Since 2011, we have been providing our services to residential, commercial, and industrial clients alike.
The process of concrete polyjacking is rather simple, consisting of three main steps:
Step 1
First, a pattern of holes is drilled through the sunken slab of concrete.
Step 2
A hydraulic pressure pump is used to inject polyurethane foam under the slab, raising it to the desired height. The amount of rise is carefully controlled using the A-Triple-M Contracting pumping unit.
Step 3
After the concrete has been raised to the desired level, the injection holes are patched using a fast-setting sand/cement mixture or other patching material.
Materials Used:
Levelling Foam: The levelling foam is a formulation of high-density polyurethane. This high-density, closed-cell polyurethane has the following characteristics and properties:
- Density, Lb/Cu Ft Compressive Strength
- (ASTM D1622) (ASTM D1621)
- 3.0 (48 kg/m3) 40 psi (275 kPa)
- 3.5 (56 kg/m3) 50 psi (344 kPa)
- 4.0 (64 kg/m3) 60 psi (413 kPa)
- 6.0 (96 kg/m3) 110 psi (758 kPa)
Polyurethane Foam: Polyurethane foam has a minimum compressive strength of 40 psi (275 kPa). Its formulation will reach 90% of full compressive strength within 15 minutes from injection.
