Why does tar waterproofing not last?
Tar Waterproofing Is Brittle – Tar waterproofing membranes has no "give" and cracks eventually develop as the concrete constantly contracts and expands and the house settles. Similarly, tar paper or pargeting (a layer of mortar) on block walls are inelastic and crack.
What happens when water moves through concrete?
When water migrates towards embedded steel, it rusts, expands and cracks the concrete. Efflorescence Signifies Water Seepage – Water penetrates the pores in concrete, dissolves alkalis, and enlarges the pores. As concrete ages, it becomes more and more porous.
How long does a waterproofing coating last?
Elastomeric sheet membranes separate as the alkalis attack the primer and taped joints and their service lives are guaranteed for only 5 to 10 years. In the end, the concrete is on its own.
What is radon sealer?
RadonSeal Concrete Sealer preserves new concrete and it protects concrete against the gradual deterioration caused by groundwater. Sealing the concrete early on, particularly before finishing the basement, will help avoid future headaches! If you have a brand new basement, now is the best time to prevent future moisture problems, to waterproof and strengthen the concrete, reduce cracking, efflorescence ("white powder"), dusting and to preserve the concrete.
What causes a basement to leak?
Hydrostatic Pressure – When water accumulates around the foundation, hydrostatic pressure builds up and causes the basement to leak. Clay-rich soils do not drain well and hold rainwater right against the foundation walls. Water pushes its way inside through any cracks or joints and the pores in concrete.
How long does it take for a concrete wall to dry before waterproofing?
Afterwards, allow the sealer to initially cure and for the concrete dry before applying the exterior waterproofing coating (2-4 days).
How much does it cost to install a sump pump?
Install a Sump Pump ($900–$1,500) – If your water issue is serious (a high water table), you will need to purchase and install a sump pump. Sump pumps drain water from the gravel bed underneath the basement floor. Relying on one sump pump, however, is risky, particularly if your basement is finished! The pump or the grid may fail during a severe storm or spring snow melt. Installing a backup, either a battery-powered backup sump pump or a water-powered backup sump pump is a smart decision and inexpensive insurance.
What does it mean when you see white water in your basement?
You may also notice spots of efflorescence (white "powder" or "whiskers") on the concrete surface which is a telltale sign of capillary water and water vapor. If this sounds all too familiar, now is the time to act before your wet basement gets worse making repairs much more difficult to do.
What is a weak link in a foundation?

How does radon seal work?
RadonSeal works by penetrating deep into the concrete (up to 4"), chemically reacts with lime and alkalis, expands inside the pores, and cures as a mineral. It waterproofs concrete internally against water seepage, water vapor, and even against radon gas.
How to speed up concrete drying time?
You can speed up the drying time by drilling weeping holes in the bottom of concrete blocks, installing a fan in the basement to improve evaporation, or simply waiting for dry weather. Once the concrete is sufficiently dry, seal the porous concrete foundation walls with RadonSeal Penetrating Concret Sealer.
Is latex paint good for concrete?
Latex-based waterproofing paints are too soft for floors. And if you apply an epoxy or urethane coating, concrete floor paint, or concrete overlay, years of water vapor pressure and efflorescence coming through the concrete pores will soon enough make it to fail, crack, or peel.
Is radon sealer waterproof?
Rado nSeal is not your average cement waterproofing sealer like those found in big box stores. Waterproofing paints, cementitious coatings, and membrane coatings will eventually loosen, crack, or peel, as they are pushed off by hydrostatic water pressure, trapped water vapor, and efflorescence.
Can you paint basemen walls with radon seal?

Cement block is extremely porous, it requires 3 coats of PermaFlex which costs approx $01.14 per sq'. Most all basements have a cold joint where the wall meets the floor.
Does ventilation reduce radon?
Given that the testing procedure requires that one keep windows closed and minimize the usage of doors, it seems that ventilation of any sort will reduce radon concentration. That said, radon density is about 8x of the earth's atmosphere, so it's not going to automagically find its way up your chimney.
Is radon mitigation a mitigation system?
The EPA recommended mitigation for radon is indeed a mitigation system with a fan...as one can be assured that the radon will continue to be reduced unless the fan stops working...which saves a lot of testing. Any other method will require periodic testing to make certain the level remains below 4.0 pCi/L.
