Poland is co-hosting the tournament with Ukraine and Tusk has made updating the country's antiquated infrastructure a key priority for his government ahead of the championship.
However, Poland's new national stadium, being built by a Polish-Austrian consortium, and a key highway in the central part of the country being constructed by a Chinese company are behind schedule due to technical faults or problems with financing.
"In both cases, I will propose decisive steps. Everything needs to be in line with the agreements, the law. We have paid deposits, we have penalties stipulated. The Polish state will definitely not lose out on this financially," Tusk said.
"We don't want the builders to delay work trying to extort higher prices from the Polish state," he told reporters during a visit to an industrial site in central Poland.
Poland's National Sports Centre (NCS), which oversees the construction of the stadium, has given the companies building the venue two weeks to fix faulty stairs, leaking stands and other shortcomings on the site.
"Our call for tackling all the glaring deficiencies is the last attempt to discipline the contractor. After these two weeks we have the right to cancel the agreement," said NCS spokeswoman Daria Kulinska.
"The Chinese side promised to catch up with all arrears by May 30, but so far we have seen neither the payments nor received any fresh information," said Mikolaj Karpinski, a spokesman for Poland's infrastructure ministry.
"The highway was supposed to be opened in May 2012, just days before Euro 2012. We appreciate that problems with liquidity on the Chinese side have cost us several precious days, but we still hope we will make it on time," he added.
