THE EFFECTIVENESS of Uretek's deep injection method for underpinning has been boosted with the launch of Geoplus, its 'super consolidating' geopolymer.
The firm claimed the material can create an expansive thrust of 10,000kPa, up to 20 times greater than existing polymers.
Stability and speed of the chemical reaction between the two liquid polymer components that combine to strengthen soil beneath foundations has also been improved.
'This enables more precise prediction of mechanical and consolidation characteristics than was previously possible, ' Uretek said.
Geoplus has an elasticity modulus compatible with a wide range of soils, 'excellent' resistance to tensile and flexural stress and has neutral environmental impact, Uretek added.
The geopolymer has undergone extensive laboratory and field testing in Italy and is certified by the University of Padua's geotechnical department.
