Using Polyacrylamide (PAM) to Reduce Erosion on Construction
PAM does not directly protect soil from rain droplet impacts, but it reduces soil detachment, maintains the soil’s structure, and increases infiltration rates early in the rain event. PAM is applied as a liquid using typical erosion control equipment such as hydroseeders or hydromulchers.
Erosion prevention practices - tackifiers and soil stabilizers
In general, soil stabilizers (also known as soil binders) are used to increase soil adhesion, which improves soil stabilization by reducing water and wind driven erosion. Tackifiers are used as “glue” to bind and immobilize straw, cellulose products, pine needles, or other mulch that has been applied to a seeded area.
G1866 Using Polyacrylamide to Reduce Soil Erosion
Soil erosion due to irrigation can range from none, on many. center-pivot-irrigated fields, to over 30 tons per acre per year on intensely farmed furrow-irrigated fields. High soil erosion rates occur either from furrow-irrigated fields with slopes greater than 3 percent or on soil prone to erosion.

You can also choose from free samples. There are 147 soil stabilizer liquid suppliers, mainly located in Asia. The top supplying countries are China, Turkey, and Malaysia, which supply 87%, 4%, and 2% of soil stabilizer liquid respectively. Soil stabilizer liquid products are most popular in Domestic Market, Southeast Asia, and Mid East.
Salts and Chlorides Remediation - 3 Tier Technologies
Salts and Chlorides Remediation The remediation of salts and chlorides is not a process of consumption but rather a process of binding, buffering, immobilization, detoxification, filtering, or conversion into a non-toxic soil mineral. This is accomplished in a variety of both cationic and anionic processes and reactions.

Polymer soil stabilization - Wikipedia
Soil characteristics that have been altered by addition of polymers include compressive strength, volume stability, hydraulic durability, and conductivity. Polymers can help prevent soil erosion and increase infiltration of water by strengthening soil aggregates and supporting soil structure. The properties of the soil itself are a dominant control on the ability of polymers to interact with it.

Corrosive Soils | Colorado Geological Survey
Corrosive Soil Damage. Corrosion is typically a result of contact with soluble chloride salts found in the soil or water, which requires moisture to form solutions of these salts. Several key factors that influence the severity and rate of corrosion include: the amount of moisture in the soil, the conductivity of the solution, the pH of the solution,...

A small amount (0.5 mg. L-1 or 1 mg. L-1) of poly-aluminum chloride can improve the performance of soil coagulants for the removal of turbidity. The application of soil coagulants didn't introduce coliforms, although the total bacteria number of treated water increased to 40 CFU (soil A) and 81 CFU (soil B), still meeting the drinking water quality standards (<=100 CFU).
