BENEFITS OF ADDING SEPTIC TANK RISERS

Convenience: Eliminates the need to dig up soil to access the tank, saving time and labor during maintenance.
Cost Savings: Reduces labor costs for septic professionals, as they don’t need to spend time excavating.
Safety: Prevents accidental damage to the tank or surrounding landscaping during digging.
Aesthetics: Risers can be capped with discreet, flush-to-ground lids that blend with the landscape.
Longevity: Modern materials like high-density polyethylene are durable, resistant to corrosion, and can last for decades.

THE INSTALLATION PROCESS

The installation of septic tank risers can be done by a DIY homeowner or a septic professional. Below is summary of what you should expect during the installation process:

Locate the Tank: Find the septic tank’s access lid(s), usually buried 6" to 36" below ground
Excavate: Dig carefully around the lid to expose the tank’s access port
Attach Riser: Secure the riser to the tank opening using an adapter ring or sealant (e.g., butyl rubber or silicone caulk) to ensure a watertight fit
Stack Risers: Add riser sections to reach ground level or slightly above.
Secure Lid: Install the cover with the included hardware
Backfill: Refill the area around the riser with soil, ensuring stability and proper drainage

THE POLYLOK SEPTIC TANK RISER SYSTEM ADVANTAGE

There are many different types and styles of septic tank risers on the market today. The Polylok septic tank risers are simply the best your money can buy. The reasons are many, but here are the most important:

INTERNAL STRUCTURAL RIBS

The Polylok septic tank 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 backfilled. 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 RISER 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 standard 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

In order to put septic tank risers onto your septic tank, you need an adapter ring. Polylok has one of the largest adapter rings on the market allowing you to cover up to a 25’’ square opening or a 27’’ round opening. This ring accepts both 20’’ and 24’’ risers and gives you great flexibility no matter what size your opening may be.
