Production and application of fire resistant erosion control mat

Abstract

A fire resistant ground erosion control mat assembly. The mat assembly includes an inner layer of fire resistant milled stone mineral wool material with an upper and a lower layer of supportive nets. Each of the upper and lower nets consist of fire resistant milled mineral foraminous nettings to enable passage of light and water therethrough as a ground positioned emplacement of the inner layer.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a construction of a fiber matrix utilized for the protection of surface soils, subsurface soils, turf and vegetation typically disturbed by construction activities or eroded by the forces of falling and flowing water. Such fiber matrix may be identified as a permanent Rolled Erosion Control Product (RECP), termed a Turf Reinforcement Mat (TRM), which mat is utilized in conjunction with the vegetation to form a permanent, systemic installation that reinforces that vegetation, improving the overall resistance to nature's hydraulic forces and is a Divisional Application of and based upon U.S. application Ser.

AI Technical Summary

Benefits of technology

The patent describes a way to make a fiber matrix that can be used as a layer of protection against fire and ground erosion. This can be done by using adhesive, resin, or heat treatment to stick the fibers together. Additionally, the patent also describes the use of upper and lower layers of fire-resistant or synthetic nets to provide further protection. The technical effect of this patent is to provide a flexible, effective barrier against fire and ground erosion in construction materials.

Problems solved by technology

However, in many cases, the accelerated or concentrated flow or steepened slopes caused by human development increases the forces of erosion, leaving the vegetation unstable.

Uncontrolled erosion has an enormous impact on our environment, our water sources and on its maintenance and supply for agriculture resources and or maintenance and support of wildlife.

Such effects have cost billions of dollars each year trying to manage or correct for those deleterious effects.

Channels and waterways become filed with sediment, shorelines may be lost, and fertilizers may collect in water supplies to poison such water.

However, melt bonded products lack the inherent strength the netting provides.

As such, biodegradable or otherwise degradable components may not be utilized in the fabrication of TRM.

One significant problem with the prior art is the potential for ignition when the ground cover mat is exposed to heat or flame.

The families of synthetic materials utilized for TRMs are not fire resistant.

Chemical additives can improve the ignition resistance, however, such additives typically reduce the product's lifespan when exposed to sunlight.

Even the few technologies that offer flame and ignition resistance and are UV stable offer little true resistance, in practical terms.

When installed in roadside channels or on roadside slopes, particularly in arid climates, extreme temperatures, drought and plentiful ignition sources are cause for concern.

Additionally, placement near important structures is dangerous, as the TRM adds a close-proximity fuel source, in the event of a wildfire, structure fire or other fire.
