Septic Tank Risers and Lids

Septic tank risers are designed to bring the access of a buried septic tank up to grade for easy access for routine pumping and maintenance. Our Polylok risers and lids are made of high density polyethylene plastic which gives them strength for direct burial and foot traffic, but also makes them lightweight for easy handling during installation and system maintenance.

THE POLYLOK ADVANTAGE

Today's market offers a wide variety of risers for septic tanks, but the Polylok brand risers and lids are unmatched in quality and value. Here are key reasons why:

INTERNAL STRUCTURAL RIBS

The Polylok risers have structural ribs internally around each riser section which give them great strength and allow them to hold their shape with the pressure of soil being pushed against them once the hole is back-filled. These internal structural ribs allow the outside of the riser to be smooth, this is important because of the freezing and thawing of the ground in many areas. When the ground freezes and thaws it expands and contracts and products with structural support on the outside of the riser can actually be lifted from the tank causing damage to the riser and the seal. The Polylok products will have no issues in frost areas because they are completely smooth on the outside!

LOW PROFILE LIDS WITH HANDLES

The septic tank access lid on a riser system is one of the most important components, because it is what you see in your yard and also what you have to remove every time the system is pumped or maintained. The Polylok lids come with pre-installed handles that allow you to easily remove the lid any time you want to access the system. The lids are structurally supported on the bottom which also allows them to be relatively flat, instead of domed shaped like many other products on the market.

LARGE TANK ADAPTER RING

Installing septic tank risers requires an adapter ring, and Polylok offers one of the largest and most versatile adapters on the market. It can cover openings up to 25 inches square or 27 inches round, accommodating both 20-inch and 24-inch risers for maximum flexibility regardless of your opening size.
