Estimating The Cost Of Waterproofing A Basement



by Dennis Paker


When figuring the cost of waterproofing a basement, you need to start by evaluating the condition of the foundation, walls, and flooring. It costs quite a bit less to fix minor, internal problems when they are first discovered than allowing them to grow into larger issues. Depending on what you find, there are several reasons and factors to consider before moving forward with repairs.

Aging homes begin to produce leaks. Underground basements are prone to leaks over the years. Thankfully, as time passes, the standards used in new home building continues to improve. Legal codes and contractor practices have made protecting the foundation a priority to ensure it lasts for many years.

Leaks and water damage happen for several different reasons. The pressure that is applied by outside forces, such as the earth settling, can be part of the cause. Trees that are planted close enough may grow roots towards and under the foundation. Erosion is also known to shift the landscaping to provide a direct path towards the house.

Internal cracks and leaks are easy to fix. These often appear due to slight shifts and settling. When they occur, they may develop mildew. There are several products available that can be used to fill and seal these cracks to prevent water from seeping into the house. Often, this can be handled without the assistance of a professional. However, if the cracks continue to grow, separate, or begin leaking pools of water, you will want to have them looked at by a specialist.

Repairs to the external foundation can be expensive. If the external damage is significant, the contractor often has to dig a trench next to the house. This will give them a better idea of what exactly is happening to cause the severe leak. With this type of a job, you may want to discuss preventive measures that can be put in place while the foundation is exposed.

Proper landscaping can prevent future problems. Trees growing too close to the house can present a problem when the root systems begin to branch out. The slope of the ground should encourage water to drain away from the house. Finally, there should be good ground cover to prevent erosion. Exposed dirt can easily flow away in a large rainstorm.

Installed draining pipes help siphon the water from the foundation. A rubber membrane can also be installed to help provide a much better seal. The drainpipe should be perforated and covered in gravel with sand on top. This helps provide a better way for the water to find the exit. Lastly, the pipe should extend beyond the end of the foundation.

As you begin the process of calculating the cost of waterproofing a basement, remember to start with the evaluation. If the carpet has wet spots, pull it back to look for cracks or seepage. Check the outside wall for damage in areas that seem to be causing problems. Repairing the problems when they are relatively minor will be much less expensive than allowing them to grow until they produce a disaster.
