R.E.L.L. Corporation is a manufacturer of steel Manhole Risers, Grate Risers, Valve & Sewer Clean-out Risers. We also stock cast Water Valve Risers and Concrete Valve Box Protective Pads (24" square & 24" round).

Manhole Risers are a time and cost effective method of raising a manhole utility cover to a new grade, when resurfacing a road or highway with a new layer of asphalt. The alternative method of raising a manhole involves breaking the asphalt+base, breaking the brick under the casting and raising the whole structure. This typically involves a backhoe & 2 men to complete this task and they may only get 2 or 3 utilities raised a day. Installing a R.E.L.L. Manhole Riser can be done and preferred just ahead of the Asphalt Paving Machine at a rate of 5 minutes a utility. Just think of the daily production possibilities. After the Manhole is securely installed, the Paving Machine seals it in with the new Hot asphalt and minutes later is traffic ready.

R.E.L.L. Manhole Risers are constructed of A-36 Hot Roll steel & Galvaneeled metal and has a stainless steel adjustment stud for diameter flexibility. Each Manhole Riser is coated with a industrial primer finish for extra corrosion protection-std. An optional 2 part epoxy coating is available at an extra charge.

Because R.E.L.L. Corporation focuses exclusively on Manhole Riser construction, we believe our service is second to none in the industry.

So when you need to order Risers for that upcoming overlay job, give R.E.L.L. Corporation a call and see what you have been missing.
