Bi-Directional Static Load Test
BDSLT Redefined
Why Bi-Directional Static Load Test?
Bidirectional Static Load Testing (BDLT) is an advanced and efficient method for evaluating the load-bearing capacity of deep foundation piles and barrettes. This innovative testing technique is crucial for projects that require precise measurement of both skin friction and end bearing capacity in high-capacity foundations. The method involves performing full-scale static loading tests that evaluate the load performance of piles under axial compressive loads, which is essential for ensuring the stability and integrity of any foundation system.

Why Choose Us
Innovative Load Testing for Stronger Foundations
With over 70 years of experience and as pioneers in Bidirectional Load Testing, ARCOS Engenharia leads the industry in advanced foundation testing solutions.
We provide comprehensive, simultaneous measurements of skin friction and end bearing load capacity, delivering fast and reliable results with minimal disruption to your project.
Our method eliminates the need for heavy equipment and reduces risks, saving both time and money while ensuring worker safety.
Benefits of Bi-Directional Static Load Test
This method removes the need for additional anchor piles, simplifying the setup and reducing costs.
Traditional testing requires large weights or sandbags. With BDLT, we minimize the need for such resources, which means reduced effort and manpower.
We’ve extended the application of this testing method to small diameter piles, including mini piles and continuous flight auger piles, making it versatile for various project types.
