Primeline Products Manhole Joint Sealing


As a leading trenchless rehabilitation equipment provider, PrimeLine Products takes pride in offering a broad range of top-quality equipment and related accessories. Our commitment to quality extends to our joint sealing and manhole sealing products.

Here’s a look at our manhole and joint sealing product line:


These chemical grouting supplies are designed to stop groundwater infiltration around pipe joints and manholes. The main feature of all of these products is the proven ability to keep water from going where it’s not supposed to go.

Many of our chemical grouting products have impressive features that include low toxicity levels and optimal durability and strength. We also carry joint sealing and manhole sealing products that are environmentally friendly and expandable to allow for the creation of stronger seals.


All our joint and manhole sealing products offer unique specifications. Avanti chemical grouting products, for instance, can be used to stop active water leaks. Other uniquely appealing specializations of these products include the ability to expand beyond the liquid volume, being non-dilutable in water, and having a controlled reaction time.


Enhanced soil stabilization is one of the many benefits of using reliable joint and manhole sealing products. Being able to prevent groundwater infiltration also makes it easier to complete trenchless rehabilitation projects without the hassle of dealing with excess water that can affect adhesion.

Whether you need crack injection materials or other types of sealants, these products are useful because they increase your ability to deliver the desired results. You’ll also be able to create long-lasting seals in a way that’s efficient and cost-effective.

Here are our featured joint/manhole sealing products:

  • AC-400® – An Avanti chemical grouting product for managing infiltration in sewer joints. It can also be used for the same purpose for curtain grouting and tunneling tasks.
  • DenePlug – Rapid curing, this hydro-active Portland cement quickly cuts off manhole leaks and seals cracks. It can be applied on masonry or concrete surfaces above or below water tables.
  • HYDRO ACTIVE® Combi Grout – Include this expandable material among your chemical grouting supplies and you’ll be able to fill open vent holes with convenient injection packers.
  • HYDRO ACTIVE® Cut – An accelerator that helps grout cure quickly, this sealing material is best for applications involving tunneling, soil or gravel that needs to be stabilized, or the closing of larger volume leaks.
  • HYDRO ACTIVE® Flex 1000 – Ideal for wide cracks in horizontal structures, is resistant to weathering. It also expands according to temperature.
  • HYDRO ACTIVE® Flex LV – An expandable type of chemical grouting, this hydrophobic polyurethane cures quickly. It also creates tight seals in moving cracks.
  • HYDRO ACTIVE® Flex SLV – An ultra-low viscosity hydrophobic polyurethane, this injectable product targets hairline cracks in concrete surfaces.
