TzaneenLab
is Now
SoilPro
A trusted civil materials testing laboratory for South Africa's construction and engineering industries.
SANAS-accredited testing facility operating to ISO/IEC 17025 and recognised under the ILAC Mutual Recognition Arrangement. All methods executed to SANS / TMH standards for assured technical integrity.
Built on Experience.
Reimagined for the Future.
Since 1989, Tzaneen Lab has performed civil engineering, geotechnical investigations and material testing across a wide spectrum of civil engineering and construction projects · from regional road networks and bulk earthworks to structural concrete and large-scale developments.
Today, that legacy carries forward as SOILPRO · a refined identity that better represents our commitment to precision, innovation and the evolving needs of the civil engineering and construction industries.
While our name is changing, our commitment to reliable testing, technical excellence and trusted partnerships remains the same.
