THE PROBLEM

Settlement in foundations and ground slabs were observed and reported to Uretek.

THE SOLUTION

Affected area (slab and foundations) stabilized and uplifted successfully to its preoccupancy level The sensitive chemical tank needed to be stabilized without closing down the plant.

Customer needs

Settlement in foundations and ground slabs were observed and reported to Uretek. after a site visit Uretek technicians found that the settlement took place due to the differentiation of soil types (Pockets) at a depth of (3 : 7.5 m) and water seepages from production plant caused washing off the fine material from the bottom of the isolated footings as well as the ground slabs which resulted in cavitation.
The ground slab of affected area needed to have soil stabilization at a depth of ( 3 to 4 m) and slab lifting of sunken areas.
Moreover, the selected isolated footings required soil stabilization at (deeper levels -6.00 m to -7.50 m) in order to carry the imposed load of structure.

THE SOLUTION

Soil stabilization and Relevelling
This application applied to the whole slab area in intervals of 1.5 meters with 190 points to stabilize the soil at -3.00 from slab on grade. After that Uretek technicians used the same tubes (used for stabilization) to uplift the sunken areas (slab on grade) to restore its floor to the targeted levels. Deep injection treatment for foundations (Stabilization & Uplifting) applied down to a depth of (-3: -6 m) beneath the isolated footings carrying the steel structure.
