HDPE ADJUSTING RINGS - RECYCLING MAKES SENSE!

While basics of the sewer industry have slowly changed over the years, some products have changed dramatically. Today it is possible to eliminate the Achilles heel of your manhole/catch basin structures - the concrete adjusting ring. Utilize the proven strength and durability of concrete precast structures, with our High Density Polyethylene Manhole Adjusting Rings, and eliminate the Achilles heel from invert to rim!

AS A MUNICIPALITY OR THE DESIGNING ENGINEER, WHAT CAN I EXPECT FROM HDPE RINGS?

• Water tight joints, eliminating wastewater treatment costs associated with treating groundwater from infiltration between broken / cracked / deteriorated concrete adjusting rings.
• A mortarless system above the MH cone or top slab. The concern of inconsistent mortar mix from job to job, day to day or even batch to batch is eliminated. Sealing is quickly and easily accomplished with one of several products.
• The settlement of road surfaces around castings and MH rings due to deteriorated mortar and concrete rings, requiring costly rehabilitation projects, will become a concern of the past. Since the rings are not bonded together by mortar, the mortar can not deteriorate, and the migration of fine soils through cracked concrete rings will no longer contribute to road surface breakup.
• Plastic adjusting rings are inert to internal corrosion due to sulfuric acid, created from hydrogen sulfide gases and moisture common to sanitary sewers. The concerns of sulfuric acid attacking adjusting rings over time can now be forgotten.
• HS 25 loading - The HDPE rings are designed and tested to withstand loading in excess of HS 25.
• MnDOT approved - Technical Memorandum No. 96-22-DS-01, dated June 20, 1996 approves the HDPE Adjusting Ring on all state projects.
• Recycling makes sense! Help recycle the post consumer curbside waste within your community. HDPE rings are made of everyday consumer plastic products. Utilize an environmentally friendly product and improve your infrastructure at the same time.
• Two Year Warranty - LadTech, Inc. is so confident in it's product, it warrants the adjusting ring for two years against defect in materials. Will your current adjusting ring supplier warrant their material.

AS THE CONTRACTOR, WHAT CAN I EXPECT FROM HDPE RINGS?

• Ease of installation - HDPE rings are lightweight, (approx. 6 lb. per ring), which help reduce handling and transportation costs. Utilize pickup trucks for transportation instead of larger, more costly equipment.
• Eliminate the mixing of mortar - Reduce your overhead by eliminating your concrete mixer and trailers full of sand, mortar mix, and water. Instead, simply apply an approved sealant between each ring, (check with your local ring distributor for details).
• Reduce jobsite liability since there's no need to wait for mortar to harden, the excavated holes can be filled and compacted as soon as the casting is placed.
• Broken and wasted rings are a concern of past - The distributors of the HDPE Adjusting Rings are authorized to replace any ring which is damaged in any way, due to material defect or handling by the manufacturer, distributor, contractor or municipality. Simply return the ring to your distributor for credit or new rings.
