SAN FRANCISCO (CBS SF)– Cemex, an international building materials supplier, has donated 20 tons of sand to refill the sandbox at Mission Dolores Park in San Francisco, city Recreation and Parks Department officials announced this afternoon.

Rec and Parks crews had to empty the sandbox in the Helen Diller Playground after vandals smashed beer bottles against its concrete walls on Feb. 19. The sandbox wasn’t safe to play in until all that material was cleared and replaced, according to city officials.

Sara Engdahl, a spokeswoman for Cemex USA, said in a prepared statement that it was “a real pleasure” to help reopen the playground.

Cemex was founded in Mexico in 1906, according to the company’s website.
