SAND ON REQUEST & CUSTOM
The sands used by SNL are natural, siliceous for all fractions from the finest (5µm) to the coarsest (16 mm). They are dried, screened and then classified into different selected fractions.
To comply with the specific requests of our customers, the preparation workshop enables re-composition and homogenization in a mixer of different fractions of sands to achieve the requirements (in value and dispersion) set.
EXAMPLES OF SNL PREPARATION
- Reconstituted and coloured sand of the riverbed (study of stream flows and floods and dam release study).
- Neutral substrates for mesosoma environmental studies.
- Sands with granulometries and colours adapted to study for simulation of avalanches.
- Reconstructed sands with a chosen porosity in place.
- Sand of selected and statistically validated grain size to verify laboratory sieves.
- Quartz stripping sands for cleaning laboratory grinders.
- Sand following EN 168 (wear on glasses)

CONTROLS
Granulometry, weight, humidity or any other test, if necessary, are carried out in the SNL laboratory.
PACKAGING
The sand packaging can be made in small bags, calibrated in weight or in bulk in bags ranging from 0,3kg to 25 kg; other packaging can be considered upon request.
These products are then put on pallets and sent around the world.
