TERRATHANE LIGHTWEIGHT FILL SYSTEMS
These specially designed and field proven TerraThane polymer systems are used when a lightweight spray or injection fill is required over conventional lightweight concrete mixes, or polystyrene blocks. High strength, low density, slower reaction time, low exotherm and fast application make this the system of choice when filling utility trenches, expansive void area under concrete slab sections or filling expansive areas with already loose, or questionable, soil load bearing characteristics. Can also be used for undersealing and stabilizing joints on rocking slabs from slab curl.
Geotech Services Group provides a cost effective and efficient Soil Stabilization services to our residential, commercial, industrial, municipal and DOT/Highway customers facing settlement problems. We have choices of single and plural component polymers to stabilize weak soils and to improve geotechnical properties such as compressibility, strength, permeability and durability. All of these factors are taken into consideration when the available soils are not suitable to carry the structural loads of the roadway or the building foundation.
Let us help you with your settlement problems!
Geotech Services Group offers clients soil stabilization services using the deep injection process with both single and plural component polymers injected deep into weak soils. The deep injection process is an engineered solution for unstable soil zones and are common culprits for concrete failures.
This deep injection process using 2-part polyurethane foam was protected by patents until recently. Prior to the patent expiring, non-exclusive contractors were only able to use single component polymers. The deep injection process is performed by inserting probes to predetermined depths and injecting two part polymers to effectively “densify” soils at depth through displacement of soils by material volume.
The use of use of plural component expansive polymers for soil and structural stabilization has been around for over 20 years. It can be a very effective way to provide non-invasive “no-dig” stabilization. Deep injection is the installation of polymer material at prescribed depths for the purpose of increasing the density of soils which under sufficient load are capable of bearing that load. The process can also be used to “de-water” highly saturated soils through the displacement of water by compaction and volume replacement with polymer material.
Deep Injection should be considered when testing has been performed that identifies a soil strata lacking the level of compaction necessary to support overburden and structural load. This determination is made through testing by soil sampling and/or Dynamic Cone Penetrometer testing and conducted by a Geotechnical Engineering firm. Each project is unique, and based upon results of the DCP testing a plan is formulated for the injection points, injection depths and injection spacing along with validation testing of injected area by DCP testing.
