I posted awhile ago about the cracks in my basement and stuff. Well I
finally removed the carpets and sealed up the cracks with a polyeurothane
based caulk. I also used a Radon Seal (clear liquid based solution) over
the entire foundation.
My radon levels are better but not by much. My long term reading (over a
month) is averaging around 4.5 pCi/L . I have a radon monitoring gadget I
bought to measure these levels. (Safety Siren Pro 3)
My question is... Is it possible I could get away with just installing a
Radon Fan since my levels arent too way? Anything over 4.0 is considered
not safe. I have a radiant heating system...so they cant drill down into
my basement to install anything. Im also thinking about getting a
fireplace installed since I have everything stripped down in my basement.
Maybe I should have the fireplace installed first ? Maybe they will have an
alternate solution to the radon fan or will be able to install it themselves
when they make the opening for the fireplace ? Im just hoping I could get
away with just needing a fan for this solution.
Eventually im going to install Pergo wood flooring down there, so that in
itself my help the levels a little aswell. (by the way I dont have any
water problems down there in the basement..even when it rains alot)
Any expertise is appreciated.
Each case it different, but I would think the fan/vent will do it.
Around were I am sealing and a fan/vent is the usual approach.
I do worry about your flooring idea, but if you do the fan/vent system
just right, it should also help reduce humidity.
Before going ahead with the floor I suggest you take some plastic and
duct tape it to the floor, about 1 foot square. You may want to do it
several places around the area you are considering putting down the
flooring. If after a few days it is not damp under the plastic, you should
be good to go. If it is damp, I would ask your local flooring supplier for
get a interior french drain if theres any question of ever getting
misture or water in the basement..........
otherwise all your finish efforts will be a waste of money
you cant seal water out of a basement, just move it to somewhere else
It would be good if you can get a copy of the radiant heating plan that was
installed in your basement floor. It could give you an idea of where you
could open a hole in the floor. Keep in mind that the plan may not exactly
match the location of the actual installation, but it may provide some clue
of gaps probably near where the pipes attach to a manifold. Then dig through
the concrete very carefully.
I have no idea where to go to get a copy of this ? There wasnt even a
blueprint of the house when I purchased it. It was built in 1993 and I was
here in 2003.
Does anyone know what the alternative radon solutions are called when you
cant dig down through the concrete? I would like to google them and have
some knowledge before I call over the radon dude.
You didn't mention anything about a sump pump. That is where Radon enters
In Iowa I just sold a house and the radon levels were too high. Despite
the ease of installing a venting system I was required by law to have it
professionally installed for $1500 for less than $200 worth of equipment.
If I had installed it before the inspection I could have done it myself.
Government governs best when it governs least.
one could dig a hole along the foundation and drill under the slab or
basement floor inserting a perforated pipe. seal entrance bvent as
usual. pipe and fan out the roof.
if the home has a sump pump you pull vacuumn on the sump.
