Polyurethane Concrete Raising Vs Mudjacking

Polyurethane Concrete Raising Vs Mudjacking

There’s nothing more sad than some sunken concrete…

Mudjacking is a method of raising and supporting sunken or unstable concrete slabs by drilling holes and pumping material under them.

Polyurethane Vs Mudjacking

How it works

The concrete slab is used as a delivery point for poly foams that raise concrete, fill voids, and stabilizing soils. The hole is drilled through the slab. A delivery port is installed. The port has an injection gun on it. The material is delivered through the port and slab. Within seconds, the material expands, raising the soil and raising the concrete.

A precise, easy process

Incremental injections are used to raise concrete. Lifting foam will expand within a few seconds and allow you to monitor the raising and prevent over raising the slab. The foam should be delivered using an air-purged gun. The equipment will keep the injection port open so the foam can expand before it is injected.

The injection foam gun is a simple design.

The concrete lifting injection equipment was designed for concrete lifting. Half as many replacement parts as the Fusion Gun.

  • Valve Operated with one-way check valves.
  • Monitor your pumping pressures as you work.
  • Plugging ports are identified before you pump.
  • Rolling handle makes it easy to turn on air or material flow.

Spending more time pumping and less time fixing and cleaning your equipment will save you time and money.

Polyurethane Foam Can Also Be Used for:

Concrete settling isn’t the only issue foams can solve. There are voids under slabs in areas where there have been wash outs. The material will weigh 15 to 25 times less than a traditional mudjacking or cementitious grout mix, applying less stress on an already failed sub grade.

Concrete raising and void filling are the same process. The heat is created when the dual component foams are installed. A layer method is needed to allow heat to evaporate safely. The Stewardship manual will be given to all dual component customers. There are safety precautions to be observed when injecting dual component foams.

Joint/Slab stabilization is required when slabs lack support. When loads are applied, the slabs can crack.

The voids need to be filled to eliminate movement. Due to its long reaction time and minimal expansion strength, this type of foam is ideal for joint bowing walls/slab stabilization applications. It will take longer to expand, which will allow for better coverage under the slab.

Water gets through cracks and gaps in the wall when the soil washes away. The wall joints can fail if cracks and voids form. A solid foundation is at risk of being damaged. It is possible to repair a seawall with HydroFOAM at a fraction of the cost of a wall replacement. Repairing seawalls with HydroFOAM will not add weight to the soft soil and will last longer.

A quicker, more cost-effective choice

When compared to concrete replacement, the process of raising concrete with a foam is cheaper. Replacing concrete is much faster than it is with it. Within minutes, repair areas are ready to use. The ease of material process and clean-up is a distinct advantage over mudjacking.
