Soilworks products are the industry’s top standard due to our insistence on creating high performance soil stabilization and dust control products that stand up to rigorous testing – both in the lab and in the field. Our commitment to quality and performance has led to our involvement and testing in hundreds of real-world situations. The following library of reports, presentations, specifications, approvals and other similar documents provide you, our customer, the transparency and dependable assurance that is expected from Soilworks.

Comparison Between Results on Midwest and Soilworks Polymers

Test on polymers for soil stabilization for funding a project on anti-seismic design 

COMPARISON BETWEEN RESULTS ON MIDWEST AND SOILWORKS POLYMERS

Preliminary results on treated sands. We compared old tests obtained with Soiltac® by SOILWORKS with the tests on same type of granular material treated with SOIL SEMENT by Midwest (Formula A).  

 

Table of results:

 

 

SOILTAC 180 days

MIDWEST 30 days

UCS (KPa) after curing

7500

6800

UCS (KPa) after wetting

720

680

 

TEST are UCS Unconfined Compression Test on sand cylinders treated and left at the lab environmental humidity: for 30 days in case of SOIL SEMENT and 180 days for the SOILTAC.

The strength of SOILTAC after 30 days was lower circa 5 MPa (not reported). This means the Midwest seems to reach equilibrium in a shorter time.

Filtration of Soil Sement is easier because formula is less viscous and this seems an advantage for site treatment.

Remarks: we obtained same peak strength with two different commercial products. The values are sensibly higher than the minimum RISK obtainable with Geotechnical Intervention or maximum class according EC8 Euro code 8 Seismic Design. It means depending on buildings Midwest polymer can be used to change class of RISK from E the minimum to A the best one. Approximatively the worst humidity conditions guarantee a UCS with vapor coalescence of 700 KPa, means 3 times the CU of the norm. Liquefaction means a residual CU of 5 – 10 KPa class S1.
