AND GROUT SERVICES
At Superior Grouting, we are committed to providing the best polyurethane grouting in Houston for our clients, including government agencies, industrial facilities, and large corporations. With our experience and qualifications, we have become a trusted provider of polyurethane grouting Houston services, specializing in solving settlement and instability issues across concrete structures, bridges, interstates, and foundations.
Our process involves the injection of expanding polyurethane grouting, which is a cleaner, faster, and less disruptive method compared to cementitious grouting. This modern approach delivers superior precision and long-term reliability, making it the preferred technique used by Departments of Transportation, municipalities, and state agencies nationwide.
Not only is polyurethane injection fast and effective, but it is also economical and environmentally safe. Our team is dedicated to providing value while minimizing downtime, ensuring every project is completed with quality and care.
We specialize in high-performance pressure grouting services designed for government agencies and large corporations. Our skilled technicians use advanced techniques to solve settlement and stability issues, helping clients maintain the long-term value of their assets.
One of the unique solutions we offer involves dual-component polyurethane injection systems that mix and expand under pressure. This high-density foam quickly fills voids, stabilizes subgrades, and re-levels slabs with precision. It’s a reliable and cost-effective solution for foundation repair, soil stabilization, and infrastructure rehabilitation.
Our method offers the same precision and consistency you’d expect from a PU foam injection grouting factory, while remaining fully customized for each job site.
On-site Footprint: Small and compact
Mobility: Crews move easily between locations
Cleanliness: Minimal waste and cleanup
Responsiveness: Multiple teams allow quick scheduling and turnaround

Polyurethane foam injection, also known as PU foam grouting, provides outstanding performance compared to cement-based materials due to its lightweight nature, precision control, and strength. It is ideal for both foundation lifting and polyurethane foam foundation repair applications.
Polyurethane grouting is…
Cleaner -
is the cleanest concrete lifting technique and stabilization process. Because the injection equipment is mechanically connected to the slab or structure, and mechanical seals engage when not injecting material, no material is exposed to the surface or surroundings in the repair area.
Less Disruptive -
is the quietest and fastest process for stabilizing and raising settled concrete slabs/structures. Because of the small hole size 5/8” (size of a dime), drilling is fast and quiet, and there is virtually no noise associated with the injection process itself. The equipment for poly
is self-contained in a box truck or enclosed trailer, which can be parked up to 210 feet away from the injection point.
Immediate Traffic - Foot traffic during work is functionally OK, and immediate resumption of vehicular traffic after work is completed can be expected. Polyurethane foam injection concrete lifting is not affected by foot traffic during the poly injection process. Vehicular traffic may resume immediately after work is completed. This includes heavy loading such as trucks and industrial equipment like forklifts, and even trains.
Fast - Polyurethane grout injection crews can lift concrete faster than standard slab jacking or mud jacking crews. Because of the small hole size and ability to move around quickly, Poly grouting
is much is much more efficient than slab jacking. Because of the equipment design, upon arriving on a job, polyurethane grout crews are typically actively executing the work within 10 minutes of arrival for typical repairs.
Lightweight - Lightweight material reduces the overburden on underlying soils, reducing the chances for resettlement. Even the highest density polyurethane foam injection used for poly grout are significantly lighter than alternative lifting and stabilization materials. This reduces the amount of additional weight placed on the underlying soils. Geotechnical polyurethanes are an excellent choice for lightweight fills, because of their exceptionally low unit weights (2 to 4 PCF) and fast cure times (few minutes).
Waterproof - High density polyurethane is waterproof, so treated slabs are thoroughly undersealed. Polyurethane can also be installed in water, so flow testing or water stop applications with active flows are not a problem. Because of the near-immediate curing, water stopping jobs are fast and easily tested on site to ensure efficacy of the repairs.
There are many times when polyurethane grouting is the only repair process that will address a problem. Here are some of the times when polyurethane grouting is best:
Large Slabs
Large slabs (typically bigger than 100 square feet) are best repaired with
because polyurethane can travel under the entire slab from just one or two injection holes. This creates a more diffuse lifting force than cementitious grout. This speeds up work and lessens the chance of cracking.
Faster reacting lower density foams typically start to expand within a few seconds of injection, so they are good for concrete slab foam jacking. Slower reacting, higher density foams can travel as a liquid for up to 45 seconds before starting to expand and harden. This allows them to lift extremely large areas, as the liquid is injected at 1100 psi, which forces it into what can be very small spaces under the
.
Heavy Slabs
Because of its high expansion force and ability to spread under large areas of slabs and structures before expanding, high density polyurethane, often referred to as
, can lift extremely heavy slabs with ease. These include roadway slabs, bridge approaches, rail crossings and slabs with heavy loads, such as machinery bases and floors with backup battery power packs.
Areas Where Cleanliness is Important
Due to the small, infrequent holes, low dust drilling is easy. Additionally, because there is a mechanical connection between the injection equipment and the slab, no material is exposed to the surface or surroundings. Automatic, mechanical valves on the injection equipment prevent leakage of material when not injecting. We use special dustless drilling equipment for most interior jobs.
Load Sensitive Areas
The most common cause of slab settlement is inadequate compaction or bearing capacity of the underlying soils. Because high density polyurethane is lightweight (typically 2 to 6 pounds per cubic foot), there is very little additional weight transferred to the underlying soil as part of repairs. This helps to minimize the chances of resettlement. Sand-based mud jacking material typically weigh more than 125 pounds per cubic foot. The weight savings with polyurethane grouting are significant.
Remote Sites
Because high density polyurethane is stored and transported as a liquid which then expands. A single truck and 18-foot enclosed trailer can easily transport more than 100 cubic yards of expanded material. The equivalent for slab jacking grout would require more than 6 large dump truck loads and onsite handling equipment. Raw polyurethane material is transported in standard 55-gallon drums. So, it is easily transported, stored and handled on job sites.
