Welcome to SoilStructure Software

We are selling you efficiency in your design + enhancing your profit margins. With increasing urban development and constant exposure to difficult soils, a consultant’s time is best spent on comparing alternate designs.  With SoilStructure software, you can produce the results and charts at a quick speed and ease.  Leave the hand calcs/spreadsheets behind and concentrate on developing buildable & practical designs. SoilStructure software is priced for the one person consulting firm but is technically rigorous for the large firm.

We invite you to download free any of our DEMO and take it for a spin.

Client Benefit (Robust Design): An existing substructural designer used LATERAL FOUNDATION to proportion a retaining wall founded on drilled piers & grade beams.  ”There was a landslide on the adjacent lot, but the retaining wall founded on piers that was proportioned with LATERAL FOUNDATION v1.0 is still standing”.

Client Benefit (Higher Billing Rate): A small engineering firm used CANTILEVER RETAINING WALL to proportion 4 retaining walls in 1.5 hrs.  ”I was able to bill $1,000 for work done in 90 minutes using CANTILEVER RETAINING WALL v2.0″

Client Benefit (Approved Report): A mid size consulting firm used LIQUEFACTION SPT to analyze a liquefiable site.  ”We were able to be comfortable with our analysis in one day use & got City approval with our first submittal”

Client Benefit (Quick Solution): A shoring subcontractor uses SBWall & TBWall programs constantly. “Even though I have more expensive retention software, I always use SBWall & TBWall first.  I get what I want & it is very user friendly to use”

Client Benefit (Subconsulting): A leading geotechnical engineer had to help a colleague prepare settlement estimates.  He used SETTLEMENT ANALYSIS to estimate primary consolidation in a timely manner.

Client Benefit (All or nothing): A structural engineer who specialized on custom estate homes was tired of loosing projects because other firms were able to do temporary shoring design in house in addition to building structural design.  ”I purchased SBWall which is very easy to use & no longer worry about shoring part of a job making me loose the entire project.  You have a very good software”.

Client Benefit (Modern Software): An engineering consultant has access to geotechnical software by other firms. “I like your charts and modern look of your software.  I need to purchase your Geotechnical Office Bundle”

Client Benefit (Affordable Software): Once we asked a repeat client why he purchased LATERAL FOUNDATION.  He said “It does the same thing as other software that cost twice as much.  Why should I pay more?”

Every client has their own benefit criteria.  You can benefit with the use of our software.
