Leak sealing in utility vaults is a critical aspect of maintaining infrastructure integrity. Various methods and materials are available for this purpose, but they are not all equal in terms of performance.

Cementitious Grouts

Cementitious grouts have been a traditional choice for sealing leaks. However, they come with their own set of limitations. Cementitious grouts are rigid and thus prone to cracking over time, especially in the presence of any movement or shifting in the structure.

Polyurethane: Long-term Effectiveness

Material Longevity

One of the standout benefits of polyurethane grout is its longevity. When applied correctly, the material has a lifespan of up to 50 years. This longevity makes polyurethane grout an ideal choice for applications where long-term performance is critical.

Flexibility After Curing

Unlike cementitious grouts, which are rigid and can crack over time, flexible polyurethane grouts remain flexible even after they have cured. This characteristic is essential in structures that may experience slight shifts over time or undergo freeze/thaw cycles. The flexibility of polyurethane grout accommodates these movements, reducing the likelihood of cracks and subsequent leaks.

Polyurethane: Economic Efficiency

The durability of the polyurethane grout means fewer if any, reapplications are needed over time. Additionally, its quick-setting nature often results in reduced labor costs, making it a cost-effective choice in the long run.

Environmental Considerations

The use of polyurethane repair grouts that meet NSF/ANSI/CAN 61 standards is crucial for any project that involves materials coming into contact with drinking water or where environmental safety is a concern. Administered by the National Sanitation Foundation (NSF), an independent certification organization, these standards subject products to rigorous testing and facility inspections. Adhering to these standards is essential for compliance with the Safe Drinking Water Act (SDWA), a U.S. law that sets quality standards for drinking water and imposes penalties for violations. Alchatek's NSF-certified materials meet these stringent public health and safety benchmarks, undergoing regular evaluations, lab tests, and facility audits to maintain certification.

Key Takeaways

• Polyurethane grout excels in terms of material longevity and the flexibility it retains after curing.
• Economically, the long-term cost benefits of using polyurethane grout outweigh the initial higher material costs.

Environmentally, Alchatek’s NSF-certified polyurethane grouts are formulated to have a minimal impact, making them a responsible choice for modern infrastructure maintenance.

Regarding water infiltration in utility vaults, precast joints often serve as weak links. Conventional methods like cementitious grouting offer temporary solutions but often fail to withstand structural movements or shifting over time, resulting in a reoccurrence of leaks.

Repairing Precast Joint Leaks with Spetec PUR GT350

Utility vaults are constructed from precast concrete sections that are joined together. The connections between these concrete sections are called precast joints. Over time, precast joints may develop small gaps caused by things like soil movement or temperature changes. These gaps allow water to leak into the utility vault.

An effective solution is using a combination of Spetec PUR GT350 and Spetec Oakum. Spetec PUR GT350 is a flexible polyurethane grout that can accommodate movements between sections of precast concrete. Spetec Oakum is an oil-free dry jute rope that, when used in conjunction with the grout, helps seal large and irregular-shaped defects.

Installation Steps

1. Clean the surfaces where you plan to apply the Oakum. Moistening the surfaces can enhance the reaction with the resin.
2. Cut the Oakum into appropriate lengths.
3. Saturate the Oakum with Spetec PUR GT380 resin in a clean container, allowing time for the resin to soak in.
4. Using gloves, pull a section of the saturated Oakum through a loose set to remove excess resin.
5. Dip the Oakum in a pail of water to initiate the resin's expansion.
6. Tightly pack the Oakum into the leaking precast joint using an appropriate tool, such as a screwdriver or wooden dowel.
7. If needed, inject additional resin directly through the Oakum via a grout needle or by drilling holes into the concrete behind it.
8. Allow the material to cure overnight before trimming any excess foam.

Repairing Pipe Penetration Leaks with Spetec PUR F400

Pipes for utility lines pass through openings in the walls of utility vaults. These openings are called pipe penetrations. Concrete and/or sealant around the pipe penetrations can break down over time. The vault walls may also shift a little bit. Both of these issues can lead to gaps around the pipe penetrations, allowing water to leak into the vault.

Qualified contractors can use Spetec PUR F400 combined with Spetec Oakum to achieve long-lasting results.

Installation Steps

1. Soak Spetec Oakum in Spetec PUR F400 polyurethane grout, and then quickly submerge it in water.
2. Immediately pack the soaked Oakum around the pipe sitting in the sleeve, allowing it to harden into a tightly sealed gasket.
3. If further sealing is required, use an injection needle to fill the area behind the Oakum with more chemical grout.

The longevity of this approach is remarkable, offering durability that could last up to 50 years.

Key Takeaways

• Polyurethane grouts like Spetec PUR GT350 and Spetec PUR F400 offer superior performance and durability for sealing leaks in utility vaults.
• When used in conjunction with Oakum, these grouts provide effective solutions for addressing leaks at precast joints and pipe penetrations.
• Following the appropriate installation or repair steps ensures that the leak-sealing measures will be long-lasting, potentially offering up to 50 years of durability.
