It’s surprising how quickly a bad situation can get worse. This is so true when you have a basement that has  Quickly getting wet basements dry is very important to avoid dangerous mold and mildew.

How We Can Waterproof Your Basement.

Basements become damp or flood due to a number of causes. Our fist step is to identifying what is causing your problem. Every situation is different but at the same time fairly straight forward to correct. We can repair cracked foundation walls and floors. We can seal cracks with epoxy injection and also apply other waterproofing products to get your basement water tight. Water can enter your basement or crawl space from cracks in the floor and walls. Water can also seep in along the joint between the floor and the walls. Sometimes basements flood due to window wells or walkout egress entrances.

Crack Repair with Epoxy Injection

An effective method to repair cracked basement walls and floors is epoxy injection. As the name suggest we will will the cracks with a specialized epoxy that is injected into the cracks and will seal them tight. For more information visit our epoxy injection page.

Basement Drainage System Installation and Repair

If your home was built within the last 40 years chances are you already have a drainage system around the perimeter of the foundation walls. Your home may have drainage tiles or pipe installed under your concrete slab adjacent to the walls. This type of drainage system is usually connected to a sump pit and pump. Sometimes the drainage system can become clogged. If this is the case we should be able to flush the drainage system and remove any clogs. This is of course considering if the system was originally installed correctly and has no other damage besides a clog.

When there is not a drainage system in place or the system needs to be replace we can install a new drainage system. When installing an interior drainage system we will need to use a heavy duty concrete saw and cut out enough concrete so that we can install a new French drainage system. Once the concrete is removed we will need to dig to the appropriate depth so that we can fill the trench with gravel and the perforated drain pipe. Drain pipes should be covered with a specialized cover called a sock that will help keep debris from entering the perforated holes on the pipe and prevent future clogs. We will also want to design the system with at least one clean out points for easy access for clean out and observation purposes.

Sump Pump Installation

Your drainage system will also require a sump pump to get the water out of the basement or crawl space. The pump will need to be located in a location that will allow it to be connected to a drainage pipe that will exit to an appropriate location in the yard.  Caution should be noted if you want to connect the sump pump to the sewer system. In some jurisdictions it is illegal to use the sewer lines for connecting a sump pump. We can help you decide the best method for getting the water out of the sump and away from the home’s foundation.

Sump Pump Backup Power

Another thing to consider is when installing a sump pump is backup power choices. If you’ve lived in the area for a while you are probably familiar with power outages during large storms. These outages can cause your sump pump to fail when you need it the most. We can install a backup battery system that will keep your pump working even when the power is out. If your home is equipped with a backup generator we can also make sure that the circuit for your sump pump is connected to the back up power system. Having some form of backup power for your sump pump should be provided. We can discuss your options and cost when we prepare a free estimate.

Exterior Drainage Problems

Another area of your home that can contribute to interior basement flooding problems is outside of your home. Making sure your gutters and downspouts are in good working condition is important to keeping your basement dry. Gutters should be routinely inspected and cleaned. Gutters that are to small or dirty can cause an abundance of water to be poured along the foundation walls. This increases the hydrostatic water pressure in the ground. The more water that is in the ground the bigger the chance that you will have problems. So it’s important to make sure that your gutters and downspouts can handle the excess water running of the roof during a storm. Connecting the downspouts to drainage pipes that allow the water to freely flow to an appropriately graded portion of your lot is a very important step in waterproofing basements. Also correcting grading issues such as low spots along the foundation walls can help alleviate damp and flooding basements.
