H-4140-GeoGauge™-Stiffness/Modulus Gauge

Non-nuclear Soil Density Gauge

Protea is the supplier of the Humboldt H-4140 non-nuclear GeoGauge / Stiffness Gauge in South Africa , Botswana and Mozambique. We recently supplied the Cape Town University of Technology with a H-4140 GeoGauge.

H-4140 GeoGauge™ / Stiffness Gauge

The GeoGauge is used to control the compaction process by the using the design engineering properties of stiffness and modulus to gain a more accurate view of the state of compaction. Stiffness and modulus can reveal weak and/or problem areas in construction that density readings can not determine. The GeoGauge can help you to control the quality of your construction better by improving uniform layer properties for good stress transmission and distribution from surface to sub grade. This results in better quality construction, which leads to longer pavement life, longer lasting surface smoothness, reduced maintenance and less chance of pavement failures.
