Question 1

What kind of material is used to lift/raise concrete?

Accepted Answer

Richards' LLC uses polyurethane foam to lift and level existing concrete slabs. This material is injected in liquid form and quickly hardens into a rigid foam structure. The foam maintains its density permanently without shrinking over time. Compared to traditional mudjacking materials, polyurethane foam is significantly lighter and requires fewer, smaller injection holes for the lifting process.

Question 2

How much does concrete lifting cost?

Accepted Answer

Concrete lifting typically costs approximately half the price of complete concrete replacement. Most projects range between $2-5 per square foot, with final pricing determined by the volume of polyurethane foam required to achieve proper leveling. Several factors influence the total cost, including the depth of slab settlement, the presence of voids beneath the concrete, and whether additional sections must be included in the repair.

Question 3

Is the polyurethane foam safe?

Accepted Answer

Richards' sources polyurethane foam directly from the manufacturer located in Manitowoc, Wisconsin. The patented formula is developed by in-house chemists and specifically engineered for concrete raising, leveling, and stabilization applications. Each batch is freshly manufactured upon order and shipped directly to our team. The foam composition includes 39-49% renewable and recycled materials, making it the most environmentally responsible polyurethane foam available. Importantly, the formula contains no toxic chemicals.

Question 4

So, you say concrete lifting is environmentally friendly?

Accepted Answer

Yes. The polyurethane foam we use contains 39-49% renewable and recycled materials, representing the most environmentally sustainable option in the concrete lifting industry. The formula is free from toxic chemicals. Beyond the recycled content, our manufacturer reports that more than 100,000 concrete slabs have been preserved rather than sent to landfills through this lifting method. Choosing concrete lifting over replacement saves you money while contributing to environmental conservation.

Question 5

Is maintenance needed after the lifting?

Accepted Answer

Following completion of our concrete lifting work, customers are responsible for sealing the seams between repaired sections with caulk and backfilling any exposed areas to contain the material. Preventing water infiltration beneath the slab is essential to maintaining the integrity of the repair. Proper water management includes ensuring downspouts are positioned to direct water flow away from your concrete surfaces and foundation.

Question 6

What areas can benefit from concrete lifting? Where can concrete lifting be used?

Accepted Answer

Richards' provides concrete lifting services for numerous commercial and residential applications to restore safety and appearance to sunken, uneven concrete with voids. Applicable areas include store floors, parking lots, sidewalks, walkways, steps, ADA ramps, roadways, bridges, driveways, patios, garage floors, porches, pool decks, foundation spray foam, and many other concrete surfaces.

Question 7

How does Richards' concrete lifting method with polyurethane foam compare to traditional mudjacking?

Accepted Answer

Polyurethane foam is considerably lighter than traditional mudjacking materials and requires fewer, smaller injection holes. Richards' operates without driving heavy equipment across your lawn or landscaping. Our process involves extending a hose directly from our trailer to the repair location, eliminating the need for any machinery to travel through your yard during the concrete lifting procedure.
