Slab Lifting & Leak Sealing

What Causes Concrete Slabs to Settle?

Fundamental to healthy concrete is a solid substrate—well-compacted soils provide a foundation upon which concrete structures perform. Over time, forces of nature take their toll. Decomposing soils, erosion and ground water migration break down this foundation. This is the root cause for concrete slabs to sink or settle.

To Cure the Problem, Eliminate the Cause.

Injecting polyurethane resins into loosely consolidated soils, voids and water pathways will strengthen the earthen substrate and provide watertight encapsulation. With the soils consolidated and stabilized, concrete slabs will provide service for decades.

Our Services

Precision Lift from Prime Resins targets the causes of settling and creates long-term advantages:

  • Erosion Control
  • Soil Stabilization
  • High-Strength Void Fill
  • Precise Slab Lifting

​Why Precision Lift?

Precision Lift® targets the cause so the cure is long-lasting and at a fraction of the cost of slab replacement. At a minimum, concrete settlement is a nuisance and an eye sore. Uneven slabs are trip hazards and a threat to health and safety.

Now your fist choice solution is also the fastest and most affordable. Concrete structures need Precision Lift.

Precision Lift® is designed and manufactured by Prime Resins, Inc., a 35+-year veteran of the polymer industry with customers worldwide. For background information on this product and company, go to

The Precision Lift® system is equal parts art and science. The high-strength polymer is scientifically formulated to strengthen soil conditions and hydraulically lift concrete slabs. The art of the injection grants the precise lifting accuracy and restores safety and beauty to your concrete structure.

As experts in lifting concrete, our objective is to limit your inconvenience and return the safe use of your property.

Features of this Technology

There are many types of leaks, and we offer different solutions to address each of them. We have a full range of products to seal leaks of all types and sizes. These products range from cutting-edge acrylate resins to hydrophilic and hydrophobic polyurethane grouts. Let us maximize your efficiency: one of our technical consultants can advise you on the best product and approach for your particular job.

There are several factors to consider when choosing how to seal a leak, including:

  • Volume of leak, weeping to gushing
  • Size of crack or defect
  • Accessibility of the site
  • Environmental conditions
  • Expansion rate, set time, and viscosity of the grout
  • Physical properties of reacted grout — foam vs gel, rigid vs flexible
Whether your job involves a treatment plant, manhole, culvert, leaking dam, or underground wall, we have what you need. Is potable water involved? Several Prime Resins products have been independently tested and verified to meet NSF/ANSI Standard 61 for contact with drinking water, making them ideal for water treatment, transport, and storage structures. This eco-friendly designation also makes these products a great choice for work on seawalls and near wetlands or other environmentally sensitive areas.

Soil Stabilization

Well-compacted soils provide a foundation upon which concrete structures perform. Decomposing soils, erosion, freeze-thaw cycles and groundwater migration can break down this foundation. This is the root cause for the damage or failure of structures from buildings to highways.

Stabilizing soil can be done without major excavation. Injecting polyurethane chemical grouts and acrylate resins and gels into loose or less dense soils, voids, pores and fissures will strengthen the earthen substrate and provide watertight encapsulation.

Prime Resins has been providing soil stabilization solutions for more than 30 years with our Prime Flex polyurethane foams and gels. We now have acrylate resins to add to your repertoire of options.

The alternative solution is often repair or replacement that can be expensive and might not be feasible because excavation is impossible or too disruptive.
