In 1914, Claridge's Company entered into a joint venture to produce tar-bound macadam, with materials manufactured through a subsidiary company called <answer>Clarmac</answer> Roads Ltd. Two products resulted, namely <answer>Clarmac</answer>, and Clarphalte, with the former being manufactured by <answer>Clarmac</answer> Roads and the latter by Claridge's Patent Asphalte Co., although <answer>Clarmac</answer> was more widely used.[note 1] However, the First World War impacted financially on the <answer>Clarmac</answer> Company, which entered into liquidation in 1915. The failure of <answer>Clarmac</answer> Roads Ltd had a flow-on effect to Claridge's Company, which was itself compulsorily wound up, ceasing operations in 1917, having invested a substantial amount of funds into the new venture, both at the outset, and in a subsequent attempt to save the <answer>Clarmac</answer> Company.
