01.What is polymer soil stabilization?
Polymer soil stabilization is a ground engineering technique that uses polymer-based chemical agents — such as bio-enzyme catalysts — to permanently alter the mineralogy of expansive clay soils. The polymer collapses the clay lattice structure, expels moisture, and binds soil particles into a dense, rock-solid, hydrophobic matrix. Permabase Black™ is a polymer soil stabilizer that adds a proprietary carbon-black tint to this process, delivering structural stabilization and a dark asphalt-like aesthetic in a single application.
02.Is Permabase Black a permanent replacement for asphalt?
Permabase Black is a permanent soil stabilizer that provides the aesthetic of asphalt. For low-speed, rural, or agricultural applications — like ranch roads, laydown yards, or rural driveways — it is an exceptional asphalt alternative. For high-traffic, high-speed commercial roads, it should be used as the superior stabilized subgrade beneath a standard wearing course.
03.Will the black tint wash away in the rain?
No. The carbon-black tint is catalyzed directly into the soil matrix alongside the bio-enzyme. Because Permabase creates a permanently hydrophobic (water-repelling) soil structure, the tint does not wash off, leach into the water table, or fade rapidly during rainstorms.
04.Can Permabase Black be used for PM10 dust control?
Yes. Permabase Black is one of the most effective PM10 fugitive dust suppressants available. Unlike water spraying (which evaporates within hours) or oil-based applications (which leach hydrocarbons), Permabase Black permanently binds dust-generating soil particles into a solid, dark, hardened surface that eliminates airborne particulate matter.
05.How does Permabase Black compare to lime stabilization?
Lime stabilization raises soil pH to extremely caustic levels (12+) and requires a separate asphalt or gravel cap since lime does not provide an aesthetic wearing surface. Permabase Black uses a non-toxic polymer bio-enzyme that stabilizes the soil AND provides a finished dark surface in one pass — no additional capping required for low-speed applications.
06.Can Permabase Black be used on expansive clay soils?
Absolutely. Permabase Black is specifically engineered for expansive CH and CL classification clays. The bio-enzyme catalyst permanently collapses the montmorillonite clay lattice, eliminating swell potential and creating a dense, non-expansive, load-bearing subgrade with dramatically improved CBR values.
07.Is polymer soil treatment safe near water sources?
Yes. Permabase Black relies on a non-toxic bio-enzyme catalyst combined with an inert carbon pigment. It contains zero hydrocarbons and zero petroleum-based products. It is 100% safe for use in agricultural perimeters, near livestock, and adjacent to aquifer recharge zones — unlike oil-based emulsions or chemical dust palliatives.
08.Can Permabase Black be used as a chipseal underseal or asphalt prime coat?
Yes. Permabase Black at its standard 10:1 dilution serves as an ideal underseal before chipseal applications — stabilizing and sealing the base course. It also functions as a polymer-based prime coat and tack coat for asphalt overlays, replacing traditional petroleum emulsions with an environmentally safe alternative.
09.What is the CBR improvement from polymer soil stabilization?
Polymer bio-enzyme soil stabilization using Permabase Black can increase California Bearing Ratio (CBR) values by 300% or more compared to untreated soil. The exact improvement depends on soil classification, moisture content, and compaction effort, but the permanent chemical alteration of the clay mineralogy consistently produces dramatic load-bearing improvements.
