PREVENTIVE GROUND CONSOLIDATION

Very often, an insufficient load bearing capacity of the ground hinders the carrying out of applications which would modify the tensional equilibrium of the structure. In any case, with an examination of the foundation ground together with a check on the load variations to which the ground will be subjected, it is possible to establish if applications will provide suitable preventive operations on the ground or on the foundations.

For example, the addition of an extra floor to an existing building can bring about an increase in the forces transmitted to the foundation ground, such as to exceed its load bearing limits and then cause a subsidence in the near or not too distant future.

In cases like this, the URETEK Deep Injections® method can be used preventively. One must determine the load variations to which the ground will be subjected and hence the load bearing level which must be reached.

The increase in load bearing capacity of the ground, obtainable with the patented URETEK Deep Injections®, is immediate and verifiable by penetrometric or pressure tests, immediately after the application. It allows the foreseen work to proceed rapidly and with the certainty that it will not compromise the stability of the building.

The URETEK Deep Injections® can also be used on ground yet to be built upon: a typical case is the plinths of industrial buildings which, in concentrating very high loadings, require a foundation ground with extremely high load bearing capacity. If the foundation ground does not have sufficient resistance, the URETEK Deep Injections® offers the simplest and safest solution.

Among the advantages of the URETEK Deep Injections®, we underline the possibility of localized applications, which can concern weak and deep strata of earth exclusively. For example, if a weak stratum of earth is discovered at a depth of 3.5 metres (11 ft), with a thickness of 50 cm (1,6 ft), it would be possible to act on this only, in carrying out a preventive consolidation.

Preventive consolidation of a building during its restructuring.

Another useful application of the URETEK Deep Injections® concerns the consolidation of the faces of an excavation. Suppose that we want to construct a building in the immediate vicinity of another construction.

The excavation for placing the foundations may endanger the stability of the existing building. The URETEK Deep Injections® provides a solution to this problem by operating preventively on the existing building in consolidating its foundation ground before the excavation is begun.

The URETEK Deep Injections® can also be used to consolidate the faces of an excavation in incoherent ground so as to avoid their falling in.
