Polymer Technology

Polymer Technology USA is the only company worldwide to successfully address the unstable, sub soil conditions, using Polymer Technology in excess of 7-10 feet of depth. Not only for repairs in wet or dry conditions but also for Environmental Containment purposes.

Polymer Technology USA is owned and operated by an inventor of proprietary intellectual property  patent # US 9,790,655 (Mixing Device Method for Silt Fine Soil and Soil Stabilization). This proven delivery method of soil stabilization utilizing polymers has been tested and verified at depths in excess of 100′.

Current Grouting Methods

Traditional Grouting:Grouting is a procedure in which grout is injected into different kinds of spaces. This procedure has had broad applications in modern civil engineering, especially in karst terrains, for nearly 200 years. Ingredients for the preparation of mortars and grouting suspensions include cement, clay and fillers, bentonite, asphalt, additives for stability and water.

Current Limitations:The hydrostatic pressure in the soil increases to higher levels with compaction grout. The highly disruptive hydraulic gradients accelerate the dissolution and expansion of fractures and bedding planes beneath the surface by several orders of magnitudes. As a result, intolerable leakage of karst reservoirs can occur over the lifetime of the landscape. In addition, some ingredients and chemicals used in the preparation of mortars and grouting suspensions may be toxic, neurotoxic or carcinogenic, and may be irritants or corrosives. Their use is dangerous to both humans and the environment. The toxic components can pollute karst aquifers and cause long‐lasting hazardous consequences on karst underground species. Both physically and chemically, this material voraciously and quickly destroys underground habitats and kills an enormous number of rare, endangered and endemic species.​

Polyurethane Grouting: This is the process of injecting expanding polyurethane grout into voided areas or directly under roadways, inside structures or under slabs-on-grade in order to fill voids or relevel slabs.

Advantages: There are lots of advantages to polyurethane grouting as compared to other methods of repair, such as slab jacking, grinding & replacement.  Used mostly in infrastructure and industrial markets for many jobs, such as, lifting and stabilizing interior floors, Polyurethane Grouting is almost unquestionably the best repair process available.  Polyurethane grouting is:

  • Cleaner: Polyurethane grouting is the cleanest concrete lifting and stabilization process.  Because the injection equipment is mechanically connected to the slab or structure, no loose material is introduced to the repair area.  Dustless drilling is easily accomplished, and even non-dustless drilling is essentially mess-free due to the small hole size.  There is no grout or mud to track around job sites.
  • Less Disruptive: Polyurethane grouting is the quietest and fastest process for stabilizing and raising settled concrete slabs.  Because of the small hole size, drilling is fast and quiet, and there is virtually no noise associated with the injection process itself.  The equipment for polyurethane grouting is self-contained in a box truck, which is typically parked away from the direct work location.
  • Immediate Traffic: Foot traffic during work is functionally OK, and immediate resumption of vehicular traffic after work is completed can be expected. 
  • Fast: Polyurethane grouting crews can lift up to 12 times faster than standard slab jacking or mud jacking crews in many situations.  Because of the small hole size and ability to lift larger areas per hole, polyurethane grouting is much quicker than slab jacking. 
  • Lightweight: Lightweight material reduces the overburden on underlying soils, reducing the chances for resettlement.  This reduces the amount of additional burden weight placed on the underlying soils.  Geotechnical polyurethanes are an excellent choice for lightweight fills, because of their exceptionally low unit weights (down to 2 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.
  • Current Limitations: Due to its inability to go beyond 7-10’ , polyurethane grout is often used in concert with compaction grouting whereby compaction grouting is used to densify the soil at depth where consolidation may be occurring leading to surface settlement, and polyurethane grouting is then used to relevel slabs on grade and fill any existing voids, or voids created by the releveling work.

Our Innovative approach

Using our experience in over 700 successful sinkhole repairs we developed and patented a new delivery method that mixes a two-component polymer mixture at any depths (currently tested up to 100’). This method provides significant advantages because UNTIL PRESENT DAY, a combination of these techniques were required to treat both the cause (by the densification of loose soils) and the symptom (by the filling of voids and releveling) of the settlement.In prior years, polyurethane grout was mostly used to fill voids and cracks at or near the surface. Without deep injection compaction grout, helicons, or piers; the substrate level would continue to unravel. Our patented Mixing Device Method for Silt Fine Soil and Soil Stabilization is revolutionary and eliminates the need for these additional costly methods.
