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.

They can be fixed through Polyurethane Foam Injection (Polyjacking), Mudjacking, Grinding/ Resurfacing, or Full Concrete Replacement. Polyjacking is a preferrend method as it’s half the cost of replacing and with the aesthetic issues of grinding. Polyurethane Foam Injection starts with series of holes being drilled through the concrete. Grout or foam is incrementally injected under the slab to build pressure and manipulate the slab into place. Specialized equipment and expertise is required to raise concrete.
Settled concrete should be raised if it is causing improper drainage, creates an uneven surface creating a tripping hazard or causes structural damage. Complete slabs or slabs cracked into large pieces can often be raised. Shattered concrete should be replaced.
Polyurethane Foam Injection: 20 years or more, Mudjacking: 5-10 years (depends on soil conditions and water exposure). Keep in mind, raised concrete is only as good as what supports the slab. A raised slab of concrete could resettle if the cause of the settlement is not address. This could be improper drainage, weak soils or overburdened slabs. Raised slabs can stay in place permanently or require periodic maintenance if the cause of the problem is not addressed.

Site accessibility, weak soils supporting slabs, improper drainage, and heavy loads can challenge concrete raising projects. With the right strategy, equipment and material these challenges can be overcome. Even a restricted slab that cannot be lifted, can still be stabilized by improving the soils below. After the slab is supported, cosmetic repairs can be made.
Raising concrete with mud re-introduces a soil-like material under the slab. Materials are locally sourced. Material are mixed with water for a variety of consistency and often mixed with Portland cement to improve the strength. Mudjacking introduces this grout under the slab through 1”-2” holes. Like soils, mudjacking material is heavy and could erode.
Polyurethane foam is injected under the slab through smaller 3/8”-5/8” holes. Polyurethane foam is a strong lightweight material that is injected as a liquid that develops into foam. This foam develops within the soil, creating a strong soil/foam matrix. HMI manufactures a variety of polyurethane foam formulas with various reaction characteristics to fit many applications. Materials are lab tested, certified and have technical data available for engineering requirements.

HMI is a great way to expand your business with concrete lifting.
Mudjacking is a great add-on business. HMI can provide you with the equipment, training, and support to make any expansion successful.
Contractors:
Landscaping, spray foam, general, concrete and specialty contractors often have some of the tools needed to start raising concrete. In this case, a contractor looking to expand their business will be provided with a customized system quote with only the equipment and tools they specifically need to start concrete lifting. A spray foam contractor may only need small tools and material to start concrete lifting with polyurethane, while a concrete contractor may only need a mudjacking pump to have all the equipment necessary to expand their business.
Raising Concrete Can Be Tricky, Let HMI’s Experience Answer Your Questions
Support is available Monday-Friday from 7:00 a.m.-5:00 p.m. We are staffed with people who have actual on-the-job experience raising concrete. They can answer questions and solve issues with troublesome jobs or how to bid on a certain concrete raising or void filling project. Applications and pricing are covered in detail during HMI 2 day training events.
Polyurethane Foam Systems and Hydraulic Mudjacking equipment. A variety of systems configurations are available for various applications, scope of work and budgets. Stand-alone, trailer or truck mounted systems are available.
HMI is Your Best Option for Slabjacking Equipment, Systems and Material. Made for a conctactor BY a contractor.
HMI has been setting the standard for slabjacking since 1974. Not only do we manufacture the equipment, HMI uses and tests it on a daily basis. Perfecting the standard and innovating tomorrow’s advances, HMI offers all the benefits of a franchise without the fees, royalties, and territory restrictions commonly associated with franchise opportunities.

Lifting concrete instead of replacement is a fast and cost-effective alternative. This process avoids tearing out the old concrete and disposing of the waste and cuts down on the heavy machinery and transportation needed. HMI polyurethane materials do not contain VOCs and are manufactured with renewable materials achieving USDA Biobased certification.
Spray foam insulation contractors use similar equipment for polyurethane concrete lifting
There is however, specific material and equipment necessary to start using this equipment for concrete raising. Everything necessary to begin raising concrete with existing spray foam equipment is available from HMI in the Concrete Raising Conversion kit.
