Top-Seal ^® From Soils Control International

TOP-SEAL^® is an environmentally safe, general purpose liquid soil additive that is mixed with water and used for controlling and managing a variety of soil conditions. When properly applied in sufficient quantities, Top-Seal will effectively eliminate or prevent the following problems: base failure of paved and unpaved roads, dust pollution, soil erosion, and loss of water from ponds and reservoirs. The various versions and applications for Top-Seal are described below.

Brief note, You may notice that we offer only one product for dust control, soil stabilization, erosion control and soil permeability applications. This is because our product works for all these applications and we don't feel it is necessary to confuse the situation by labeling our product with various names.

STABILIZATION OF UNPAVED ROADS and DUST CONTROL. Using plain water to stabilize unpaved roads and to control dust is a never-ending formidable task that offers little more than a few hours of return on an expensive investment. The futility and frustration of wasting time, money, and precious water resources is increased as the water quickly evaporates and new clouds of pollution are again released into the environment. Fighting dust pollution with plain water is a wasteful outdated method of dealing with a problem that is more easily and less costly solved with an initial application of Top-Seal, and occasional re-applications as needed. Top-Seal application rates for dust control can be varied to meet proper requirements for all traffic situations.

Haul Road Dust Control and Other Heavy Traffic Areas. A special SCI program, known as HR-TS™ (Haul Roads with Top-Seal) is dedicated to controlling dust on roads with extremely heavy traffic. This program will yield permanent and guaranteed results when using Top-Seal as prescribed by SCI. The success of this program with Top-Seal (under a different label) was featured on the cover of internationally distributed Aggregates Manager magazine. The magazine article revealed that this product provided superior performance under very heavy traffic conditions. The HR-TS™ Program is ideally suited for controlling dust pollution in quarries, mines, airfields, large truck parking lots, industrial zones, forests, and military staging areas.

SEE THE TOP-SEAL DIFFERENCE. The photo of the road featured on the left was taken approximately 6 years after completion of construction. The lower section had been stabilized with Top-Seal. The upper section was not treated with Top-Seal, and it shows that the wearing lanes are dark and worn out as a result of a general failure of the base. As the untreated section continues for approximately a mile, there are many patches where potholes and cracks had occurred. The Top-Seal section, stretching for a mile in the opposite direction had no potholes or cracks and it remained in that condition for several years afterwards. Top-Seal is an excellent choice for stabilization of paved surfaces.

BASE STABILIZATION of PAVED ROADS. Top-Seal is used for stabilization of any type of soil base for which a wearing surface has been prescribed. This includes roadways, parking lots, airfield runways, and any other type of traffic area that will be covered with asphalt, chip-seal, or even concrete. When Top-Seal is used properly in sufficient quantities, road base strength will be significantly increased, and penetration by moisture will be greatly reduced. Top-Seal is ready to drive on within minutes of the application yet with time just get stronger as depicted by the chart (right), laboratory testing has revealed that the presence of Top-Seal in a soil sample can increase the strength by as much as 3,000 percent in just a few days! Please contact SCI for more information on guaranteed performance with Top-Seal

EQUIPMENT and CONSTRUCTION PROCEDURES. Top-Seal is easily accommodated into routine construction procedures with no requirement for special equipment or handling considerations. Typically, all that is needed is a motor grader, water truck, and a compactor that is suitable for the type of soil being treated. During application into the soil, Top-Seal is simply diluted with water and distributed into the area of coverage in sufficient quantities to bind and transform a traffic base into a solid mass of tightly cemented soil particles. After a wearing surface is applied over a Top-Seal stabilized base, the life-cycle of the road will be significantly extended and the cost of maintenance and reconstruction will be greatly reduced.

CEMENT BASED STABILIZATION. Field testing by the Texas (USA) Department of Transportation has revealed that Top-Seal strength capabilities are comparable to cement stabilization at a significantly lesser cost. The amount of cement can be reduced by as much as 50 percent when supplemented and stabilized with Top- Seal in a soil base. Most importantly, the performance of the cement will be greatly enhanced while saving as much as 40 percent in the process. The plasticity characteristics of Top-Seal also help create a more flexible base with the cement. This will create a lower threshold for fracturing of the cement and it will lead to a significant reduction in the cost of maintenance.

The core sample, on the left, contains Top-Seal and cement The sample was taken from a road stabilized by the Texas Department of Transportation (TXDOT) in East Texas, USA. TXDOT tests revealed that Top-Seal alone produced greater strength in a road base than a cement only section in the same road. However, when combining the two products together, superior results are achieved with an even greater savings

STABILIZATION of LANDFILL LINERS and SOIL EROSION CONTROL. Top-Seal has a tremendous capacity for making soil virtually impermeable. The graph compares the US EPA permeability coefficient of 1x10-7 for land fills with the laboratory confirmed permeability coefficient for Top-Seal of 2.9x10-9. Top- Seal meets and exceeds the US EPA standard many times over, thereby establishing itself as a superior additive for landfill composite liners. The composite liner of a landfill, or any soil embankment containing Top-Seal will be transformed into a solid membrane that will seal itself against liquid penetrations. Substandard soils, that would otherwise be excavated and replaced, can be treated with Top-Seal at significant savings for landfill owners.

AGRICULTURAL APPLICATIONS. Top-Seal is an agriculturally friendly additive that promotes healthy growth of produce at a cost savings that pays for itself many times over. The environmentally safe applications of Top-Seal on farm and ranch roads will virtually eliminate the hazards of dust pollution in areas where crops and livestock are raised. When crops and farm animals are rendered free of dust pollution, they are cleaner and much less affected by the deteriorative invasion of airborne bacterium. The livestock remains healthier, and the crops receive more sunlight as a result of the absence of dust pollution.
