TOP-SEAL WHITE TM   Liquid sealant is used for soil stabilization, dust control, and erosion control for roadways, parking lots, airfields, runways, embankments, and road shoulders.

​

Base stabilization:  Department of Transportation field-testing revealed that TSW’s strength capabilities are comparable to cement stabilization. Other tests have shown that U.S. environmental standards are met and exceeded with TSW applications. TSW is easily accommodated into routine construction procedures with no requirement for special equipment or handling precautions. The product is simply diluted with water and distributed into a soil base in sufficient quantities to bind and transform it into a solid mass of tightly cemented soil particles. At a fraction of the cost of cement or lime stabilization, TSW is significantly more cost effective for stabilization of paved roads.

​

Stabilization of unpaved roads & controlling dust pollution:  Many unpaved roads throughout the world have been improved with TSW. The product is simply added to water and distributed into a road base during normal construction or reconstruction operations. A final overcoat is applied as a finishing touch, and with occasional maintenance applications, a road will remain permanently stabilized and free from dust pollution. In the end, there is a tremendous savings by eliminating the need for asphalt or other types of wearing surfaces, and by the reduction of maintenance repairs or reconstruction efforts. For haul roads and heavy traffic, please refer to product HR-TS ™.

​

Recycling old asphalt roads is one of the best uses for TSW. The product is environmentally safe, and therefore, is an excellent alternative to the increasingly unfavorable method of depositing more petroleum-based products into the environment. The Texas Department of Transportation has used TSW as the primary additive for cold in-place cycling of old asphalt roads. The results of pulverizing asphalt and mixing it with its old base are dramatically enhanced by the introduction of TSW as a superior stabilizer that will tightly bind it all together. There are significant advantages in using TSW in the renovation of old asphalt roads. It's easier to apply, has superior binding capacity, no special equipment or heating tanks are required, and no special handling procedures are needed. Probably the most important benefit from using TSW with old asphalt is that the process of the much more expensive option of excavating and disposing of the old asphalt in accordance with very strict environmental laws can be completely eliminated. Overall, a tremendous savings and superior performance can be expected from using TSW in the recycling of old asphalt roads.

​

Stabilization with cement and TSW. The amount of cement in a soil base can be reduced by as much as 50 percent when supplemented and stabilized with TSW, and the resulting performance can be equal to or greater than the cement alone. Most importantly, a savings of as much as 30 percent can be achieved in the process. The plasticity characteristics of TSW will help create a more flexible base with the cement, thereby, reducing the threshold for fracturing and resulting in a significant reduction in the cost of maintenance. Texas Department of Transportation laboratory testing has revealed that the strength characteristics of TSW are comparable to cement in similar soils.

​

Stabilization of landfill liners and soil erosion control:  TSW has a tremendous capacity for making soil virtually impermeable. It is the clear winner in a comparison between the US EPA permeability coefficient of 1x10-7 for landfills and the laboratory confirmed permeability coefficient for TSW of 2.9x10-9. TSW meets and exceeds the US EPA standard many times over, thereby establishing itself as a superior additive for landfill composite liners. When used in landfills and for soil erosion control, TSW is transformed into a solid membrane that will seal itself against liquid or moisture penetration. Substandard soils that would otherwise be excavated and replaced can be treated with TSW at a tremendous savings in landfills, embankments, and reservoirs.

Equipment and on-site assistance:  There are two phases, an initial application and the maintenance program. The initial application produces immediate results with a substantial amount of the product. The higher dilutions during the maintenance phase allows the product to penetrate more effectively into the previously hardened road base as it tackles newly worn areas or areas with new contamination blown in by the wind or carried in by haul trucks. We supply free on-site technical assistance for new customers. Hot-line assistance and continuous monitoring of dust pollution levels are available from Terra Pave International’s main office at all times. Reports will be provided as needed.
