alliance of 1635 and again the French invasion of 1695.

In 1914, 24 and 25 August saw central Louvain/Leuven set alight, and during the ensuring days it was the turn of the villages along the road towards Tienen to suffer similar assaults.

By the end of the nineteenth century the van 'De Mol' quarter also contained several small brick works, but these had all ceased to operate.

A modern motorway, the A3/E40, of which the local section opened in 1972,[1] parallels to the older National Road 3, but is positioned a couple of kilometers to the south and therefore a short distance away from the centre of the village.
