General Floor lifting Benefil
Lifting subsided concrete floors
- As a result of the soil composition in numerous regions of various countries many companies and private owners are confronted with subsidence of concrete floors. We have developed a technique where Benefil® hardfoam lifts the subsided floor back to its original level. Procedure: Before work starts, our experts examine the floor and a quotation is made based on their findings.
After written agreement the commission will be executed as follows:
- Holes of 45 mm are drilled in the subsided floor
Plugs are placed in these holes
The foam is pumped at a low pressure through these plugs from the truck
The floor is controlled during the lifting by means of laser equipment
If you calculate that 1 bar is equal to 1 kg/cm2 work pressure and you then calculate that 1 m2 is 10,000 cm2 - it may be said that a work pressure of 1 bar equals 10 ton/m3.
This explains the simplicity of our technique.
Advantages
- The cost price of lifting is between 30-50% of the price of a new floor
There is relatively little disturbance of company activities during the lifting process
No disturbance in the area relating to dust or shaking etc.
The foam is environmentally friendly and recyclable
A minimal weight is applied during the lifting
Showroom
- Injected under sunken concrete floors or driveways, Benefil® firstly fills any voids and then, with even pressure, raises the concrete back to its correct position.
