Exxaro Secure the Safety of its New Lakeside Towers Development

GeoGroup Companies help Exxaro Secure the Safety of its New Lakeside Towers Development

The New Exxaro’s Lakeside Towers Office Development was developed over a dolomite rock formation. The dolomite formation is renowned for developing sinkholes and this poses a potential risk to the safety of structures built upon them and hence the people within those structures.
