Below are the advantages of the polyurethane method used today in concrete leveling:
Cheaper than other methods
Since the concrete does not have to be removed or replaced, this is 75% cheaper. The cost of removing and replacing, as well as the longer waiting period, drives up cost significantly.
This method is 80% more efficient in terms of work time and curing time. The materials used will harden in minutes which mean the project can be completed in a matter of hours instead of days. This make concrete services provide completion of project faster.
Much Less Down-Time
Due to the fast acting materials there is no longer a need to stop the usual work flow for days or weeks on end. The project can be done in a matter of hours, enabling people to get back to their usual work quickly.
Polyurethane is known for its compressive strength which results in solid and dense products. But another surprising feature is that it is also a flexible material. Its tensile strength and elongation properties allow pliability making it tough yet flexible for demanding conditions.
High-density polyurethane expands 20 times its liquid volume and fills up spaces wherever it is poured. It also takes on the shape and size of those gaps which completely supports the pavement with precision.
Ability for compaction
Since the material is able to fill-in subspaces, it bleeds into the sub base and actually binds soil, rocks or loose concrete. This adds more strength to the substrate and therefore increases the durability of the floor's surface.
Material is lightweight
Polyurethane material only adds 3-5 pounds per cubic foot to the sub base compared to the 100 pounds or more that mud jacking grout may add.
Concrete pavement injection holes are only 5/8” in diameter which is lesser than the diameter of 3” or more that other methods require. The method is easier for concrete services providers to use.
Resistant to moisture
Most polyurethane materials are designed for wet conditions. They have hydrophobic properties which displace water in the sub base. Being that the material is not affected by moisture, as long as the substrate is prepped correctly, no adverse reaction should arise in conditions where moisture is commonplace.
With all the above reasons, those who use high-density polyurethane for concrete leveling can expect infrastructure reliability for a long time. This saves time and money. Concrete Restoration providers such as Champion Coatings are familiar with such techniques and are qualified to handle your project's needs.
