Grouting & Pipeline Repair

Our Grouting Division takes on many tasks in the upkeep of our communities’ sewer systems – but their main responsibility is to stop groundwater infiltration. From fixing underground pipe leaks, to pressure-testing, to sealing dilapidated manhole vaults, our team can prolong the life of current sewer and pipe systems for years and years.

If an underground pipe or manhole vault is leaking, it runs the risk of seeping into the groundwater as well as the other way around – our groundwater getting into our sewer systems. Any water coming through our sewers is treated by a Water Treatment Plant – a process that costs the city and taxpayers money. If there’s multiple leaks in the sewer system and the Water Treatment Plant has to treat all the additional groundwater, it can get expensive fast.

Underground Grouting

When underground pipes leak, one option is to dig in the ground and replace the broken section of pipe. The alternative (and much less expensive) method is to call Pro-Vac’s Grouting Division. From above-ground, we can find the exact points of leaking and “spot-repair” the pipe. Our special mixture of grouting compounds are as thin as water and get pumped into the cracks and leaks. Once the compounds are mixed in the soil, it turns the soil into a watertight gel compound that will effectively seal the leaks.

Essentially how it works, is that it patches the pipe from the OUTSIDE. Whether the leak is in a straight pipe, lateral pipe, or a joint – we have the equipment and expertise to bring the pipe back to 100% functionality. The grouting compounds that we use are permanent fixes. They will be the solution to a leak in the sewer system for years and years.

As with all our services, we are very big on maintaining the environment of the communities we work in. The same goes for the chemicals we use in our grouting compounds. Once the compound is mixed in the soil, it is completely inert. No dangerous chemicals are used that might hurt the environment.

Sealing Vaults

In addition to pipeline repair, Pro-Vac’s Grouting Division can also seal dilapidated manhole vaults and other sewer components as well.

The constant churning of our sewer systems produce hydrogen sulfide [H2S] gas. Over time, that gas will erode the concrete of our sewer vaults. Some sewer systems that were built 50 or 60 years ago are in desperate need of upkeep to avoid groundwater leaks. Using our chemical and cementitious techniques, Pro-Vac can effectively bring these vaults back to life.

Starting with a pressure wash, we then apply a thick coat of our compound that is resistant to H2S gas and help protect the concrete underneath. Our compound is designed for use in the humid conditions of a sewer system and as with our underground grouting compound – is completely safe for the environment.

In any repair on our cities’ sewer systems, the main goal is to prevent groundwater leaks. As one of the largest Grouting Division resources in the area, you can rest assured that our team has the knowledge and resources to get your system back to 100% functionality.
