Innovative Geotechnics is an engineering company with the aim of researching and developing geotechnical design and analysis programs.
Innovative Geotechnics provides innovative geotechnical design tools for soil-structure interaction and deep foundation problems such as single piles or pile groups under lateral and vertical loads.
Single Piles and Pile Groups
Innovative Geotechnics provide geotechnical design tools for soil-structure interaction problems such as pile groups, laterally loaded piles, nonlinear p-y curve generation and rock socket design, including single piles or pile groups under lateral and vertical loading based on finite element method. Our programs are focused on the geotechnical analytical knowledge, improving user engagement and reducing potential input uncertainties.
All geotechnical programs and software adopt simple input interfaces for the users to interactively enter the analysis information such as soil layer information, soil properties, and foundation design parameters.

ALLCPT Released
ALLCPT is a software developed and designed by Innovative Geotechnics for practical engineering interpretation of Cone Penetration Test Data in routine geotechnical design. Some of the important features and benefits are summarised as follows:
-
Various strength and stiffness correlations based on measured CPT data, such as effective cohesion, effective friction angle, undrained shear strength, Young’s Modulus, Shear Modulus, Constrained Modulus, Equivalent SPT blow counts, etc.
-
Graphical presentation of various results for single or multiple CPT records with extensive selection options for the plot formats.
-
Cyclic liquefaction analysis tool which can be used to assess the liquefaction potential due to cyclic loading based on measured CPT data.
-
Flow liquefaction analysis tool which can be used to assess the flow liquefaction due to strain softening with a resulting loss of shear strength.
-
Pile capacity analysis tool for both driven piles and bored piles based on LCPC method as proposed by Bustamante and Gianeselli (1982). Users can consider (1) Eurocode 7; (2) ASSHTO Code and (3) AUS Piling Code for pile capacity design. The load-settlement curve is also estimated based on Fleming’s approach (1992) for axially loaded single piles.
-
Wick drain analysis tool to evaluate consolidation times for embankments on soft soils with the presence of wick drains based on single or double drainage conditions.
-
The imported CPT file can be exported into a file format which is compatible with Plaxis CPT input for soil layer creation.

PileAXL 2.3 Released with Significant Improvements
PileAXL 2.3 is formally released with the following updates:
-
Fully support a wide range of design standards such as Allowable stress design, ASSHTO, Eurocode 7 - UK National Annex, Eurocode 7 - Singapore National Annex, Eurocode 7 - General and Australian Piling Standard AS 2159-2009;
-
The position of the pile head can be specified below the ground surface, which allows the users to consider the situations where the top of the pile could be further below the surface;
-
Two different analysis options are available for load-settlement assessment of piles under axial load: (1) Load transfer method with using automatically generated t-z and q-w curves and (2) Fleming's method;
-
The empirical approach based on SPT-N values for estimating ultimate shaft resistance and ultimate end-bearing resistance based on the recommendations in CIRIA Report 143 (1995).

PileAXL 2.2 is released with the following improvements:
-
