Friday, July 22nd, 2005 — Contractors attempting to rebuild buildings and homes destroyed last year by Hurricane Ivan and this month by Hurricane Dennis, claim their inability to complete repairs is due to a lack of labor while homeowners claim there is also a shortage of materials. While there’s now an adequate supply of most materials, cement remains the big exception. The shortage is delaying some projects by two months or or more and is blamed on a U.S. embargo on Mexican cement.
