Engineered Wood Fiber

An affordable surface solution that meets ASTM guidelines

Created By Nature, Engineered By GT Impax

Engineered Wood Fiber (EWF) is a popular choice for budget-conscious playgrounds. While affordable, Engineered Wood Fiber will require ongoing maintenance and occasional topping off during its lifetime. This maintenance will help uphold the recommended compacted material depth, thus keeping the surface compliant with applicable standards and warranty. 

Newly installed Engineered Wood Fiber settles to form a “knitted” compacted layer that will support a variety of mobility devices. The product is non-toxic and does not contain paint, chemicals or additives.
