As well as material investigation which includes center line, borrow-pit, geotechnical and foundation investigations, with test results delivered in a fully comprehensive professional report.

Soil and Gravel Testing

DUMAKO LAB’s Soils Laboratory offers clients numerous basic and advanced soil and gravel tests. Soil or gravel testing assists with the evaluation of soil properties to engineering requirements in terms of bearing capacity, material durability and robustness.

Every sample submitted for testing goes through a unique registration process captured in our computer database system before it is processed through our
different divisions.

All samples are prepared before tests are conducted and dependent on the type of test required, the sample will migrate through a variety of processes.
The following basic testing is available from our laboratory:
• CBR (California Bearing Ratio)
• UCS (Unconfined Compressive Strengths)
• MDD and OMC (Maximum Dry Density and Optimum Moisture Content)
• Road indicators (Sieve analysis and Atterberg limits)
• Nuclear density tests
• Geotechnical tests
• Permeability
• Collapse potential
• Foundation investigations TO NHBRC (National Home Builders Registration
Council) standards
• DCP Testing (Dynamic Cane Penetrometer)
• Compaction testing on site (nuclear method or sand replacement)

Asphalt and Bitumen Testing

DUMAKO LAB is positioned to carry out some of the most specialized asphalt testing in South Africa, adding value not only through the contribution of our
resources, but through innovation and accredited best practice methodology. We offer the full scope of design and acceptance testing on hot mix asphalt
either in our laboratory or on-site namely:
• HMA Design (Hot Mix Asphalt)
• Gyratory compaction
• Modified Lottman
• Mobile load simulator (MMLS3) evaluation

Customers receive the most accurate evaluation of properties such as strength, durability, reliability, longevity, rutting and fatigue. We assist with testing of newly researched or asphalt base designs in which we facilitate on mix design and slurry seals to serve customers’ ever changing needs. A fully compliant binder testing laboratory is incorporated into our asphalt testing laboratory for design evaluations, control testing and acceptance testing such as the Brookfield Viscosity Test on polymer modified binders. Our quality assurance and control testing procedures incorporate:
• Marshall Control
• indirect tensile strength
• Immersion index
• Maximum theoretical relative density
• Bulk relative density
• Binder content
• Moisture in asphalt
• Bitumen testing

Concrete Testing

During the construction process various quality standards need to be met to ensure all materials used in the building process meet the high standards of the
building industry. Our modern, state-of-the-art concrete laboratory and highly trained, experienced staff are able to provide the following services to this
specialized field:
• Greenfield investigations
• Forensic testing including site damage ‘and failure investigates
• Quarry assessments
• Batch plant efficiency
• Routine site testing
• Aggregate analysis
• Optimized concrete mix designs
• Site sampling
• Fire and storm damage assessments
• On-site pull out tests
• Deflection measurements on slabs and beams under static and dynamic loads
• Core drilling and core testing
• Elastic modulus
• Shrinkage and creep determination
• Concrete durability testing which include oxygen permeability
• Water sorptivity
• Chloride conductivity
• Flexural strength testing on concrete beams

Strength testing on concrete masonry units such as bricks, blocks and paving units is also conducted. Additional testing on masonry units would include
absorption, efflorescence (dimensions), shrinkage and expansion.
