Lids and Risers
Risers provide access to septic tank openings and can be cast into the tops of concrete tanks or bonded in place using adhesives from Adenus Technologies. Risers are available in sizes ranging from 6 inches to 13 feet in height. Risers are available in 24" and 30" diameters.
Polycarbonate and fiberglass lids are ideal for creating a watertight seal on a tank's access riser. Our lids offer wheel load ratings of up to 8,000 pounds (24" lids only).
Additionally, Adenus offers 24" metal lids that are strong enough to handle vehicular traffic.
