MANHOLE RESTORATION

Multiple options to achieve highest quality results

When it comes to manhole and access structure restoration, today’s complex infrastructure requires multiple options to meet very specific application needs. Our services include the following.

Manhole & Structure Inspections

Many sewer system deficiencies can be identified via good, old-fashioned visual or physical inspection techniques. Our expert technicians can open manholes and other available access structures to inspect and document actual conditions. We also do manhole vacuum testing, a simple process with specialized equipment that enables us to quickly and easily find leaks or verify that repairs were done successfully.

Manhole Grout Injection

Sealing manholes via chemical grout injection involves drilling holes in the general area of leakage and then injecting grout to form a watertight barrier in the soil behind the manhole wall. The drill holes are then plugged with cementitious compounds.

Although chemical grouting is not a structural repair, it’s an effective method of sealing pre-cast manholes that have leaking barrel joints or pipe penetrations.

Manhole Lining & Waterproofing

Mr. Rehab offers a host of manhole lining and waterproofing options, from spray­ applied micro-silica mortars to high performance epoxy-based resins.

Our decades of experience equips us with the expertise to offer the best lining options to meet specific needs. This provides our customers the highest quality results for the least expense – in other words, the best value!

Manhole Frames & Risers

To properly maintain the top parts of manholes and access structures, we offer riser sealants that are specifically designed to seal the adjustment ring and frame area. Such products can withstand freeze/thaw stress that is common within this part of the manhole.

Are your frames worn out or too low from street elevation? No problem! We can also replace frames and covers and install new risers when required.

Matching the ideal option with the specific application allows our customers to achieve the highest quality result for the least expense.
