Risers / Grade Rings
Shoaf Precast offers different size concrete risers available in either round or square shaped depending on your preference and/or need. Considering the location and vehicular traffic that the riser may be exposed to, we have H/20 (traffic rated) or non-traffic concrete risers in which are edged and finished to create an appeasing curbside like finish. If you prefer an easy and lightweight solution, we also offer
EZset and Polylok plastic round risers (non-traffic). Risers are very beneficial as they allow for easy location, inspection and pumping of your tank.
Our experts would be happy to help you with your custom needs and specifications as well. Given a reasonable time of notice, we can custom make risers/underground utility boxes to accommodate duplex, triplex and quadplex pump stations with large 4' X 4' aluminum hatch openings. Please give us a call today!
