Compaction Control

Services include both on site and laboratory analysis

Our nuclear density and compaction test reports are NATA endorsed.

At Geotechnical Services, we provide comprehensive compaction and earthworks testing services that cover both on-site and laboratory analysis. These services are crucial for any construction project as they ensure that the materials and methods being used meet the required specifications and standards of the site, which in turn provides a strong working platform that decreases the likelihood of premature failure of construction and costly maintenance or repairs.

We understand the importance of reliable and timely testing of construction materials for all projects.

Our services as a Geotechnical Inspection and Testing Authority (GITA) include onsite inspection and testing by experienced technicians for the duration of the earthworks in accordance with AS 3798 – Guidelines on earthworks for commercial and residential developments.

Level one testing, as defined in AS 3798, provides for full-time inspection for the placement of controlled fill and compaction testing in accordance with AS 1289 – Methods of testing soils for engineering purposes. We use a portable soil moisture density gauge (SMDG) to perform field density testing during the placement of controlled fill (earthworks). Feedback and technical assistance are provided to your nominated earthworks contractor throughout the project to ensure the testing is performed accurately and efficiently.

In addition to our field density testing, we also offer laboratory analysis of soil and aggregate material. We use state-of-the-art equipment and techniques to guarantee accurate results that meet the standards set by relevant regulatory bodies.

As part of our commitment to providing comprehensive and reliable services, we provide a detailed report outlining the work completed, a summary of test results, site maps, daily site inspection records, and level one certification. Our nuclear density and compaction test reports are NATA endorsed, ensuring that they meet the highest standards of quality and accuracy.

Our compaction control services include;

  • Level one supervision/certification (GITA services)
  • Nuclear field density testing

Compaction control in geotechnical engineering

Compaction control is an essential aspect of geotechnical engineering that involves ensuring that soil, rock, and other materials used in construction are compacted to the appropriate level. The process of compaction involves using mechanical equipment, such as rollers or vibratory plates, to compress and consolidate the soil or rock to achieve maximum density and stability.

Compaction control typically involves several steps, including selecting the appropriate compaction equipment and testing methods, determining the optimal moisture content of the material being compacted, and monitoring the compaction process to ensure that the desired level of density is achieved.

In geotechnical engineering, the primary goal of compaction control is to ensure that the soil or rock being used in construction is stable, durable, and capable of supporting the intended loads and stresses. This is particularly important in applications such as road and building construction, where the performance of the structure relies heavily on the quality of the underlying soil or rock.

Soil Testing

Soil compaction test for construction

Compaction is a crucial process that involves the removal of air voids from soil, thereby reducing the surface area around each particle and increasing the soil density. This transformation in the soil structure leads to a greater unit weight than non-compacted soil, which is essential in creating a sturdy foundation for construction. The construction of various structures, such as buildings, roads, and pavements, typically requires compaction to ensure their durability and stability over time.

Compaction testing is a procedure that verifies whether the soil has been compacted to the necessary density to provide adequate support for a proposed construction project. Its purpose is to ensure that the ground has been compacted sufficiently to meet the required specifications.

Types of compaction test of soil

Standard compaction test

This test measures the maximum dry density and optimum moisture content of a soil sample using a standard compaction apparatus.

Sand replacement test

This test involves excavating a hole in the ground and replacing the soil with a known quantity of sand. The volume of sand required to fill the hole is then used to calculate the in-situ density of the soil.

Nuclear density test

This test uses a nuclear density gauge to measure the density of the soil in-situ.

Plate load test

This test involves loading a circular plate onto the soil surface and measuring the resulting settlement. This is used to calculate the soil’s modulus of elasticity and bearing capacity.

Dynamic cone penetrometer test

This test involves dropping a cone into the soil and measuring the penetration depth. This is used to estimate the soil’s in-situ density and strength.

What is the compaction test Australian standard?

AS1289.0 is the methods of testing soils for engineering purposes, this includes a range of methods for the various types of compaction tests.
