Percolation and Permeability Tests: Determining how quickly water drains through soil, which is critical for drainage, sewer, and stormwater planning.
Foundation Design Recommendations: Providing site-specific guidance on shallow and deep foundation types, pile design, and subgrade preparation.
Geotechnical engineering is at the core of every successful construction project. At NCEL, we provide comprehensive geotechnical investigations and consultancy services that are essential for understanding the physical and mechanical properties of soil and rock beneath construction sites.
Soil Investigations: Drilling, sampling, and testing to determine soil composition, density, moisture content, Atterberg limits, and shear strength.
Bearing Capacity Analysis: Assessing the load-bearing capacity of soils to design safe foundations for buildings, bridges, and roads.
Slope Stability Analysis: Evaluating embankments, natural slopes, and cuttings to prevent landslides and structural failures.
Our advanced testing methods, supported by state-of-the-art equipment, provide clients with detailed insight into the mechanical properties of soils and construction materials. From strength and compaction characteristics to moisture-density relationships, we deliver precise data essential for informed geotechnical and structural design decisions. At NCEL, all testing is conducted in line with SABS (SANS), ASTM, AASHTO and other international standards to ensure reliability and compliance.
Concrete Testing, In Situ Testing (core drilling and rebound hammer test): Slump tests, cube compressive strength testing (7, 14, 28 days), workability, durability, and mix design verification.
Asphalt & Bitumen Testing: Marshall Stability, bitumen content, temperature susceptibility, and mix design to ensure pavement performance.
Aggregate Testing & Relative Density,: Grading analysis, crushing value, impact value, flakiness, angularity, and moisture content – essential for concrete and road layers.
Soil Testing, Hydrometer Analysis: Compaction (Proctor), CBR (California Bearing Ratio), Atterberg limits, permeability, and triaxial tests to evaluate suitability for foundations and roads.
Cement & Mortar Testing: Fineness, setting time, soundness, and compressive strength to ensure binding quality in masonry and concrete.
Bricks & Blocks: Dimension, compressive strength, water absorption, and density tests to confirm conformity with construction codes.
Steel Reinforcement Testing: Tensile strength, elongation, and bending properties of rebar and structural steel.
Field testing: This includes density testing, Ball penetration testing, DCP tessting, Moisture content, deflection tests
Geotechnical testing: Potential collapsible test, Consolidation (Oedometer), Triaxial testing, Volumetric test, Chemical analysis
