What could you do wiith 1/4 inch thick seamless material strong as concrete yet flexible as a tire, that can be applied to conform to any shape?

Directly over compacted soil

Structurally Solid & Seamless


The DOT study, and Cal trans use for a decade have proven that asphalt composite vegetation barrier as created by EnviroWeld equipment has eliminated the use of herbicides and long term maintenance of vegetation growth under guardrails 


The gray seamless composite works very simply by eliminating water, air, and adding heat sufficient to stop growth of even the most robust runner based weeds.  EnviroWeld has wored where concrete has failed, and mats have allowed erosion.  The barrier can also be used at the base of fences to create a complete bottom barrier against erosion and digging by small animals.  


Dig out... compact the soil

Apply Direct... Nothing Else Needed


Water is unforgiving of any error.  A ten penny nail hole can leak over 400 gallons every 24 hours under just an inch of pressure.  Water is also heavy exerting over 1000 lbs per sq ft in depths of 20  feet.


Nothing is more reliable or easy to inspect than seamless asphalt composite construction.  Nothing is hidden, and the surface is easy to inspect. The composite has the strength needed and the smooth surface that makes clean out easy.    


Concrete cracks from heat and moisture. 

Confine space... eliminate water.. disperse heat... and functions long term.


Moisture causes rebar to expand from chemical reactions "spall" which requires moisture to occur.  Spall creates internal pressure that causes fracturing.  Seamless asphalt composite holds the concrete together, to act like "confined" concrete, and waterproofing stops the cause of fracturing.

This concrete building was saved from demolition with seamless composite able to confine the concrete.  Confined space forces the fractured pieces together, much like sand can be made to take load if it is held under seamless exterior pressure.  Loose it crumbles, held tight it can withstand pressure.
