HOW IT WORKS

do it yourself basement waterproofing systemThe most common mistake do-it-yourself homeowners make when waterproofing their basement is trying to push or stop the water with paints or patch-its. Waterproofing paints or membranes are hugely labor intensive and never last longterm. To permanently dry up your wet basement you need to think like the PROs! The SealOnce Basement System is the ideal do-it-yourself remedy to a wet basement because it relieves hydrostatic pressure and properly drains and collects water seepage just like the PRO’s without the big price tag!

As the soil around your foundation becomes water-saturated, hydrostatic pressure forces water through the joint where your floor and wall meet. SealOnce Basement System can cure that problem. Designed as a hollow baseboard, this easy to install DIY basement waterproofing channel collects the seeping water and quietly drains it to your floor drain or sump pump.

The only skill needed for installation is the ability to follow directions. Just seal the pre-molded corners and easy to handle main sections to the floor using the SealOnce Adhesive. With the SealOnce Basement System in place, walls can easily be paneled or finished. Drying up your wet basement is the first step towards a clean and healthy room ready for living, storage, and play. The SealOnce Basement System can turn your wet basement into a comfortable room suitable for your home and family.

COMMON HOMEOWNER QUESTIONS

For many homeowners the SealOnce Basement System is the first time they’ve had access to a professional-grade basement water control system they can install themselves and often have a few questions. Below are answers to the most common questions first time homewoners ask.

How will water flow if my floor is uneven?

SealOnce Basement System stands 4-inches tall to allow for uneven floors. As water around your foundation rises, it begins to flow into the channel. Water flows naturally toward any low spot or drain.

Will water remain standing in low areas of my SealOnce Basement System?

When the water stops flowing out the drain or sump pump, you know that the SealOnce Basment System has finished its work. With the water level now lower than the floor, any water left standing in the channel flows back out through the weep holes or joint where the floor and walls meet for poured foundations.

Will the SealOnce Basement System require maintenance?

The SealOnce Basement System is made of PVC, the same as the water pipes in your home. An attribute to PVC is that it will not support algea that causes odors. The SealOnce Basement System itself needs to maintenance.

How long will the SealOnce Basement System last?

The SealOnce Basement System is a permanent installation. Systems installed in 1965 are working today, just the way they did when originally installed.

Why do I need to drill weep holes?

Hydrostatic pressure is relieved in block wall foundations by drilling weep holes in the concrete block cavities at floor level. The hollow DIY basement waterproofing channel collects the seepage. The baseboard is not attached to the wall, it allows air to circulate within the block cavities to help keep them dry. It also provides a source of disposal for upper-wall moisture to enter the channel.

How will the SealOnce Basement System work with poured concrete, brick or stone walls?

SealOnce Basement System works with any type of basement wall because the main sections are not glued to the walls. They simply rest against the face of basement walls. The top of the system is left open to allow any water seepage from the face of the walls to enter the system. The top the main section curls back creating a mini-trough directing the water behind and into the channel.

Can I finish my basement after installing the SealOnce Basement System?

Absolutely! You can easily box out and frame around the SealOnce Basement System, install drywall and other finishings in your new basement.
