Our soil testing services include:


Construction testing

Tests for existing soil structure/properties and materials. Consequently this helps us select quality soils, sands and materials for the construction of your sports turf.



Particle size analysis


Particle size analysis

We provide a particle size analysis for sands and aggregates. This is especially relevant as it can be used to approve or suggest modifications to your materials.


Organic matter content

Our analysis provides you with percentage concentration within the soil’s profile. This analysis determines whether there is a need for you to reduce organic matter to enhance the playing qualities of your sports turf.
