Why did Purlevel choose polyurethane concrete lifting over mudjacking? We did extensive research on the two methods to raise concrete and found polyurethane a far superior product. One of the most surprising reasons why customers prefer was the difference in hole sizes. Multipleholes are drilled and later patched but can be see after the filler is dry. Mudjacking requires a 2″ to 5″ holes as compared to the 3/8″ required with polyurethane.
Mudjacking Pros and Cons
- Less expensive. The cost of the concrete slurry used is less than the polyurethane.
- People are more familiar with the process since it has been around much longer.
- Mudjacking has a shorter lifespan since the material will eventually lose density
- The slurry mixture is much heavier and will add additional weight to the concrete being lifted and will further burden the soil underneath (100 lbs per cubic ft)
Polyurethane Pros and Cons
- More expensive due to higher material costs
- Lightweight (2 lbs per cubic ft) and will never lose density.
- Very clean process so no concrete splatter and wash down needed.
- Environmentally friendly, consisting of 39-49% recycled materials.
- Much smaller and fewer injection holes.
- More evenly distributed material once injected underneath the concrete. Poly starts out as a liquid before turning into a foam which will fill all voids underneath concrete. Mudjacking slurry forms small pads below the injection hole and leaves voids between injection holes.
