Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete. Though it is a cost-effective technique with a shorter completion time, [ 1 ] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.

[citation needed] The filling can be performed from the surface of the slab or from the side of the slab if available. Separating the fill process from the lifting process is crucial in this system. After the void is filled with sand, the lift occurs. The concrete is lifted about ½ - ¾ inches and the filling process resumes.
A company faces nearly $60,000 in fines after two workers were crushed by a concrete slab at New York’s JFK Airport earlier this year, federal officials say.
Spancrete produces precast, prestressed concrete products that are used in commercial, industrial, institutional, residential and multifamily construction projects in the Midwest and Southeast. The company also manufactures and sells hollowcore extrusion machines that are used to produce precast concrete internationally.
The scope of the project called for extensive concrete work that consisted of slabs in excess of 2,000,000 square feet and used more than 65,000 cubic yards of concrete to complete. In order to meet the demands of the ambitious timeline for completion of the foundation, Conco worked in four separate areas simultaneously.
