Concrete Leveling
The technique of concrete leveling has been around for years, with varying different methods to achieve the repair of the concrete being used by contractors throughout the years.
In this day and age the best way to level cement is by the use of mudjacking, or slabjacking as it is also known.
Accounts of leveling concrete date back to the 1900's, through the use of hydraulic pressure with early contractors using a mixture of materials that were to hand, more often then not soils that were available close to the area in need of repair, these soils sometimes included crushed limestone and cement for added strength.
This mixture of soil, limestone and cement produced a 'mud' like substance which the contractors then used to level off the sunken concrete, hence the term mudjacking was born.
Although more traditional mudjacking technniques are still used to level concrete, modern contractors these days more often then not use an expanding polyurethane foam or grout, to achieve the same results of concrete leveling, this expanding foam has many benefits over the traditional mixture used in mudjacking.
It is not actually the pressure of the expanding foam being injected that causes the concrete to level and lift, it is actually the expansion of air bubbles in the injected material below the concrete slabs surface that performs the actual lifting action as the liquid resin fills the void, reacts and becomes a solid structural foam, in some cases the use of this foam can repair the damaged concrete in a matter of minutes after being injected.
