Whenever a soil or concrete report lands on a municipality desk or a consultant's table in Saudi Arabia, the first question asked is the same: is the laboratory accredited? As of June 28, 2026, our answer is officially documented — the Saudi Accreditation Center (SAAC) has granted TECHNO Soil Lab Company for Testing, Soil and Physical Analysis accreditation certificate No. N-T-00645 under ISO/IEC 17025:2017, the international standard governing the competence of testing and calibration laboratories.
The scope covers our core field and laboratory services — soil testing, concrete testing, asphalt testing and aggregate analysis — across every branch in Makkah, Jeddah, Madinah, Riyadh and Qassim, formally placing us among the accredited soil testing laboratories of Saudi Arabia.
The Certificate at a Glance
Why ISO/IEC 17025 Outranks a Regular ISO Certificate
Many firms hold ISO 9001 for their management system. ISO/IEC 17025:2017 goes considerably further: assessors verify a laboratory's actual technical competence in the field — instrument calibration records, technician qualifications, how each test method is executed, and how measurement uncertainty is calculated. That is precisely why Saudi municipalities, the Ministry of Municipalities and Housing, and most government bodies insist that soil and concrete reports come from a laboratory accredited to this specific standard.
SAAC is the Kingdom's sole national accreditation body, and its full membership in the ILAC Mutual Recognition Arrangement means any certificate it issues is automatically recognized in more than 100 countries.
The Five Tests in Our Accredited Scope
Accreditation was granted for five tests that form the backbone of any construction QC program:
- Modified Proctor compaction per ASTM D1557 — the reference for earthworks and fill layers. More on soil testing
- Sieve analysis of fine and coarse aggregates per ASTM C136/C136M — the acceptance gate for any aggregate entering a mix.
- Atterberg limits (liquid limit, plastic limit, plasticity index) per ASTM D4318 — classifying fine soils and their moisture behavior.
- Compressive strength of cylindrical concrete specimens per ASTM C39/C39M — the decisive test in on-site concrete quality control.
- Theoretical maximum specific gravity of asphalt mixtures per ASTM D2041/D2041M — the basis for air-void calculations in asphalt testing.
What Your Project Gains in Practice
- Direct government acceptance: our soil, concrete and asphalt reports are accepted by municipalities and housing authorities with no extra conditions.
- Legal and financial weight: accredited reports hold up before courts, banks and real-estate developers in disputes or financing files.
- Cross-border recognition: through ILAC-MRA, our reports serve projects with international specifications and foreign contractors.
- Scientifically controlled results: every figure passes a documented internal QC chain, from instrument calibration to final report review.
The Official Certificate
Watch: A Short Introduction
One Certificate, Every Branch
The accreditation is issued to the company and applies at all locations: Makkah (HQ — Batha Quraysh), Jeddah (Al-Furusiya — coastal and saline soils), Madinah (Al-Awali), Riyadh (Al-Nadwa — development and infrastructure), and Qassim (Buraidah — serving the central and northern regions).
