More than 200 tonnes of grout have been used to fill the hole that appeared behind Howbank Road in Egremont on 14th November.
Contractors Forkers will be back at the site on Monday (7th January) to put in place a permanent cap.
The work should be finished by 18th January, before work begins to landscape the area and reinstate the fields and gardens damaged when the hole appeared.
Copeland Borough Council who own the land say the grout column should stabilise the hole and keep the homes near the hole safe.
Those living in the nine homes affected were allowed back home on 21st December although some have chosen not to return.
