To meet the needs of the growing pervious concrete market, add a cross-compacting roller and grooving roller to the Wildcat Roller Screed to make a complete package for placing pervious concrete. This screed is powered by a GX35 Honda engine. The roller screed tubes are offered in 4- to 24-ft. lengths. This form-to-form screed also will produce flat floors with minimal time and labor involved. JLin Corp. 877-220-6652. www.multivibe.com.
