basement waterproofing

Nothing is worse for homeowners than finding water or moisture in their basement. Even the tiniest trickle or smallest puddle on the floor could herald bigger problems. Dealing with structural damage, toxic mold, and costly repairs can be heartbreaking. Rather than being sorry for overlooking this space, waterproof the basement, and you’ll live in peace. But what method works best for Denver, CO, homes?

Creating a dry and healthy basement may seem elusive when you’re up against perpetual moisture and occasional water from the outside. Your situation could get worse if you’re unsure of what basement products to use. Let’s see what options you have for internal and external waterproofing.

Interior Waterproofing

Starting with the interior, look for cracks or holes on your floor, basement walls, windows, and door. Ensure the basement is air-tight. If you notice cracks, ask your local contractor to seal and repair them.

Once you seal cracks, measure the humidity levels in the basement using a hygrometer. If it’s above 50%, get a dehumidifier and use it to bring down the humidity in your home. This can help prevent condensation, a problem that also sets the stage for wood rot, mold growth, and dampness. Where necessary, you might have to install a sump pump to prevent flooding. A lot of people overlook this measure, only to end up with flooded basements.

Exterior Waterproofing

While interior waterproofing arrests moisture and water from the inside, they do little to combat water from the outside, which can be a source of problems. Check your yard and see if it’s sloping away from your home. Otherwise, it’s going to send water right into your foundation. Excavate the soil around the perimeter of your wall and install a waterproof sealant, which is typically a polymer base. This should be done during construction, though it’s possible to do it later on.

Guttering systems can also boost your exterior waterproofing efforts. When these are installed properly, they will direct water away from the foundation walls. Proper maintenance is key to their functioning. Debris and falling leaves may cause obstruction to water flow, and this means water will collect along the perimeter of your home. Also, ensure the downspout extensions point away or are buried and direct water as far as possible.

Which Method is Right for You?

This depends on the condition of your basement and what issues you’re dealing with. Remember, no two homes are similar. A waterproofing method that works for your neighbor may not suit your home. It’s best if you ask your local basement contractor to assess your basement and recommend the most appropriate solution.

If it’s flooding alone, a sump pump might be what you need to stop water from collecting on your basement floor. If it’s high humidity, your best bet is a dehumidifier. As for cracks, other foundation repair methods may be needed to protect your home.

While each one has a different situation, the best policy is to undertake preventive measures right now instead of waiting for repairs. Buying time will only lead to deeper problems. In the end, you could end up with a damaged basement and huge repair bills.

Smarter ways to keep a basement dry

Taking a proactive approach to basement waterproofing means knowing what issues you’re up against and what strategies and systems you can combine to create a dry space. Using multiple methods offers the best protection against water and moisture. We strongly suggest you do the following:

Use an interior drainage system and sump pump – Combining both solutions makes your basement less prone to water damage. The interior drain will collect water that leaks into the basement through cracks on the floor or walls. In doing so, it discourages hydrostatic pressure from building around the foundation. Once the water is directed into the sump pit, the pump kicks on and starts draining it out.

Use membranes and coatings – While they can’t stop water from entering the basement, they can limit the volume of groundwater that seeps through the masonry walls.

Channel away from the foundation – Enhance the efficiency of your basement waterproofing system by rerouting water away from the perimeter of your home. Ensure gutters and downspout extensions are functioning properly to avoid overflows and backups close to your home.
