Basement

If you think your basement has water ingress, or issues with moisture it could be caused by defects in the concrete. The most efficient repair is often done by repairing the concrete from the interior. A localized repair done from the interior can be done during any season or weather. 

While repairing concrete, you want to ensure that the work is not going to trap water  and cause high levels of moisture. Crystalline waterproofing or hydraulic cement are often used as they are readily available to the public. These products  tend to trap water within the substrate, and cannot resist cracking due to minor movement. Urethane materials can make a great temporary water stop, however can shrink over time allowing your leak to return. It is critical to ensure a permanent solution is performed when interior finishes may be affected. Drywall and insulation can hide a leak, and they can also hide a bad repair, so make sure you hire someone offering a permanent solution.

Sometimes drainage and waterproofing are so poor that a localized repair to the concrete will not suffice. In these cases excavating the exterior followed by re-waterproofing is required. Waterproofing applications must be done during dry weather, to allow for the material to bond properly.

If you suspect a leak within your basement but cannot tell for sure, it is best to remove a section of drywall to inspect the concrete (or have a qualified contractor do it for you). Cracks and construction joints are the most common source of leaking. If you find a crack or joint, continue removing drywall until there is a clear beginning and end, this will likely be the extent of our repair work.

Sometimes moisture trapped in a wall makes it hard to determine the source right away. Allow trapped moisture to dry, then follow the path of new moisture as it occurs. To speed up this process, a flood test can be done by running a hose at the exterior. This should be avoided if possible, as to not flood the area any more than necessary. If performing a flood test, monitor the interior closely and have someone ready to turn the water off quickly.

At Miller & Co we are also able to install carbon fiber reinforcement to your concrete or masonry block walls to address structural issues. Concrete cracks repairs may include carbon fiber stitches as part of our scope to prevent cracks from opening wider, due to minor settling. If you think additional reinforcing may be required on your project let us know. We provide complimentary estimates and upon request can install a crack gauge to monitor and record any movement occurring to your structure. Once movement is identified we can come up with a solution to improve external reinforcing using carbon fiber.
