The administrator Tom Keenan, of Keenan CF, confirmed the development on Friday morning.
He said that the staff will be made redundant with immediate effect.
A statement read: "A significant number of customers have terminated contacts resulting in a sharp decline in activity levels. The company's trading position will continue to be reviewed."
Earlier this month, 190 jobs were lost at the firm due to difficult trading conditions.
North Antrim MP Ian Paisley sent his condolences to staff at one of the oldest and most established firms in Ballymena.
"I will do anything in my power to help those so tragically affected by this loss.
"A long road is ahead, and we will all do our utmost to limit the negative impacts on the town of Ballymena and our people," he commented.
As each day goes on in this travesty, the heartbreaking news is not any easier to take, and with Christmas right around the corner my thoughts and prayers are most certainly with all involved.
Sinn Féin MLA Daithí McKay said the latest job losses were "especially cruel given that we are now only weeks away from Christmas.
"The Department of Employment and Learning must ensure that they can do whatever they can to support those redundant workers and help them fit back into the workforce elsewhere," the north Antrim politician said.
UUP chief whip Robin Swann said his constituents were still reeling from the jobs loss announcement only a few weeks ago.
"This now means that 244 out of the 320 jobs at the Patton's Group are gone and the devastation is being felt right throughout the community. My immediate thoughts are again with the individuals affected as well as their families.
"What is now important is that the relevant Ministers - Arlene Foster in Enterprise and Sammy Wilson in Finance, begin to look at their options in order to offer real support to the construction industry," he added.
Mr Swann said that the future of sub-contractors' businesses could also be threatened.
"The Enterprise Minister must outline the full scale of the effect which the job losses will have on suppliers and traders.
"We must look at how we can improve processes to offer greater protection to subcontractors and to ensure prompt payment," he concluded.
Alliance Councillor Jayne Dunlop has described the news as "another devastating blow."
"It is a very sad time for all involved in this company," she said.
"It is having a knock on effect on shops and businesses in the area as I know some people have cancelled large orders as they are uncertain of their economic future," the Ballymena politician added.
"I hope that the Executive will do all that is possible to help Patton as well as the construction sector in general which is facing a difficult time."
