Index Tests
Index testing undertaken by ESG is generally used for classification of materials, profiling and derivation of parameters for subsequent advance testing. These tests include:
- Moisture content
- Atterberg Limits
- Density (Bulk, dry and limiting)
- Particle Size Distribution (PSD)
- Particle Density (Small pyknometer and Gas jar)
- Shrinkage
| Test Type | Fine | Medium | Coarse |
|---|---|---|---|
| Moisture content | 50g | 350g | 4kg |
| Atterberg Limits (LL/PL) | 500g | 1kg | 2kg |
| Density (Linear) | 500g | 1kg | 2kg |
| Particle Size Distribution (PSD) | 150g | 3kg | 17kg |
| Particle Density (Small pyknometer) | 100g | 100g | na |
| Particle Density (Gas jar) | 1kg | 2kg | 4kg |

Testimonials
ESG through its Soil Mechanics brand were set a tough challenge by RWE npower and met it full on. From the engineer's perspective, it was evident from the start that many parts of the business would need to pull together to achieve the client's demanding programme. Pembroke in November was never going to be easy, but staff on site, in Bridgend and in the labs demonstrated a team commitment to match and on occasions exceed the client's expectations.
