Salt-impacted soil: SAR and EC
Road and parking-lot soil often fails on salt alone. Call us with your SAR and EC results before you plan the haul.
What SAR and EC measure
- SAR is the sodium adsorption ratio.
- EC is electrical conductivity.
Both rise where road salt has been used. Soil from road, sidewalk and parking-lot work can meet a table on everything else and still fail on these two.
Where our locations stand
- Meets Table 3.1, salt included. Both locations take it.
- Above Table 3.1 for SAR, EC or metals. Call first with your results.
