Foundation waterproofing - What does it do?
Proper foundation waterproofing is essential to protect a building's structural integrity. Without it, water can seep through, leading to moisture accumulation, mold growth, and even structural damage. By applying effective waterproofing techniques, you safeguard the foundation from deterioration caused by prolonged exposure to moisture.
Why Is Foundation Waterproofing So Important?
Water can easily penetrate unprotected foundations, especially when soil becomes saturated due to rain or groundwater. Over time, this moisture leads to several issues. Firstly, it can weaken the concrete, which might cause cracks and eventually impact the overall stability of the structure. Additionally, unchecked water infiltration can lead to mold growth inside basements, negatively affecting air quality and posing health risks to residents.
Foundation waterproofing also prevents hydrostatic pressure, which occurs when water accumulates around the foundation, exerting force against the walls. This pressure can push water through any small cracks or gaps, further damaging the structure. Effective waterproofing methods stop this process, preserving the building’s strength and integrity for years to come.

Another critical aspect is maintaining the energy efficiency of your home. Water infiltration raises humidity levels, which forces HVAC systems to work harder, increasing energy consumption. Keeping the foundation dry not only protects the structure but also helps in reducing energy bills.
Lastly, a properly waterproofed foundation adds value to the property. Potential buyers are more likely to invest in a home with a well-maintained and secure foundation, giving homeowners a significant advantage when selling.
How to properly waterproof foundations?
Properly waterproofing a foundation involves several critical steps. It begins with surface preparation, where the foundation walls are cleaned and inspected for any cracks or damages. These cracks must be filled with hydraulic cement or a similar sealing material to prevent water from finding weak points to penetrate. Once the surface is ready, the first layer of waterproofing material is applied, typically a bituminous membrane or liquid rubber coating, which acts as the primary barrier against water.
Next, adding a drainage system can significantly improve the effectiveness of waterproofing. A perforated pipe is often installed around the perimeter of the foundation to channel water away from the building. This pipe is placed in a trench lined with gravel, allowing excess water to flow freely away from the foundation.
In areas with heavy rainfall or high water tables, an additional waterproofing membrane may be applied for extra protection. Moreover, insulating boards can be placed over the waterproof membrane, providing both thermal insulation and additional protection against physical damage during backfilling. The backfilling process itself should be done carefully, ensuring that the soil does not place excessive pressure on the foundation or the waterproofing layer.
Finally, regular maintenance is essential. Even the best waterproofing systems can degrade over time. Inspecting the foundation regularly and checking for any signs of water infiltration, such as damp walls or mold growth, will help ensure long-term protection.
Is it worth installing a perimeter drain around the foundation footing?
A perimeter drain, also known as a French drain, is an excellent addition to foundation waterproofing, especially in areas prone to heavy rainfall or where groundwater levels are high. This system helps reduce the amount of water that accumulates around the foundation, minimizing the risk of hydrostatic pressure building up against the walls.
The installation of a perimeter drain begins by digging a trench around the foundation footing. A perforated pipe is then laid in this trench, covered with gravel to allow for proper drainage. The idea is to collect water from the surrounding soil and divert it away from the foundation, either to a storm drain or a sump pump system.
The benefits of a perimeter drain include the reduction of water pressure on the foundation walls, which helps prevent cracking and leaks. Additionally, it can lower the risk of basement flooding, as the system efficiently removes excess water before it has a chance to enter the structure.
Although installing a perimeter drain can be a significant investment, it can save homeowners from costly repairs related to water damage. In combination with a well-executed waterproofing system, it provides a robust defense against water infiltration, extending the life of the foundation and preserving the value of the property.
What are the common mistakes made during foundation waterproofing?
One of the most common mistakes in foundation waterproofing is using the wrong materials. Not all waterproofing products are suitable for every type of foundation or soil condition. For example, applying a damp-proofing solution instead of a true waterproofing membrane can lead to insufficient protection, as damp-proofing only prevents moisture vapor from passing through but doesn’t stop liquid water. This can result in long-term issues like leaks and mold growth.
Another frequent error is inadequate surface preparation. Skipping the cleaning and crack-filling process before applying the waterproofing material can compromise the system’s effectiveness. If dirt, dust, or loose debris are left on the foundation walls, the waterproofing membrane may not adhere properly, leaving gaps where water can seep through. Additionally, failing to repair cracks in the concrete before waterproofing allows water to penetrate those weak spots, defeating the purpose of the entire process.
Insufficient drainage is another critical mistake. Even with a quality waterproofing system, without proper drainage, water can still build up around the foundation. Installing a drain system, such as a French drain or sump pump, ensures that water is directed away from the foundation, reducing pressure on the walls and preventing potential leaks.
Lastly, neglecting ongoing maintenance is a common oversight. Waterproofing systems can degrade over time due to natural wear and tear, weather conditions, or shifting soil. Without regular inspections, small issues can go unnoticed and develop into significant problems. Keeping an eye on the condition of the waterproofing system and addressing any issues early on helps to maintain its effectiveness and prolong its lifespan.
PRODUCING THE BULLET JACKET
All our bullet jackets are made from gilding metal, a copper alloy composed of 95% copper and 5% zinc. In order to match our different bullet requirements and meet stringent quality objectives, we buy nineteen different strip sizes of gilding metal and require three times more dimensional and quality control than is considered standard in the copper manufacturing industry. In fact, Olin Brasshas a special alloy exclusive to Sierra Bullets. This enables us to build extremely high uniformity into every one of our finished bullets.
The bullet begins to take shape during the manufacturing process when the jacket material is first blanked and then brought through a series of drawing processes. Special tooling made in our own tool and die shop ensures that the jacket is drawn evenly and that uniform wall thickness is maintained for accuracy. Jackets which have been drawn to the proper wall construction are then trimmed to a length with a tolerance of +/- 0.001.” This ensures consistent weight and proper forming when the bullet is assembled.
After each step, the bullet jackets are washed and rinsed using a special cleaning process developed by our experienced personnel. During each phase of production, roving quality control inspectors check specifications to ensure that the only part to move on is a perfect one. Reports on the quality of parts being manufactured are maintained in every department and are periodically reviewed by shift supervisors.
