|Chance is a world leader in designing and production of Screw Anchors and piles.
Foundations based on screw anchors can be built in a very short time in comparison with classic concrete foundations.
One must know soil profile in order to select appropriate anchors and design a foundations based on them. Chance engineers developed the "soil test probe", a mechanical tool which makes it possible to infer subsoil conditions from the surface of the earth. The soil test probe is screwed into the soil. As it displaces the soil, probe installation torque is measured in inch-pounds on a torque gauge, which is an integral part of the installing tool. Probe torque readings are then compared with the information on the Chance Soil Classification Data Chart and translated into the appropriate soil classification.
In civil engineering, even in housing industry, a reparation of cracking foundations, supporting the old and landmark buildings, etc make screw anchors irreplaceable tools.
