Persimmon has offered to take on more than 100 Cuddy Group staff following the administration of the Welsh specialist.
The housebuilder said it would offer all of Cuddy’s groundwork staff new jobs in its business, with workers able to transfer over to the company as early as Tuesday.
Persimmon’s move comes after Cuddy confirmed it had given formal notice of its intention to appoint administrators.
In a statement given to the BBC, Cuddy Group said it had hit trouble after its managing director Mike Cuddy spent six months in hospital and a further 18 months recuperating at home.
The statement said: “During his enforced absence from work at Cuddy Group, he had hoped that others would have stepped up to fill the gap he had left.
“Unfortunately this did not happen and the challenges facing the company increased month on month throughout 2017 and into 2018.”
The statement said that, despite Mr Cuddy injecting personal funds into the firm, there was no alternative left than administration for the group.
Persimmon Homes managing director for east Wales Martin Smith said: “In excess of 100 people could transfer from Cuddy into our business.
“We are meeting with the workers on Monday and, should they wish, they can start with us on Tuesday.
“They will become part of the Persimmon team and we are able to offer good pay and a long-term, stable future.”
In 2014 Persimmon stepped in to recruit 35 staff to its groundworks division from contractor Macob after it collapsed.
