Terrier Drills to 45 Metres in Costa Rica
Dando has recently received some more great feedback from Costa Rican customer MYV about their Dando Terrier, purchased in 2007.
Their latest project saw the compact site investigation rig drill two boreholes to 45m deep, coring with T2-76 through mud and volcanic sands. Pressure meter tests were also carried out, with pressure limits of 4000 Kpa achieved at 35 metres deep. Core photos and images of the drilling process and PMTs can be viewed in the gallery below. *Please note: These photos were taken by the customer in Costa Rica where H & S requirements differ from those in the UK.
