The ice on a rink at the Mount Pearl Glacier sports facility melted during last week's power outage, and it's taken six days for workers rebuild it from scratch.

Glacier manager Michelle Rideout said the building was without power for 18 straight hours during last week's blizzard, and once the ice started melting nothing could be done to save it.

Since then, up to a dozen workers have been toiling around the clock to restore the ice surface.

Maintenance supervisor Darren Blundon said it had to be rebuilt to a thickness of about 3.5 centimetres.

"It takes a lot of water, a lot of time, and we have to build it in layers."

Blundon added that the process involved more that just re-flooding the space.

"You have to remove the ice from the floor. Obviously it don't all turn to water, then you have to use some type of means to push it out of the building," said Blundon.

"And we have to clean and scrub the floor and pull the temperature back down to a certain temperature and then start building the ice back and do your painting (of the ice) and so on and so forth."

The rink reopened for business at 4 p.m. today.
