THE BEST SEPTIC TANK RISERS YOUR MONEY CAN BUY!

There are many different types and styles of septic tank risers on the market today. Our 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!
• LIDS WITH HANDLES – The 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 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
