Strength & Safety With Expert Concrete Testing At K & H Geotechnical Services

At K & H Geotechnical Services Pty Ltd, we test concrete to the highest standards. We know how effective using robust and reliable concrete is in all your construction works. That is why we have a team of experienced experts to ensure that your concreting structures are of the best quality and ensure safe use.

Why is Concrete Testing Important?

Concrete is a primary material in most construction projects. However, how does one ascertain that the concrete is strong enough? How can you be sure it will last? These are the questions that the testing of concrete answers.

Testing concrete helps ensure that the structures are safe and durable. The concrete tests determine the properties and behavior of concrete so it meets the essential specifications and standards of the project.

Precision in Soil Analysis

Trust K&H Geotechnical Services for accurate soil assessments, ensuring your project’s foundation is built on solid ground. Our dedication to excellence guarantees reliable results every time.

Our Concrete Testing Services:

Soil Testing

Compressive Strength Test:

The test determines the ability of concrete to bear load without breaking. It provides a general idea of whether or not a mix is strong enough for a project.

Soil Testing

Slump Testing:

Want to know if your concrete mix is of the right consistency? Our slump test verifies the workability of the concrete, ensuring that it can be effectively placed and compacted.

Soil Testing

Air Content Testing:

The right air content in concrete is crucial for durability. We test the air content of your concrete to ensure that it can withstand weathering and freeze-thaw cycles.

Density and Unit Weight Tests:

These tests ensure that your concrete mix is proportioned correctly regarding the ingredients, which is critical to its strength and stability.

Soil Testing

Flexural Strength:

The test is essential to determine the ability of concrete to resist forces tending to bend. The importance of this in pavements and other structures put under flexural stress is quite recognized.

Soil Testing

Temperature Monitoring:

Temperature monitoring makes it possible to ensure that the concrete acquires the designated characteristics and strength of concrete over time.

Soil Testing

Test on Chloride Ion Penetration:

This test measures the resistance of the concrete to penetration of chloride ions, which is essential if the structure is to be subjected to de-icing salts or a marine environment.

Shrinkage Testing:

This test measures the amount of shrinkage that concrete undergoes because of drying and hardening, providing some aid in predicting and preventing cracking problems.

Water Permeability Test:

It is important to ensure that concrete resists the penetration of water for most structures exposed to water.

Admixture Evaluation:

Determine the effectiveness of different admixtures in changing concrete properties to ensure that concrete achieves the desired properties for a given application.

Aggregate Testing:

It includes the analysis of the quality of aggregates incorporated in the concrete mix, ensuring that they meet the required standards.

Concrete Coring and Sampling:

Taking cores and samples from existing structures to assess their conditions and check for conformance to specifications.

Frequently Asked Questions

How often is concrete to be tested?

Concrete needs to be tested at various project stages—when it is fresh and at every available point after it has hardened. The exact frequency may depend on project needs and regulations.

Is it possible to perform concrete testing on the spot?

Yes, so many tests can be done on-site, such as the slump and rebound hammer tests. A few tests, like the compression test, need samples to be taken to the lab.

What factors affect concrete test results?

Many factors can influence test results; e.g., mixture proportions, curing conditions, method of sampling, and conditions during testing.

What is non-destructive testing (NDT)?

NDT is a test that does not cause damage and effectively checks the quality of concrete; examples are tests using rebound hammers and ultrasonic pulse velocity.

How long does it take for test results to come back?

This differs. Some will provide results on-site, while others—for instance, the compression test—will take several days to weeks.

Can the tests predict my concrete structure's life?

On the other hand, testing can give information about the present quality and durability of the concrete. However, the prediction of its life can also depend on environmental conditions and maintenance.
