    I am thinking of using almost a second vapor barrier on basement walls

    I have had an engineer examine the situation. He said everything I am doing is very OK. He said I could use a breathable material on the inside brick wall. (waterproof but not moisture proof) Best Regards, Steam Bryan

    I am thinking of using almost a second vapor barrier on basement walls

    Well, I'll bring in an engineer for a visit and verbal advise. His gut feel is worth the price. Regards, Bryan

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, Thanks again, Two of the three walls are bearing walls. Now, I understand what you are saying. Makes perfect sense. Regards, Bryan

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, Thank-you once again! I am over 65 with a bachelor's and recently retired. I am OK with thermodynamics but forgot anything I knew about Vapor Pressure. Your help is greatly appreciated. On the property line is a set of cedars. I have to build up to have a downward slope so much that...

    I am thinking of using almost a second vapor barrier on basement walls

    TXStructural, bowed in two inches at mid-height everywhere, basically the full length of three walls. It is out of plum buy 1 to 2 inches. The next house is 12 feet away. It is about 3 feet higher on an even slope. next door is dumping water onto my property. Oldestguy, Thanks again. Regards...

    I am thinking of using almost a second vapor barrier on basement walls

    a2mfk, Thanks for the info! I am doing it in phases. 1- Fix surface drainage. + Start straitening the wall. + test for Radon. 2-examine Radon results. If high, go the above epa route. If low: A- go with Vapor barrier against wall ending in French drain. I will have drilled holes in...

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, Thanks again for your advise. If I use a foam sheet under the soil, Do I still need bentonite? My property line is six feet. I am thinking of installing foam for the 6 feet. Regards, Bryan

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, Ron, a2mfk, Thank you all for your great insight! I have decided not to double vapor barrier after Oldestguy's wise advise. a2mfk, The wall needs to be braced. Or, history might repeat itself? But, I could brace with carbon stripes every 4 ft. My water surface drainage is bad. I...

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, I did read the French Drain stuff, but only found one thread on inside French drain. The problem was not the drain but an oil pipe installation? The drain had no problem functioning. I would like to hear your information on waterproofing the surface. The walls have bowed in 2 inches...

    I am thinking of using almost a second vapor barrier on basement walls

    If the moisture does not drain, I am thinking of putting a humidifier attached to the French Drain??

    I am thinking of using almost a second vapor barrier on basement walls

    Oldestguy, The house has no surface drainage. I am correcting this with downspouts that remove most of the roof's water over 12 feet away. I will raise the slope on the outside perimeter. The walls are damp even halve way up so I thing drainage is a big factor. But, I suspect that the slab might...

    I am thinking of using almost a second vapor barrier on basement walls

    The double vapor barrier will have a bottom drain Please see attached. I do not want to trap the moisture. Bryan PS:I changed my handlehttp://files.engineering.com/getfile.aspx?folder=c49d5fd2-4c1e-42e0-aca7-cb9dd2e73fd9&file=Double_Vapor_with_drain_0001.pdf

    I have on old house heated by forced air oil furnace. The furnace is in an unfinished part of the basement which does not have an air duct that comes from outside to feed the furnace. the duct going from the furnace to the cheminey is 5" dia. I see different duct designs to bring in the air...

    cast iron piston ring leakage table

    Thank you Bud for your response. I think your hydraulic presses leakage is high but within reason. When applying your rule of thumb to your presses I get a theoretical leakage of about 0.2 gal per min? Am I missing something? Bryan

    cast iron piston ring leakage table

    Does anyone know where I can get leakage infromation for cast iron piston rings in large hydraulic service?

    piston ring low leakage in slow hyraulic service

    I would like to know the ring design used to reduce leakage in large slow moving hyraulic service. How do we calculate the leakage? How many rings should be used for a pressure of 300 psi? Is there a chart to know how many rings to use for a given pressure differential?

    vent condenser or vacuum pump?

    Wow! You certainly know your vacuum. My knowledge about it sucks. (Excuse the pun) The tank is better referred to as a separator. The stream coming in is a mixture of condensate and steam from a paper machine dryer section. Actually, I cannot increase the pressure of the tank above 5 psig or I...

    vent condenser or vacuum pump?

    Dear rmw, Thank you for your response. It is most informative. Yes, the steam is saturated when it enters the flash tank at a steady rate. The condenser sits on top of the tank and dumps the condensate back into the same tank (differential is zero). The tank is maintained at 12 psia. by...
