Dynamic Sampling

Geo Environmental Engineering specialises in dynamic sampling with windowless and window sampling rigs, with dynamic probe and diamond coring capabilities detailed below:

• Windowless sampling (soil samples are recovered in plastic liners) up to 10 metres depth can be achieved using a tracked Dart/Competitor style rig.
• Dynamic probing up to 20 metres deep to BS1377:1990.
• SPT’s (Soil penetration testing using open drive shoe) & SPT(C) (Solid Cone) for sand/gravel strata.
• Hand Held sampling for low head room or confined areas where access for the tracked rig is not possible using a hydraulic hammer to drive the samples into the strata.
• 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.
• Hand dug trial pits to expose footings, utilities etc.
• Water/gas well installations for long term monitoring.
• SVS Surveys (soil vapour surveys) to determine gas presence before drilling on Petroleum service stations etc.
• NVQ Level 2 Drillers experienced in logging to BS5930 and Eurocode 7.

Cable Percussion Drilling

Geo Environmental Engineering can undertake cable percussion drilling detailed below:

• 150mm and 200mm diameter boring to depths of c.50m below current ground levels.
• Insitu testing to include SPT’s and CPT’s.
  
• Insitu sampling to include geotechnical (U100) and contamination (Amber Glass Jars) related sample recovery.
