Mannington Mills Inc. recently began work on a $3.4 million, 100,000 square-foot warehouse as part of an expansion of its wood and laminate facility operations in High Point, N.C. Renovations are also under way at Mannington's main factory.

The expansion projects are expected to add 418,000 square feet of space and allow the company to step up production in wood and laminate, as well as vinyl and ceramic tile.
