Types of Flexamat
A double layered underlayment system, that includes, in order from top to bottom, a 5-Pick Leno Weave and an Aspen Wood Excelsior Blanket, Curlex II. (view more information about Curlex Blankets) This underlayment encourage vegetation growth and is biodegradable. The Standard Underlayment is designed for climates and applications where vegetation growth is sustained year-round.
The 5-Pick Leno Weave locks the underlayment fibers under the Concrete Block Mat under extreme flow and wave conditions that surpass the capabilities of erosion blankets. The Curlex wood excelsior underlayment layer is specifically designed to promote vegetation establishment. Curlex has a built-in swell factor, where the wood excelsior fibers expand in thickness and interlock to form a strong, fiber matrix, while simultaneously retaining moisture to promote ideal growing conditions.
A triple layered underlayment system, that includes, in order from top to bottom, a 5-Pick Leno Weave, Recyclex TRM (view more information about Recyclex TRM), and a bottom layer of Curlex II Wood Excelsior. This underlayment is used when sustainable vegetation growth in not possible. Examples include semi arid environments, areas susceptible to drought, areas with poor soils, and heavily shaded areas. This product is made from recycled soda bottles (nylon fiber that will not float). This underlayment allows vegetation growth and will remain permanently as an underlayment if growth is not present.
The Concrete Block Mat is manufactured with the concrete blocks cast onto a 10oz. non-woven geotextile underlayment that is adhered to the back of each block. This backing is used in arid areas or in applications where growth is not desired. Flexamat 10NW also used when Flexamat® is installed over plastic liners. The fabric provides a protective barrier between the liner and the concrete blocks. Project requirements determine the fabric used, Flexamat can be manufactured with a wide range of non-woven fabrics.
Flexamat may also be manufactured without underlayment backing, consisting of just the concrete blocks and the interlocking Geogrid. This option is available for projects that require unique underlayment or instances where Flexamat is installed over existing turf.
Interlocking Geogrid Option
Fornit 30-30-35 polypropylene bi-axial geogrid - used in all Flexamat products unless specifically noted. The bi-axial gregrid has a tensile strength of 2055lbs and is UV stabilized. This geogrid was selected after years of research and field testing. Polypropylene geogrid is not adversely affected by the high pH environment encountered when embedding the grid within wet concrete. (Polyester yarns degrade when exposed to uncured, wet concrete having a pH of approximately 11.5.)
Bi-axial Polypropylene geogrid with a high ultra-violet resistant synthetic rubber blend coating with a tan color (for identification). This material is used on Flexamat® projects in arid, desert climates or areas where vegetation growth is not possible or not desired in applications where the mat will not be infilled.
Flame Resistant Geogrid - a bi-axial geogrid with flame-resistant coating. This material is used on Flexamat projects in areas where wildfires or controlled prairie burns are anticipated.
Flexamat can be manufactured with cores within the rolls. A variety of custom core options are available.
