“I found installing the Polymer headwalls to be quick and very easy compared to casting headwalls insitu or using PCC headwall units. A huge benefit was the Polymer headwalls are designed to receive flapvalves without any need for drilling into concrete, using expensive epoxy resins or making good around the pipes. The flapvalves provided by Permashutter were simple to install and should require less maintenance than some ductile iron varieties.”Mark Flynn (Barton Civils Project Manager)
