Dirty water and mud washing into the streets – these are a few things on construction sites that pose such a nuisance and, at the same time, such a difficult challenge to control. However, ignoring it is simply not an option.
Today’s contractors and engineers are faced with stringent EPA water quality discharge requirements, including NPDES Phase I and II regulations and increased enforcement on job sites. Curlex SiltTRAP was developed to help meet regulatory compliance standards by filtering out sediment from runoff water before it enters storm drains in construction areas.
In addition to the compliance requirements, new residential and commercial developments can enhance the appearance of their projects, while solving problems of soil loss and water runoff by using Curlex SiltTRAP. Since these developments are designed to attract buyers or tenants while under construction, it’s vital to the owners to employ an aesthetically pleasing approach to their projects. The green color gives the appearance of instant natural turf, masking its real purpose of providing erosion control for soil loss and water flow control.
Material Characteristics
SiltTRAP offers a unique way of installing a temporary buffer strip to capture sediment before it washes away, filling gutters, clogging pipes, and generally creating a mess. The naturally seed free, unique Curlex® excelsior fibers in SiltTRAP filter soil from the runoff and greatly reduce off-site problems without the installation and disposal hassles of silt fence. All components of SiltTRAP are degradable, thus there is no need to remove the product after the construction phase is complete.
Curlex SiltTRAP with its QuickGRASS® (green pigment) fibers provides a tremendous visible benefit that is seen the moment it is installed. This is well received in residential and commercial areas where you want to promote a finished effect when your visitors are entering or leaving the site.
Curlex SiltTRAP fibers expand when wet creating a ”clinging” effect to the soil, making the blanket become twice as thick, thereby adding additional protection during heavy rain. The same fibers then slowly release the absorbed moisture back to the soil creating a hygroscopic action that nurtures seeds and promotes revegetation.

Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits.
