Materials Testing
What is construction materials testing?
Construction materials testing checks that materials such as concrete, mortar and asphalt meet the strength and quality required by the project specifications. Test results give owners, contractors and engineers documented proof of quality.
Which tests does your laboratory perform?
Our laboratory in Mandaue City performs concrete cylinder compression tests (6 × 12 in), mortar cube tests (2 × 2 in), asphalt tests including Marshall stability and flow, and rebound hammer tests on in-place concrete. Contact us if you need a test that is not listed.
How are concrete samples collected?
Concrete cylinders are cast on site from the pour, cured, and delivered to our laboratory, where they are tested at the ages required by the specification (commonly 7 and 28 days).
How do I receive the results?
We issue a written test report for each set of samples, identifying the project, sample, test method and result.
Field Density Test
What is a field density test?
A field density test measures how well soil or aggregate fill has been compacted on site, by finding its in-place density and moisture content and comparing them with the required compaction.
Which method do you use?
We use the sand cone method. A small hole is dug in the compacted layer, the removed material is weighed, and the volume of the hole is measured with calibrated sand.
When should field density tests be done?
After each compacted layer is placed and before the next one goes on, so that any layer that does not pass can be reworked in time.
Where do you perform field density tests?
On project sites across Cebu, including Lapu-Lapu City, Cordova and Mandaue City.
Soil Boring Test
What is a soil boring test?
A soil boring test drills into the ground at the proposed building location to find out what soil layers lie beneath the site, and how strong they are, before the foundation is designed.
What does the investigation include?
Drilling of boreholes with our own soil boring rig, soil sampling at set depths, Standard Penetration Tests (SPT), and borehole logs and a geotechnical investigation report for the structural engineer.
Which projects need a soil investigation?
Any new building or structure whose foundation must be designed for the actual ground conditions, from residences and commercial buildings to warehouses, cold storage facilities and hangars.
How do I arrange a soil boring?
Send us the site location, the proposed building and the number of boreholes required by your engineer, and we will prepare a proposal.
