Pipe penetration sealing is a critical aspect of waterproofing in new construction, addressing the potential leaks that occur where pipes and conduits penetrate walls and floors. These penetration points are often the weakest links in a building's defense against water intrusion, particularly in areas subjected to high moisture or water pressure.

Sealing Pipe Penetrations

One of the significant challenges in new construction is ensuring the watertight sealing of pipe penetrations. If not sealed properly, pipes can allow water to seep into the building, leading to electrical hazards and structural damage. The solution lies in using polyurethane grouts, which provide a durable and flexible seal that accommodates the slight movements of pipes while maintaining their integrity against water penetration.

Sealing Electrical Conduits

Electrical conduits require particular attention when sealing penetrations, as water intrusion can lead to dangerous electrical issues. Conduits must be sealed to prevent seepage into the building, while still allowing for slight conduit movements over time. Polyurethane grouts once again provide an ideal solution, forming a resilient barrier against water entry while flexing as needed to accommodate the conduit. This ensures a safe and reliable seal that contains no water penetration risks.

Sealing Pipe and Conduit Penetrations with Oakum

Oakum plays a crucial role in pipe penetration sealing due to its strength and absorbent properties. When soaked in polyurethane grout and then activated with water, it expands, filling gaps and creating an initial seal. Case studies in critical infrastructure, like dams and commercial buildings have shown that the use of oakum in conjunction with polyurethane grout effectively prevents water intrusion around pipe penetrations, even in high-pressure scenarios.

The Pipe and Conduit Penetration Sealing Process

1. Soak the oakum in chemical grout, and then quickly dip it in water. 
2. Immediately pack the oakum around the pipe that is sitting in the sleeve.  It will polymerize in minutes and become a tightly sealed gasket.
3. If needed, use an injection needle to pressure inject area behind the oakum with chemical grout.

Sealing Pipe and Conduit Penetrations

Pipe penetration sealing with polyurethane grout and oakum is a highly effective method in new construction and remedial waterproofing. It addresses the specific challenges associated with pipe and conduit penetrations, offering a robust solution that outperforms traditional sealing methods. This method ensures a safe and dry environment, safeguarding the structural integrity and longevity of new constructions.

Curtain grouting is primarily employed to address multiple leaks at once. This technique originated in the 1960s. It was initially used to remedy water intrusion issues in sewer systems. Over time, its application expanded to a wide range of structures, driven by its efficacy in creating a barrier against water penetration. Curtain grouting involves injecting an expansive polyurethane grout through a wall or floor, into the soil on the other side. The grout then spreads out and expands, forming a 'curtain' that seals many leaks and cracks at once.

A Brief Overview of the Curtain Grouting Process

1. Drill injection holes in a diamond grid pattern.
2. Begin grout injection at the bottom of the wall.
3. Inject grout a little higher, so that any excess grout flows down over the previous injection area. This creates a lapping effect, like shingles on a roof.
4. Continue injection to the top of the wall.

Managing Multiple Leaks

Curtain grouting is particularly valuable in scenarios where multiple leaks are present or when the source of water intrusion is indeterminate. This method provides a comprehensive solution, sealing numerous potential entry points for water and thus is more efficient and cost-effective than attempting to address multiple leaks individually.

Hypothetical Examples

One notable application could involve an existing multi-story building with an underground parking garage, which has water intrusion issues. In another hypothetical example, a new modern high-rise building with below-grade levels planned could utilize curtain grouting during construction, resolving waterproofing concerns without needing extensive excavation or costly, long-term dewatering.

Curtain Grouting in a Nutshell

Curtain grouting is a technique that involves injecting an expansive polyurethane grout through a wall or floor and into the soil behind it. As the grout spreads out and hardens, it forms a "curtain" that seals multiple leaks and cracks at once. This barrier can prevent water from intruding into a structure that has existing issues or be installed proactively in new construction to waterproof below-grade spaces like underground garages. Curtain grouting is often a more efficient and cost-effective solution compared to addressing multiple leaks individually.

Water's destructive capacity stems from its ability to penetrate and alter the very materials that buildings are made of. Here are some key ways in which water inflicts damage:

• Freeze/Thaw Cycles: In colder climates, water that has seeped into cracks can freeze. As water freezes, it expands, widening these cracks. When it thaws, it contracts, leaving space for more water to enter. This cycle of freezing and thawing can progressively worsen cracks, leading to significant structural damage over time.
  
  
• Corrosion: Water is a major catalyst for corrosion, especially in structures with steel reinforcements. When water and oxygen interact with steel, it leads to rust formation. This rust not only weakens the steel itself but can also cause it to expand, affecting the surrounding concrete.
  
  
• Concrete Deterioration: Concrete, though sturdy, is porous. Continuous exposure to water can lead to a chemical reaction known as carbonation, lowering the pH of the concrete and weakening its structural integrity. Moreover, water can carry harmful salts and chemicals that further deteriorate concrete. This is compounded when the structure is on the coast and in a high chloride environment. Over 1/3 of the US population lives in coastal counties.
  
  
• Wood Rot and Mold Growth: In buildings with wooden elements, prolonged exposure to moisture can lead to wood rot, compromising structural strength. Additionally, damp environments are breeding grounds for mold and mildew, posing health risks and further degrading building materials.
  
  
• Damage to Electrical and Utility Systems: Water infiltration in areas housing electrical systems can lead to short circuits, increasing the risk of fire. Similarly, utility systems, such as heating and plumbing, can also be compromised, leading to costly repairs and potential safety hazards.
