When is Interior Building Waterproofing the Better Option

In many cases, interior building waterproofing is the better option for a number of reasons.

One of the main benefits of interior waterproofing is that it is less disruptive to your daily life. Unlike exterior waterproofing, interior waterproofing does not require excavation or heavy machinery, so there is no need to disassemble the veranda or deck during the process.

Interior waterproofing is also more cost-effective than exterior waterproofing in many cases. The process is less complex, and there is no need to deal with the complications that come with exterior excavation and heavy machinery. This can save you money in the long run and provide you with peace of mind knowing that your home or building is protected from water damage.

Another benefit of interior waterproofing is that it can also help to improve indoor air quality. The waterproofing system helps to prevent moisture from entering the building, which can reduce the risk of mold and mildew growth. This is especially important for those who suffer from allergies or respiratory issues.

Finally, interior waterproofing is a great option for those who are looking to increase the value of their property. A waterproofed building is less likely to suffer from water damage, which can be a significant selling point when it comes to selling your property in the future.

At Flood Tech, we have the experience and expertise to help you determine whether interior waterproofing is the right choice for your home or building. Our team of professionals will conduct a thorough assessment of your property and provide you with a step-by-step plan for protecting your investment from water damage.

Inaccessible Exterior Walls

If there is not enough working space on the exterior of the house to properly dig and install a waterproofing system.

Hydrostatic Pressure Issues

When facing hydrostatic Pressure issues, water is coming from below the footing and must be redirected from the inside.

Unfinished Basement Access

When a basement is not finished, the economical solution is to do interior waterproofing.

How Interior Waterproofing Works

Similar to external waterproofing methods, the primary goal is to capture and redirect the water using these methods:

  1. Rubberized Membrane: A special rubberized membrane is applied to protect against water infiltration and condensation.
  2. Drainage Membrane: An air-gap drainage membrane is applied to the wall redirecting water safely to the base.
  3. Drainage Tile / Weeping Tile: A drainage tile (weeping tile) is installed surrounding the footing which captures and redirects water to a single location.
  4. Sump Pit: Redirected water is collected in a sump pit that houses an active sump pump.
  5. Sump Pump: The sump pump moves the water back out of the property through a discharge pipe.
  6. Discharge Pipe: On the outside, the discharge pipe releases the water away from the property foundation. 

This complete waterproofing system controls every type of water entry and creates a foolproof water barrier ensuring your property remains dry and safe from water damage.

How drainage systems work

Interior basement water drainage systems work by redirecting water away from the basement and safely out of the building. This is achieved through a combination of materials and processes that are designed to prevent water from entering the basement and to remove any water that does enter.

The first step in the process is to install a waterproof membrane on the interior of the basement foundation walls. This membrane acts as a barrier to keep water out and prevent it from penetrating the walls.

Once the membrane is in place, the next step is to install a drainage system. This typically involves installing a perforated weeping tile pipe along the footer of the basement, which is designed to collect and divert water away from the building. The pipe is surrounded by a layer of crushed stone or gravel, which helps to increase its effectiveness by promoting rapid water drainage.

In addition to the weeping tile drainage system, a basin and sump pump is also installed in the basement. This is a pump that is designed to automatically remove water from the basin and direct it out of the building. The sump pump is connected to the drainage system and is controlled by a float switch, which triggers the pump to turn on and remove water as soon as it reaches a certain level. This ensures that the basement remains dry and protected from water damage.
