RockSolid carried out studies of the underground in the fuel depots of Logistique Pétrolière SA (LPSA) located in Maintirano, Antalaha, Maroantsetra, Antsahampano and Nosy-Be. The aim of the surveys was to identify the underground structure with a view to installing groundwater observation wells at each site. The piezometers were then installed by BushProof Sàrl.
