CSG would acquire a further 49% in both Significant Site Services South Africa and Significant Site Services Mozambique.
The companies build and maintain remote site villages with the main focus being on the management of the facilities.
CSG‚ which was recently formed by the merger of workforce manager M&S Holdings and contract services specialist BDM Holdings‚ said it believed the integration would be seamless.
It already held 41.28% in each of the two firms. The deal would be settled in cash and shares.
