Excess moisture in the soil around your home and a high water table can both contribute to moisture problems in your basement. As keeping your basement dry is a high priority as a homeowner, here are some tips to help you keep your basement interior dry and free of moisture problems from the soil.
Interior Moisture Block and Diversion
Within your basement space, there are several different methods you can use to prevent and divert moisture from damaging its interior. If your basement walls are unfinished and unpainted or unsealed concrete or masonry brick walls, you can fill and patch any visible cracks with a hydraulic cement. Press it into the cracks with a trowel, or squeeze it through cracks with the applicator tip on the tube.
Another type of sealant to waterproof your walls is a thick acrylic paint sealant you can roll or brush onto your concrete walls to form a hard cured layer. There are also silicate-based sealers that soak into and chemically react with the concrete of your walls to form a hard barrier after it cures.
If your basement concrete walls have been painted, you can choose to apply a concrete waterproof coating that adheres onto painted surfaces. This mixture comes in a tub of dry product that you mix with water to create an application similar in consistency to wet concrete. Then, you can apply the mixture onto your walls where it dries to form a hard waterproof barrier.
Another method to block interior moisture seeping through your basement walls is by applying a plastic sheeting vapor barrier. Then, as any condensation collects on the interior of the plastic runs down into a collection drain around the perimeter of the wall. The water in the drain flows down to a sump pump installed inside the floor where it is pumped to a site outside your home.
Roof Drainage Prevention Strategy
Waterproofing your basement through various interior methods is helpful for keeping your home dry and protected, but preventing much of the moisture from entering your basement can be an even smarter method. Diverting outside groundwater and roof runoff from entering your home's foundation and basement stops the problems before it becomes an issue.
Check your gutters and downspouts on your home to make sure they are working appropriately to drain water from your roof and out away from your home's foundation. If you can check your gutters in action during a rain storm, look for any sagging gutters, or leaks from cracks and holes in the gutters and have them repaired as soon as possible. You can also turn your garden hose onto the rooftop and watch where the water flows. Precipitation that is allowed to fall upon the soil around your home's foundation will saturate the soil until water seeps into cracks in your home's foundation.
Next, you should watch how the water drains from the gutter downspouts to the soil around your home. Your home's gutters should at the least have a splash plate positioned where the water runs from each downspout. This prevents the water from eroding the soil immediately below the downspout and, instead, sends it out in different directions. You can also collect the rain water in a large rain barrel.
It is recommended to install a downspout diverter or drain pipe onto the bottom of each downspout to deliver the water to a point away from your home's foundation. Experts recommend a diverter to move rain water at least five feet away from your home's foundation.
It is also recommended to landscape the soil around your home to build a slope away from the foundation and basement. This helps water to flow downward and away from the walls of your basement, preventing your basement from receiving interior moisture.
