50% or so of Injections in poured walls will re-leak, any part or all of a crack can widen. At least this builder did something, some don`t.
Injections are NOT what
s best for the homeowner short or long term, they are whats easiest and best for builder and many Inside water-diverting Co`s.
Yep, more difficult/laborious to fix cracks correctly on the outside, its called work, sweating one
s butt off and doing it right. Its a lil more costly to Mr Builder as well, that`s why they do what they do.
Add to that, MOST basement walls are not Waterproofed and backfilled correctly, among other things. Just about all homes-basement walls are, at best, parged or damproofed and not backfilled with most-all gravel. If basement walls were Waterproofed and backfilled correctly when built, as well as other important steps like using vertical reinforcing rod, homeowners would have LESS cracks, leaks,bowing walls. NOT talking about a ton more money either. The one
s in charge, like most of our politicians, either dont know,are being misinformed, and maybe don`t care. Same old story in this country
Cracks can occur from several things, from onset cause could be from poor backfilling practices like, the operator of backhoe/front end loader simply being too close to basement walls. Yes, using heavy equipment(the weight of) next to/near a basement wall causes an underground springlike force that is at least partially transmitted to basement wall, could cause damage/crack in basement wall.
Crack(s) could occur from compaction-process, compacting the soil could cause a crack in bsmt wall.
Crack(s) can occur within couple months or coming year or so from the settling of the soil against a basement wall. As soil settles with coming rains it compacts and creates pressure against the outside of the wall, sure it does Some are shrinkage cracks.
Sometimes thickness or depth of footings cause problems, weather conditions when built…lots of rain on site can cause more/future settling…and other factors.
“…Problem is that the pressure from the compacting process gets transmitted through the soil to the wall. Basement walls have been known to CRACK or fall over while earth is being dumped against them Or Compacted around them…”
“After compaction, Soil is under compression like a spring and…CONTINUES to push against the foundation as it tries to expand…in practice, sands and gravels densify or compact more readily than silts or clays, creating LESS of this springlike Force–one more good reason to use them for…BACKFILLING” …got milk?
–Careful on the Construction Site
“When there`s a heavy load on the ground next to a foundation, some of the PRESSURE is transferred to the WALL. During construction, bulldozers and trucks that come near a basement wall can add enough surcharge-pressure to damage the wall.A new building being built near an existing basement can also INCREASE the Underground pressure and damage the existing foundation…”
See what Yoder Group knows, 6th paragraph…
Or how about what this link says, see --Basement Walls and…
–Diagnosing the PROBLEM
among other things… “the appearance of foundation wall cracks does not necessarily mean that you have a structural problem”
