Dulles Geotechnical and Materials Testing Services, Inc. (DGMTS) proudly announces our expanded laboratory testing capabilities to provide Corrosion Test, which is used to predict the likelihood of corrosion or degradation of a material in the sample environment.

Our Corrosion Testing services include the following tests:

• Sulfate Ion Content in the Soil (AASHTO T290) and Water (AASHTO D516) – Tested by Spectrophotometer. Soils and water high in sulfates can produce sulfate attack in some types of concrete which deteriorates the mechanical properties of the concrete.
• Chloride Ion Content in Soil (AASHTO T291) and Water (ASTM D512) – Tested by pH/MV meter using Chloride Ion Selective Electrode. Chloride ions can enhance the corrosion of metals. Chloride ions are also a major cause for corrosion of steel reinforcement in concrete.
• pH of Soil (AASHTO T289 / ASTM D4972) and Water (ASTM D1293) – Tested by pH meter. An acidic soil or water can indicate a higher risk for corrosion of metals and concrete.
• Resistivity of Soil (AASHTO T288) and Water (ASTM-D1125) – Tested by Resistivity Meter. The value obtained from this method are relatable to the corrosion potential that a soil or water may exhibit.

Our Laboratory is accredited by American Association of State Highway and Transportation Officials (AASHTO), which in addition to corrosion test offers a wide range of testing services including direct shear testing, residual direct shear testing, consolidation testing, permeability testing, soil index testing, moisture/density testing as well as many other tests performed under the supervision of Professional Engineers and Laboratory Manager, who direct a staff of technicians with certifications by ACI, VDOT and WACEL.
