TARMAC businesses that cannot win a major market share face being sold off.
The sales form part of a review by Tarmac's owner, Anglo American, which has run the rule over its mining and materials operations.
Ta rmac ch ief executive Robbie Robertson said: 'We like to have a critical mass or a market-leading position in local markets. Bits of the portfolio may be for sale if they do not pass this test.
'We're examining the products that are performing well and whether they have a competitive advantage.
'We've sold businesses in the past, like the brick business. This is an ongoing process and Anglo American is very supportive.' Tarmac turns over £2 billion a year and sold brick subsidiary Wilnecote to Hanson in November 2004 for an undisclosed fee.
Mr Robertson did not identify any businesses facing disposal but said he would be 'very surprised' if Tarmac's road surfacing operation was sold as a result of the review.
