Deep Horizons Injection Grouting provides a proven, cost-saving approach to expensive sink hole repairs, pipeline leak sealing, soil stabilization as well as seawall, foundation, dam and levee repairs.

Our patented technology and delivery method of soil stabilization has been tested and verified at depths in excess of 100′.

We are eliminating the limitations of injection grouting to successfully address aging infrastructure’s challenging projects at depths never before possible.

Deep Horizons Injection Grout technology (DHIG) combines the benefits of deep compaction cement grouting replacing the injected material with chemical polyurethane.

DHIG offers federal, state, county, city, municipalities, and commercial contractors the benefit of providing an eco-friendly, sustainable, and permanent water-resistant solution for half the cost associated with cementitious grout, in a third of the time, and with minimal traffic diversion.

PLUS, it delivers an environmentally safe and sustainable alternative to costly dig and replace methods or when existing trenchless technology methods have limits which make them an impossible viable solution.

On Stable Ground: A Singular Solution

Soil instability and displacement have all sorts of unpleasant causes — and effects. From leaking sewer pipelines and sinkholes to catastrophic dam or levee failures, the ground beneath our feet is riddled with potential problems and hidden dangers.


Polymer Technologies has patented the System and Method for injecting dual or multiple component polyurethanes at depths far exceeding the industry’s 20-foot below-ground surface threshold whether in wet or dry conditions.
Our technology is designed to inject and mix these components in the ground, at the source problem, and from the bottom up to the surface thus allowing maximum vertical and horizontal migration to fill voids, seal leaking infrastructures, and compact weak or fractured soils, while stabilizing adjacent eroded soils.


Thus far, Polymer Technologies has injected dual component polyurethane at depths up to 100 feet below ground surface under aggressive temperatures of 140 degrees without abandoning the injection point. In other words, materials continue to inject while the casing is removed from the bottom up to the surface level. The materials are combined at the tip of the drill thus allowing the reaction to take place at the source of the problem (in the ground at the bottom). This allows the reactive materials to permanently seal leaking pipes or storage tanks causing environmental issues, stabilize surrounding contaminated soils caused by the leak erosion, fill voids with expansive foam while permanent liquefaction takes place providing a water-resistant solution.

How We Achieve This

  • A channel is introduced vertically, horizontally, or angled to the problem area.

  • A guide tube is inserted through the channel.

  • The mixing device is fed through the guide tube and locked into the base.

  • Components are independently delivered to the mixing device allowing the reactive material to migrate vertically and horizontally.

  • The casing is lifted incrementally when injection pumps begin to labor.

  • The materials continue as the section by section of guide tube is removed until reaching the surface or desired lift is achieved.

  • This process is repeated every 10-25 feet (depending on soils conditions) until the desired outcome or area has been mitigated.

End Costly Infrastructure Repair Method Limitations

Deep Horizons can save you MONEY, TIME and Disruption to your community by enabling quick remediation of serious infrastructure issues never available before and at a fraction of the cost of dig and replace.


What is the advantage of Chemical Grout (Polyurethane)?2022-12-27T12:25:46-05:00

A key advantage of chemical/ permeation grouting is the ability to transform granular soils into sandstone like masses by filling the voids with a low viscosity, non-particulate grout with little to no disruption to the soil.

Is this system more cost effective?2022-12-27T12:26:31-05:00

It certainly is because it does not require demolition and is significantly less labor intense. A simple 3″ diameter drill can cover an area up to 30 feet in diameter.

What is the delivery or application method?2022-12-27T12:27:24-05:00

NSF Approved two-part polyurethane material is delivered via a small 3-inch diameter drill made to reach the desired depth and mixes at the tip. The material hardens within seconds and fills the void. A single perforation can apply material to an area of 10′ to 30′ in diameter.

What makes this so different from other current delivery or application methods?2022-12-27T12:28:30-05:00

Cementous grout can only be delivered at depths below 20′ and polyurethane (foam) can only be delivered up to 7-20′. Our delivery method ensures that we reach the desired depth and does not allow the material to harden before we reach the affected area. This technology can be used not only to fix sinkholes but also fix dams, levees, canals, embankments, landslides, and tunnels with fast-action polyurethanes.

How long does the process take?2022-12-27T12:29:00-05:00

Every project is different and depends on the soil condition. However, due to the fact that there is no demolition required, this method can be delivered very quickly. Also, because our product reacts (hardens) within seconds (even in the presence of water and other solutions) the area is ready for traffic by the time we leave the premises.

Is there a specific material needed to be injected?2022-12-27T12:29:37-05:00

Absolutely not. In fact with polyurethane injection delivery, the engineers have the freedom to select the product or combination desired, depending on the soil condition and properties of the material required.

Is this process environmentally friendly and safe?2022-12-27T12:30:13-05:00

Yes indeed! This system is less destructive and more environmentally friendly than any current method.

1. Current (fast reaction injection delivery used for less than 10′ deep) uses tubes that cannot be recovered and must be cut at the surface and left buried. With our delivery method, the tubes used for injection are recovered.

2. The use of mortars and grouting suspensions are dangerous to the environment because the toxic components can pollute the karst aquifer and cause long-lasting hazardous impacts on underground species.

Sarasota, Florida

Lift Station 87 is a project that was under construction that will eventually handle approximately 1/3 of the City of Sarasota’s waste water flow. Lift Station 87 was to replace Lift Station 7 that was in service at the time. The station forwards the effluent to the City’s waste water treatment facility. The influent line is a 36” diameter line that crosses Hudson Bayou. While testing the influent line, City staff discovered significant ground water intrusion into the line. The intrusion into the line was discovered to be through several holes, breaks, and joint failures. These intrusions will cause the sanitary system to work harder thereby reducing the useful life of the equipment and consuming additional energy for those efforts.

The first repair effort was to install a liner inside the pipe and impregnate the line with epoxy. While this type of repair has worked in similar type projects, it failed to stop the water intrusion.

The second repair effort to repair the pipe involved the injection of a two component, fast reaction chemical grout. The intent was to seal the pipe from the exterior, in-situ. Due to the methods used, previously referred to as ‘historic method’, the efforts failed. The reason for failure can be attributed to the depth of the pipe being greater than 20 feet.

The third repair effort that was considered was to excavate the pipe and replace it. This effort would have caused extensive disruptions to the surrounding infrastructure and to the local population. This option was estimated to add an additional $9-12 Million to an already over budget project, not to mention extending the completion time of the project approximately another year for the already severely delayed project.

Instead of opting to delay and add additional cost overruns to the project, the City took a chance to engage Polymer Technologies Worldwide, Inc.’s patented process. Not only did the efforts seal the pipe leaks, the foundation of the lift station structure was enhanced and further stabilized. The Polymer Technologies Worldwide materials were put into place while the construction of the lift station facility continued.

By the City utilizing these efforts, there was no additional time delay, there was no adverse impact to the motoring public, and there was not multimillion dollar cost overrun.


We look forward to hearing from you and learning about your infrastructure projects and how our technology can be applied to help you save money and time and gain peace of mind.
