here i was surfing the net, interested in more info so i could install a short french drain on my side yard where some water accum. when there is some heavy rain. then i saw your note. you know doctors. even though i am retired we just can't keep our opinions to ourselves.
i have waterproofed 2 homes. the first was actually built on an undergroudspring so you can imagine the problems i had trying to dry that up.
we just move into a smaller home and in the past 8months had our smaller home water proofed.
this is what i have learned.
#1 you cannot stop water. it is too powerful a force. it can only be diverted. just pick up a bucket of water and feel the wait of that. then think the next time when the ground is saturated with water, the effect of the hydrostatic pressure on your home.
#2 your home is one of your biggests investments.
a little french drain in the back yard which i very labor intensive to put in, is not going to cure your problems unless you just have sliding glass doors where the water is coming in.
#3 you need 3 - 4 consults
make sure they drill holes in the bottom of the foundation and they should leave a gap between the wall and wair the lay the cement because occasionally water could seep through a crack. by leaving this little space with some plastic trim to catch it your basement or lower level should be bone dry. also you have to have a sump pump. in missouri, it is code for all new house to be built with sump pumps and waterproofed.
#4cost does not equal quality. i had mine done by a company that charge 2/3 what the others offered.
#5make sure you know where the are draing the piece of pvc to. if you have warm weather year round it won't be a problem. when selling your house the building inspector may not like where that piece of pvc is. i had to dig a ditch myself and make a little gravel pit under some bushes at my first house. this last house i yelled and screamed and made sure everything was done the way i wanted.
i used central states waterproofing 1800 649 5582
sorry i was so windy
if you want me to scan an image of the installation procedure just send me your address
although my scanner is not that great
