Acrylic waterproofing coating is a water based, seamless elastomeric coating manufactured from pure acrylic polymer. It is a single pack material that bond to roofs and walls, and provide a thick flexible membrane that is totally waterproof and weatherproof.

Activated carbon is made by heating organic matter such as wood, coal, and lignite, to leave a carbon residue, which is then activated by partial oxidation with carbon dioxide, steam, or oxygen in air. It comes in the forms of granular activated carbon and powdered activated carbon. It is a widely used sorbent applied to the removal of organic vapors from air, organic solutes from water, and to a certain extent, inorganic solutes from water. It is used for several purposes in waste treatment.

Activated carbon filters work by absorbing contaminants onto the surface of carbon particles. They can improve the taste and odor of water by removing certain industrial wastes, pesticides, decaying organic material, dissolved gases, residual chlorine and by-products of chlorination. Activated carbon effectively removes many chemicals and gases, and in some cases it can be effective against microorganisms. However, generally it will affect total dissolved solids, hardness, or heavy metals. Activated carbon is created from a variety of carbon-based materials in a high-temperature process that creates a matrix of millions of microscopic pores and crevices. It is used to remove certain microorganisms and certain organic chemicals, especially pesticides, THMs, trichloroethylene and PCBs.
