Polyurethane foam concrete raising and mudjacking are two methods used to raise and support sunken or unstable concrete  slabs by drilling holes and pumping material under the slab. 


 Slabjacking is a term used for both methods.

Polyurethane foam concrete raising and repair uses a foam material that is injected under the slab.  When the components of polyurethane are mixed, a reaction causes the material to expand.

By drilling small holes and pumping material under the concrete slab, expanding foam fills any voids beneath the slab to raise and level the concrete.

Why does concrete settle?

Many factors are involved in settling concrete:


  • Poor Soil Conditions.  Clay-rich soils expand and contract with moisture  content.  As soils become saturated with water, clay expands and loses its strength, allowing slabs to sink.  Often heavy rains, melting snow, and plumbing leaks can result in a sunken slab.


  • Compaction. Many homes are built on back filled soil.  If soil is not compacted correctly, back fill will slowly and unevenly compact, allowing slabs to  settle.


  • Tree Roots. Trees and large shrubs can consume tens of gallons of water a day.  Loss of water in soils located near concrete results in settling of slabs.


  • Erosion. Improper drainage, including misplaced downspouts, can cause soil instability by creating areas of saturated soils, allowing slabs to settle.

What is Polyurethane Foam?

We only use polyurethane foam concrete raising on our jobs for concrete repair.  We have formed a relationship with HMI Company in Manitowac, WI, innovators in concrete leveling products.  We only use polyurethane foam produced by HMI.  


HMI  has developed revolutionary foam that is setting new standards in polyurethane foam quality.  HMI is the only company that makes  polyurethane foam from recycled material. ASTM,  an international technical standards organization, has tested this recycled material and has deemed it the best foam available for raising  settled concrete


Recycled foam offers:

  • Fast tact-free time, expands within 10-15 seconds
  • High compressive strength lift
  • No concrete adhesion
  • Fast and aggressive expansion 
  • Delayed cure time for slab manipulation assuring perfect fit


 Reclaimed  foam is used to manufacture plural component foam specifically designed  for applications like lifting, high density lifting, stabilization, and  under sealing.   


Benefits of Foam

 Benefits of leveling concrete with polyurethane foam  include:

  • Cost-effective
  • Clean work environment
  • Small drill holes
  • Lightweight
  • Environmentally friendly
