Installing risers

[wolcottseptic]

Does anyone have any recommendations for whaat type of risers to retofit on concrete tanks. IVe had a couple customers request them and have been turning them down but now id like to get into it. There isnt anyone locally who sells concrete ones so my only option is plastic. DOes anyone make there own concretes, and if so what type of concrete do u use. thanks for any input

I have had good luck with the Polyloc brand risers. They have available an adapter ring which makes it easy to install on the tanks.

As a precaster, we do offer concrete risers but they can be hard to handle and most folks don't want a concrete lid with rebar handles sticking up, especially on a new construction. We also offer a product calles ultra rib that fits down in our 24" round manholes,that can be cut to any length, with a heavy plastic lid secured with srews. For tanks with odd size openings, we offer Poly-Lok adapter rings that are ready for either a 20" or 24" riser rings. Poly-Lok makes there riser rings in 12" and 6" lifts that are easily installed. WE currently sell the 20" which still allows good access. One draw back on concrete or Poly-Lok risers is not being able to cut them to an exact height

The precast tanks in our area have two 21"(?) round concrete lids that are beveled. Black ABS culvert can be easily cut to length with a hand saw, placed in the hole, sealed up with caulking and the original lid put on top and buried a few inches below grade.

Good luck.

Hi All,

For tanks that arnt over 2 feet deep I prefer precast concrete risers, you just can't beat the price or durability. If the tank is deeper than 2 feet we use fralo's tank adapter ring, plastic culvert pipe and fralo's lid. My only gripe is the tank adaper ring is a bit more pricey than I would like.

Our company uses a ribbed 24" smooth inwall pipe that comes in 20' lengths @ about $15 to $18 per foot. We cut it to fit with a saw zaw or circular saw. The lid we purchase from Ball, Bounce and Sport / Hedstrom. The lids come with a seal and screws. They can be filled with sand and the price is very reasonable. You can find the Vendor for them in the Pumper magazine.
When it is installed we pour a bag of quickcrete around the bottom to make it water tight. Just make sure you back fill evenly to keep the riser / manhole from sliding out of place.
