Engineer Information
-
Water-Tight Joints, eliminating wastewater treatment costs associated with treating groundwater from infiltration between broken / cracked / deteriorated concrete adjusting rings.
-
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 the 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 LADTECH® HDPE Adjusting Rings are designed and tested to withstand loading in excess of HS-25.
-
Recycling makes sense! Help recycle the post consumer curbside waste within your community. LADTECH® HDPE Adjusting Rings are made of everyday consumer plastic products. Utilize an environmentally friendly product and improve your infrastructure at the same time.

Contractor Information
-
Ease of installation - LADTECH® HDPE Adjusting Rings are lightweight, which reduces 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).
-
Road Surface - 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 the cracked concrete rings will no longer contribute to road surface breakup.
-
Labor Efficiency - Reduce time spent on jobsites with the HDPE and Butyl system. There is no need to wait for mortar to harden between heavy concrete rings. With Ladtech’s system the rings can be precisely measured, adhered in place, and immediately topped with casting. Then you can simply backfill, tamp then hot/cold patch or pave immediately.
-
Broken and Wasted Rings are a Concern of the Past - Concrete manhole adjusting rings are prone to arriving at job sites cracked or broken, which can lead to groundwater infiltrating your sewer system and causing expensive repairs down the line. LadTech offers a superior solution with its HDPE manhole adjusting rings. These rings are specifically engineered to withstand harsh environments and impacts, ensuring long-lasting performance. Plus, in the rare event that you receive a damaged ring, LadTech guarantees a free replacement at no additional cost. Protect your sewer system and avoid costly repairs with Ladtech’s reliable, durable HDPE rings.
