Polyjacking Vs Mudjacking

Difference Between Polyjacking And Mudjacking

Polyjacking Vs Mudjacking, Mudjacking has been the industry's go-to approach for lifting and leveling sunken concrete for decades. But a newcomer has joined the scene and, whilst the procedure is similar, the fabric used is a long way superior. Let's take a seem to be at the variations between mudjacking and polyjacking and discover why polyjacking is the satisfactory preference for any concrete lifting project.

But what about polyjacking? Well, the lifting technique is similar, however the use of polyurethane foam offers it an edge. Polyurethane foam is denser, greater long lasting and can be injected thru a smaller, much less obvious gap than mud slurry. We use polyurethane for all our concrete lifting projects.

What Is Mudjacking?

Mudjacking is additionally acknowledged as concrete leveling, strain grouting, and slab grouting. Sand, cement, and different substances mix to make a combination regarded as a slurry. This combination is then pumped into holes drilled into the concrete to increase and degree it. Mudjacking is first-class for concrete that’s in exact circumstance however is no longer level. It works for slabs, driveways, porches, walkways, decks, steps, and more.

There are some tasks the place mudjacking isn’t the fantastic choice. It won’t work for slabs that are heavy or load-bearing due to the fact it doesn’t have sufficient electricity to pass them barring inflicting damage. It can additionally reason greater troubles for severely broken concrete due to the fact it can’t fill each gap and might also lead to sinking over time.

What Is Polyjacking?

Polyjacking is a more moderen approach for lifting and leveling concrete. Polyjacking entails injecting engineered polyurethane foam underneath the concrete to carry and level. The polyurethane we follow is high-quality. Designed to face up to weight and water, the two-part polyurethane combine will now not deteriorate in the soil.

Depending on the measurement of the job, polyjacking can be accomplished inside a day. Commercial and larger-scale tasks will take greater time due to the fact there is a lot greater planning and floor region to cover. However, the majority of residential initiatives are completed inside this timeframe. With polyurethane, the curing technique is shorter. Consequently, you’ll be capable to stroll on or use the repaired region nearly immediately.

Mudjacking Pros

This task process is normally less expensive
The mud slurry is made nearly completely from herbal materials, making it an environmentally pleasant alternative
Many contractors are acquainted with the technique

Mudjacking Cons

Mud slurry is extraordinarily heavy (roughly 50x heavier than polyurethane) and can reason similarly soil compression over time
The slurry is tough in texture and has some challenge absolutely filling the void beneath a concrete slab
Mudjacking is a low cost brief time period solution, however will want to be repeated each and every few years to hold leveling
Slurry substances are susceptible to washing out if penetrated with the aid of water due to heavy rainfall or negative drainage
2" holes have to be drilled into the slab for pump get admission to

Benefits of Polyjacking in Construction

The predominant advantages of polyjacking in building are:

Polyjacking prevents the alternative of concrete surfaces, which is a pricey process. Hence, polyjacking is cost-effective.
The curing procedure is quicker and the floor can be used inside a few hours.
The system keeps the compressive energy and structural integrity of the concrete surface.
It seals joints and cracks and prevents future heaves.
Polyurethane is an environmentally friendly cloth composed of 39 to 49% renewable and recycled materials.
There is no concrete or grout splatter at some stage in the process, developing a easy working environment.

Application of Polyjacking in Construction

Polyjacking can be used for the following applications:
Sidewalks
Driveways
Walkways
Garage and basement floors
Repair of office floors, sports activities arenas, warehouses, etc.

Features of Polyjacking

Polyjacking is additionally referred to as polyurethane concrete lifting or polylift. In the process, holes are drilled over the settled concrete slab and high-density polyurethane foam is injected into the holes to fill the voids and cracks.
Once injected, the polyurethane foam expands to 7 ft below every drilled hole. This growth helps the elevating of the concrete slab whilst stabilizing the structure.
The foam used for the polyjacking manner does no longer ruin down over time, in contrast to the mud or slurry used in the mudjacking process.
The holes drilled for the polyjacking system are smaller (⅝’’) in contrast to different concrete restore methods.
The polyurethane foam fabric used for the manner is light-weight in contrast to the mudjacking slurry. Hence, they do no longer exert strain on the underlying soil.
The method includes drilling fewer holes to inject the foam material.

Mudjacking Cost

Mudjacking expenses $3 to $6 per rectangular foot, and foam jacking is $5 to $25 per rectangular foot. The common price of slabjacking to increase a concrete slab is between $500 and $1,800, with most spending $830. Concrete leveling expenses rely on the measurement and circumstance of the slab and soil conditions. Mudjacking is first-rate for concrete slabs, driveways, patios, porches, walkways, pool decks, and steps. Foam leveling is great for load-bearing concrete that requires extra support, such as foundations, basements, and storage floors.
