Encasement is the term used to describe the coating over, covering or "encasing" of all building components, interior and exterior. This includes all roofing and toxic hazards materials, such as asbestos, lead-based paint, mold/mildew and other harmful substances, found in buildings. The technique of encasing all building components, including unsafe ones, with green coatings is by far the most efficient way to reduce the harmful effects on people and the environment while lengthening the life of buildings. It also happens to be the economical alternative to other abatement methods, such as removal, disposal and replacement.

Encasement with green coatings is a long term, sustainable and, more importantly, renewable solution compared to typical paints or coatings which only last a few years.

In place management and restoration with encasement green coatings is the best and most practical way to extend a buildings life along with safely dealing with most of its components.

Encasement is defined by the EPA as a, "Spray applied enclosure" abatement method that safely and economically seals and encloses exposed hazardous material surfaces. Encasement differs from encapsulation in that it is a long term solution; the materials are thicker, applied from 7 to 40 mils depending upon surface conditions, building use and desired warranty, are impact resistant and can allow for mechanical fasteners to be adhered to the surface. Materials used for this method should be water-based and must possess elastomeric properties. The outer shell of the encasement is highly resistant to damage from ultra-violet light, heat, water, acids, accidental or direct impact, seismic and mechanical occurrences. This method is installed without disturbing the asbestos fibers and lead dust, requires minimal to no relocation and can be installed after work hours thereby limiting downtime in an organization. Most importantly, GEI's Encasement systems do not affect the fireproof rating of the structure while simplifying in place management monitoring requirements.(GEI)

Pros and Cons of encasement
PROS

•	Installation does not disturb asbestos fibers or lead dust

•	Conforms to safety measures for installers and occupants of dwellings during implementation of corrective actions

•	Lasts for the life of the building

•	Minimal to no relocation of building occupants

•	Can be installed after work hours thereby limiting downtime in an organization

•	Does not affect the fireproof rating of the structure

•	Retains the superior fireproofing qualities of asbestos

•	Prevents lead leachate

•	No need to scarify surfaces, remove walls or trim

•	Non-destructive -- permits preservation of architectural features (wood, plaster, metals, etc.)

•	Excellent protection and preservation

•	Water-based (safe), non-toxic, low VOCs

•	Can be custom tinted

•	Protects surfaces from damage

•	Hazardous waste in place management eliminates hazmat waste transport and disposal

CONS

•	The hazardous materials are safely managed in place, still in the building doing what they were originally intended to do.
