The original term mudjacking comes from using topsoil mixed with cement (mud).  However, topsoil has organic properties that will eventually break down and may cause the concrete slabs to resettle.  The most readily available material throughout the country is agricultura

Concrete Raising is Also Known as Mudjacking, Slabjacking, Pressure Grouting, and PolyJacking
Also known as slabjacking or pressure grouting, mudjacking is the process of pumping material under a sunken slab of concrete to lift it.  Other uses include joint stabilization or filling voids to support the weight of a concrete slab.  On residential, commercial, and municipal levels, raising concrete is a cost-effective alternative to replacing concrete typically saving 30-50%. The best way to recycle concrete, mudjacking will avoid the cost of demolition, removal and landscaping.  There are two types of concrete lifting, polyurethane and traditional mudjacking. Receive a free catalog!

Can polyurethane set up, lift concrete and maintain its compressive strength when pumped under slabs where water is present? At HMI it can!

RR401g is the latest HMI innovation in perfecting specialized foams for residential, commercial and DOT contractors who lift and level concrete slabs. This 3-4 pound hydrophobic/hydro-insensitive foam is again a two component polyurethane foam product, best delivered by HMI equipment, which sets up, lifts concrete and maintains compressive strength even when a void is filled with water. Weather and draining are no longer concerns for contractors or government crews. Traditional delays and costs in completing projects are gone.

Commitment to Innovation Is More Than A Tag Line At HMI!

A stroll through any book store will bombard you with scores of business books about  “must know” techniques, processes and strategies. We sell a turnkey business package and recently began thinking about the common traits of our most successful customers. Despite an effort to put the ideas in fancy “hot” business terms our conclusion was the secrets of success are:

1)    Learning From Mistakes

2)    Logically and Systematically Solving Problems

3)    Interfacing with People  

With more than a half century of business experience behind us we then benchmarked the above list against our successes and failures. Despite economies, technology, and market circumstances and other changes we realized we were successful when we we

Last night I listened to President Obama announce the pending return of tens of thousands of young Americans who risked their lives to protect us. This morning I heard the featured news story about the high unemployment of Persian Gulf Veterans.

I remember the Vietnam era and the plight of returning Veterans of that time. Unlike that period, it appears to me that our country is rallying around the troops irrespective of political perspective. My chest swelled recently when I was in an airport and watched a citizen walk up to soldier traveling in uniform and say, “thank you for everything you are doing for us!”

The experience in that airport motivated me to create and announce the HMI Veterans Career Transition Program. Simply  stated w

“How you get the work has changed as much as how you do the work!”

As I was sitting back and observing the recent April HMI Training Seminar, two thoughts came to mind:

1.      How you get the work has changed as much as how you do the work!

2.      When you consider; marketing, estimating, and sales HMI devotes as much time in our seminar on getting the work as we do training future equipment owners on how to do the work!

More than 3 decades ago I started my mudjacking business by putting a 2’x4’ ad in the local newspaper. That one ad generated 14 requests for estimates and my first 10 jobs. RaiseRite/HMI was born and I had a new career. For the next 10 years, newspaper advertising was the anchor to my marketing program.
