As a homeowner, keeping your home maintained and free of damage can be a constant battle, especially with the changing weather patterns and extreme weather events that are affecting different areas of the country. But you can take some extra steps to waterproof your home's foundation and basement, which can be one of the biggest problems that occur to your basement. Here are some tips to help you keep your home basement dry and prevent water intrusion leading to moisture problems.
Install and Use a Sump Pump System
A sump pump is a great way to collect water seeping into your basement and crawlspace and pump it back outside of your home. There are several ways you can choose to install a sump pump in your home—this is a choice homeowners usually make when they begin to experience moisture leaking into their basement space. You can install a sump pump and drainage collection system on the exterior of your home, or you can install it inside your basement floor.
To install a sump pump drainage system on your home's exterior, you will need to excavate the soil from around your home's foundation down to the footers or foundation slab of the structure. Once the foundation is exposed, you would install a drainage tube or tiles containing perforations covered by gravel, which collects and drains into the connected sump pump any moisture present outside of your home foundation. The sump pump only turns on when the drainage tile collects moisture.
A drainage system within your basement floor requires you to cut out the concrete floor and dig a trench around the perimeter of your basement floor. Inside this trench, you can install the perforated pipe and gravel layer, just as in the exterior system. In this situation, the sump pump is usually located in your basement floor and pumps water outside of your home via a PVC drain pipe. Talk to a home waterproofing professional about your options and the best choice for your situation.
Apply a Waterproof Treatment Your Basement Walls
Another option to prevent moisture seepage into your basement is to add a waterproof treatment or layer to the concrete walls, which can be added to the inside or outside of your home. Before adding a waterproof layer to the exterior of your home, you will need the soil excavated from the foundation and the trench braced to prevent collapse.
It is not recommended to install exterior waterproofing during wet weather, as this can cause problems with water filling your trench. Make sure a professional exterior waterproofing contractor completes this during dry weather and adds a waterproof sealant or membrane layer to the outside of your foundation.
On the inside of your bare basement concrete walls, you can add a vapor barrier to keep any water draining down the concrete wall, which you would collect inside a floor drainage system. This waterproofing will also require a floor drainage system to be installed inside your basement.
Or as a DIY project, you can apply a waterproof sealant onto the bare concrete of your interior basement walls. This type of sealant coats and adheres onto the concrete, creating a non-permeable layer that forms to the wall and keeps out moisture. This type of coating needs to be rolled or sprayed onto your wall in several layers, allowing each layer to dry before applying the next.
Supplement Your Landscape Soil
A great way to prevent soil saturation from occurring outside your home, which is what leads to moisture permeating into the pores of your concrete wall, is to keep the water draining away from your home. This can be accomplished by adding extra soil to build up a slope around the outside of your home to promote water flowing away from the foundation. You can order soil from a local landscaping company or directly from a topsoil provider, which will cost anywhere from $7 to $12 per cubic yard.
