Chemical Analysis in Qassim
Comprehensive chemical analysis for drinking water, wastewater, groundwater, and irrigation water, plus agricultural soil and aggregate — pH, turbidity, total hardness, calcium, magnesium, sulfates, chlorides, and TDS.
Chemical analysis of soil and water is a laboratory test measuring pH, chlorides, sulfates, and total dissolved solids (TDS) to determine a site's aggressiveness toward concrete and rebar. Performed by an accredited lab per ASTM and Saudi Building Code SBC 303, it determines the required cement type and protection before foundation work in areas with saline soil or groundwater.
What Is Chemical Analysis of Soil and Water and Why Does It Matter Before Foundation Work?
Chemical analysis is a laboratory test measuring the content of salts and chemical compounds in soil, water, or aggregate that affect construction materials. It includes pH measurement, chloride content that accelerates rebar corrosion, and sulfate content that reacts with cement, causing concrete expansion and deterioration over time.
Undetected aggressive soil can destroy a building's foundation from within with no visible signs for years. Early detection of high sulfate or chloride levels allows the engineer to select resistant cement or apply appropriate waterproofing before pouring — rather than remediating damage after it appears.
As a laboratory accredited to ISO/IEC 17025:2017 (SAAC accreditation No. N-T-00645) and approved by MODON, Asas Lab performs chemical analysis of soil, water, and aggregate in Makkah, Jeddah, Madinah, Riyadh, and Qassim, issuing certified reports that support structural design decisions.

Chemical analysis — Water & Soil (pH, Chlorides, Sulfates, TDS)
التحليل الكيميائي للمياه والتربة (pH، كلوريدات، كبريتات، TDS)
Chemically analyzes water and soil samples for pH, chlorides, sulfates, and total dissolved solids (TDS) — determines site aggressiveness toward concrete and rebar.
Unit: sample
Chemical analysis — Aggregate (pH, Chlorides, Sulfates, TDS)
التحليل الكيميائي للركام (pH، كلوريدات، كبريتات، TDS)
Chemically analyzes aggregate for chlorides, sulfates and dissolved salts — verifies the aggregate is free of contaminants that could weaken concrete bonding or accelerate rebar corrosion.
Unit: sample
Turbidity Measurement
قياس العكارة (Turbidity)
Measures water turbidity (drinking water, sewage, groundwater) — a key indicator of water clarity and suitability for household and hotel use.
Unit: NTU
Total Hardness
العسرة الكلية (Total Hardness)
Measures total water hardness from calcium and magnesium salts — relevant for drinking water, hotel use (boilers and plumbing), and agricultural irrigation water.
Unit: mg/L CaCO₃
Calcium
الكالسيوم (Calcium)
Measures dissolved calcium concentration in water — a component of total hardness and an important indicator for drinking and irrigation water.
Unit: mg/L
Magnesium
المغنيسيوم (Magnesium)
Measures dissolved magnesium concentration in water — used with calcium to determine total hardness and assess water suitability for drinking and irrigation.
Unit: mg/L
Electrical Conductivity (EC)
التوصيل الكهربائي (EC)
Measures water electrical conductivity to assess dissolved salts alongside TDS — high salt levels cause a salty taste, clog shower heads, and attack stainless-steel water heaters.
Unit: µS/cm
Alkalinity
القلوية (Alkalinity)
Measures water's capacity to resist acidity and protect plumbing and heaters from corrosion — below 50 ppm is highly aggressive and may corrode copper and iron or turn water yellow or blue, 80–150 ppm is ideal for stable pH at 7–8, and above 300 ppm causes heavy white scale in building and hotel heaters and boilers.
Unit: mg/L CaCO₃
Free Residual Chlorine
الكلور الحر المتبقي
Measures free residual chlorine to verify water disinfection — 0 ppm means no disinfection and a Legionella risk in shower steam and heaters, 0.2–0.5 ppm is ideal without odor, and above 1 ppm causes a strong pool smell, eye and skin irritation, and bleaches clothing.
Unit: mg/L
Iron
الحديد (Iron)
Measures iron concentration in water — helps diagnose yellow water and brown stains on white towels in homes and hotels.
Unit: mg/L
Manganese
المنغنيز (Manganese)
Measures manganese concentration in water — helps diagnose black stains in bathtubs across residential and building water systems.
Unit: mg/L
Chemical Analysis of Soil and Water in Qassim — Agricultural Legacy and Construction Chemistry
Qassim's long agricultural history creates unique soil chemistry: decades of irrigation have mobilized and redistributed minerals and salts to deeper layers in converted farm-to-construction sites. ASAS Lab provides sulfate and chloride concentration analysis for BS 8500 aggressiveness classification, electrical conductivity as a total dissolved solids indicator, and nitrate analysis for former agricultural sites with chemical fertilizer history. Detailed recommendations for concrete specification and cement type selection are included with each report.

FAQ About Chemical Analysis
Aggressive soil rich in sulfates or chlorides reacts with cement and steel, causing early structural deterioration. SBC 303 mandates chemical analysis in areas with saline soil or near brackish groundwater.
