We also supply recycled rubber products for sewer maintenance applications involving general repair, paving and overlay projects. Our product line addresses several important aspects of manhole adjustment from the top down as well as from the bottom up.

| The Easy Riser is an excellent alternative to steel riser rings, or "paving rings," when adjusting manholes to grade. Available in 1", 1.5" and 2" thicknesses, the Easy Riser can be used to adjust manholes with lid diameters up to 26", which alleviates the need for multi diameter "custom" steel risers. Other benefits include: fast, simple installation mere minutes prior to paving; service life equal to surrounding asphalt (can be recycled again with the asphalt!); Easy Bond adhesive creates water resistant seal to existing surface road; reduces stormwater Inflow and Infiltration (silt too); reduces impact damage to manhole / valve stack, extending the life of the structure and the roadway above.

| The Infra-Riser and Flex-O-Ring is a multipurpose rubber adjustment ring for manholes, catch-basins and storm drains. Utilizing these rubber adjustment risers addresses three important issues in Wastewater Management:
- Installation - lightweight with the taper built into the ring allows quick, precise adjustment.
- Infiltration - a polyeurethane sealant bonds to the rubber, concrete and the cast-iron forming a water tight seal.
- Impact - disperses weight evenly, extending the life of the structure and the pavement.
|
| Rubber adjustment risers are available in many configurations: circular, square and rectangular:
- Flat rings are 1/2", 1", 1.5", 2", 2.5", 3".
- 1/4 inch flat rings available.
- Tapered rings range from 1/2"to 3" in 1/2" increments.

The Infra-Riser and Flex-O-Ring are designed for use on the final few inches when adjusting manholes and catch basins to grade. Various thicknesses flat & tapered simplify the process and alleviate the need for shimming. This produces a more precise adjustment, faster, and is longer lasting. These grade rings are used singly or together, with and without concrete "donuts." These manhole adjustment rings also act as gaskets in that they form a water tight seal at this crucial joint, preventing inflitration; A polyurethane sealant is used which bonds to the rubber, concrete, brick & mortar and the manhole. Removal of "point loading" combined with load bearing capacity extends the life of the structure as well as the surface above.
