Ottawa-based wastewater treatment systems maker Clearford Industries Inc. completes due diligence preliminary to its planned $22-million buy of an unspecified concrete manufacturer headquartered in Ontario. Clearford has formed a committee of its board members to review the terms of the deal, and expects to sign a definitive purchase agreement for all shares of the vendor's company by April 15. "The addition of the vendor's business to Clearford's concrete division builds on Clearford's strategy of consolidation of the wet cast segment of the pre-cast concrete market through acquisition," says the company. Clearford, which made a conditional offer for the business last November, is currently putting together financing for the acquisition, before seeking shareholder and board approval.
