s 'Karen Evil 9' ...welcome back my friends to the show that never ends were so glad you could attend come inside,come inside…come inside the show`s about to start, guaranteed to blow your head apart :mrgreen:
back to school… http://www.askthebuilder.com/B10_Forces_Harmful_to_House_Foundation_Footers.shtml
“gravity,soil swelling,soil collapse,frost heaving,hydrostatic pressure etc can cause serious harm to footers and foundations”
“many soils absorb vast quantities of water and this added water, combined with the soil, pushes against your foundation wall. This force is commonly referred to as hydrostatic pressure”
What does NOT absorb vast quantities of water? #-o
What applies the LEAST lateral pressure against a basement wall? #-o
Peastone-gravel,sand…good answer, good answer
“coarse grained, well-drained soils like sand & gravel apply the least lateral load”
http://www.yodergroup.com/concrete.asp 6th para
" we firmly believe a foundation should be backfilled with washed gravel(NOT dirt) from the basement floor level all the way UP to within 2-3" of finished grade outside…this is especially important, if not CRITICAL, with soils having high clay content…This type of DRAINAGE prevents trapped water and saturated soil next to foundation from building up horizontal hydrostatic pressure Against the Wall. This pressure will crack walls, cause leaks, and in a worst case collapse the wall inward"
" Many, many consumers THINK they have waterproofed basements, when in fact they simply have been damproofed"
" there is a Significant Difference between damproofing and waterproofing"
" Thousands of homeowners THINK they have a waterproofed foundation when in fact they do not"
“the backfill of choice is sand or gravel…unfortunately most builders backfill with the original soil that was excavated”
-Why worry about water/moisture in basement- Possible causes
Hydrostatic pressure- rainwater seeps into the soil and builds up pressure against your foundation walls. This hydrostatic pressure can exert tons of force on your foundation.
Cracked and buckled walls- Hydrostatic pressure can press against your foundation walls, even buckling of the walls and flooding. Heavy, wet soil continually presses against your foundation walls…"

Questions- Do you use outside excavation?
Should i have the outside of my basement walls sealed?
Their expert answers :mrgreen: …“NO! It is not only unnecessary and expensive but doesn`t permanently dry up your basement”
…No, this work was done when your house was built. It didn
t work then and wont work now. The sealing of basement walls was never meant to be a permanent solution"
Now, you talk about a good, self-serving bsht story. They either do not get that the outside was at best ONLY damproofed or parged and, was Not backfilled with peastone which…ahem, causes basement walls to crack,bow etc OR they don
t want you to knowcos they only do Inside drain tile/baseboard systems.
I`ll ask again :mrgreen: …can ANY Inside system stop/relieve/prevent lateral & hydrostatic soil pressure, and tree roots, which are on the outside of basement walls? Huh? lolol NO!
Can ANY Inside system stop/prevent water that enters say, through cracks `n other openings on the outside of hollow-block walls? Huh? NO!
Will ANY Inside system help stop mold? NO, Water will still enter these outside cracks after they install any inside system.
Will ANY Inside system help stop radon gas,efflorescence,termites etc?
NO! Because they don
t go Outside and seal/waterproof the cracksn other openings that allow water,radon,insects from entering.
