Welcome to Geo Site Surveys

We specialise in windowless soil sampling, cable percussion drilling (shell & auger), dynamic probing, concrete coring/sawing & utility clearance surveys.

GSS offer the following services:

• We can now offer a totally unique electrical powered drilling unit which is capable of windowless sampling, SPT’s etc, the same as a diesel/petrol powered rig - but, (being electric) it does not produce any fumes.
  
  
• Geo Site Surveys have designed and built a windowless sampling rig fitted to a tracked all-terrain specialist light weight vehicle.
  
  
• Windowless sampling (soil samples are recovered in plastic liners) up to 10 metres depth can be achieved using a tracked archway dart rig.
  
  
• Dynamic probing up to 15 metres deep to BS1377:1990
  
  
• SPT’S (soil penetration testing using open drive shoe) & SPT(C) (solid cone) for sand/gravels.
  
  
• Hand Held sampling for low head room or confined areas were the tracked rig will not fit. Using a hydraulic hammer to drive the samples into the strata.
  
  
• Cable percussive drilling (Shell & Auger) 6 & 8 inch drilling either open holed or cased drilling up to 40 metres.
  
  
• Rotary drilling using a small tracked rig (900mm wide) suitable for restricted access sites. Capable of open hole/coring up tp 40 metre deep using water/air or mist flush.
  
  
• Concrete coring off the rig for drilling on hard standing.
  
  
• Stand alone diamond coring unit (electric powered) for hole up to 350mm diameters & to a depth of 1.5metres.
  
  
• Wall coring to determine the thickness and condition on bridges, pylons etc.
  
  
• Wall chasing, floor sawing, open cut and break out in concrete, brick, block etc.
  
  
• Hand dug trial pits to expose footings, utilities etc.
  
  
• Utility underground surveys prior to drilling/coring or to determine were the services are located.
  
  
• GPR (ground probing radar) to determine plastic services ie. water, gas pipes etc.
  
  
• Water/gas well installations for on going monitoring.
  
  
• SVS Surveys (soil vapour surveys) to determine gas presence before drilling on Petroleum service stations etc.
  
  

GSS can offer either a single day’s soil sampling (on day rates) or a fixed/term rate for medium to larger size projects.
