Static load testing products

Foundation load testing products offer an easy to use and cost-effective solution, that help to improve overall operational safety.

ASLT automatic static load test system

The Auto Static Load Test (ASLT) system is purpose designed to control and monitor static load tests automatically.

The ASLT system is supplied with a rugged site notebook, pre-loaded with the ASLT controlling software and calibration for the transducers.

The system incorporates a data acquisition battery back-up, which allows testing to continue in the event of a power failure, without the loss of any intelligence. 

Improved safety features enable you to monitor tests from a safe distance of up to 25 meters, removing the need for operatives to be in close proximity to potentially dangerous, highly loaded system components.

Data acquisition, pump control and data storage is all controlled by the user friendly ASLT software, and operated within Windows operating systems.

The software enables the operator to set up and save loading templates, as well as review and alter alarm settings accordingly. As the test proceeds the user can view all of the data in real-time and view plots of load versus settlement.

Displacement gauges can be calibrated in-situ with supplied gauge block and re-set remotely. Should the test be halted for any reason e.g. power failure, there are routines which enable the test to recommence without any loss of data.

The load, deflection and load maintainer readings are collected by the ASLT data logger and downloaded to a rugged on site PC. All data is presented in accordance with Eurocode7-EN-1997, the European standard for design of geotechnical structures.

Our user friendly system allows data to be viewed in real-time, comparing plots of load versus settlement as testing progresses. The software enables users to set up and save loading templates, and to also review and alter alarm settings accordingly.


 SLT2 static load test system

The SLT2 is a purpose designed system for monitoring static pile test and improving operation safety.

SLT2 is a highly accurate and robust system that enables you to monitor static pile tests whilst also ensuring the safety of site operatives.

Featuring a 25m cable, users are able to monitor safely and accurately from distance, eliminating the need for personnel to enter potentially dangerous testing zones.

The user friendly software allows operators to view data in real-time whilst plotting the load settlement data as the test progresses. Should the test be stopped for any reason, there are back up routines which enable testing to recommence without any loss of data.

The SLT2 logging software is designed to operate on a PC with Windows operating software, and the data acquisition unit is connected to the PC running this software during the test.

There are two viewports to the software:

Data viewport - This enables you to enter the site details, calibrate and zero transducers, view load and settlement in real-time and also plot the load test in progress. Displayed transducer readings are refreshed every second.

Table viewport - This enables you to view a table of values saved during the tests at one minute intervals. This includes time, elapsed time, load (KN), individual gauge displacements (mm), average settlement (mm) and rate of settlement (mm/hr).

Printing

Once a test is stopped it is possible to print the following results:

  • Table of results showing time, elapsed time, displacement readings, load readings and settlement rate
  • Graph of applied load versus settlement at the pile head
  • Graph of applied load and settlement at pile head versus elapsed time

All data is sorted in ASCII format making it possible to export and use in other applications.
