Did mister builder waterproof the outside walls or damproof them?
And did they backfill with most-all gravel/sand OR did they backfill with same soil that was excavated?
Is your garage or a porch directly on the outside of either crack?
IF…if…if one or both cracks are where the garage or a porch is outside AND they only damproofed you may be OK per ‘water-intrusion’…for awhile,long as there is no further movement,long as crack(s) do not widen.BUT IF crack(s) widen a bit due to possible porch-footing leaning against wall or garage/driveway slab against wall or clay soil etc against walls then you prolly will leak…got that? lol
So instead of screwing around and taking any chances and hoping there isn
t any future movement/widening, id have
em waterproof the cracks, PROTECT YOUR azz. Down the road if there are any problems, mister builder will be long gone,wont wanna talk with you.
Here is a homeowner who had vertical crack,leaked. Mr builder looongg gone as Ernie Harwell used ta say http://www2.snapfish.com/thumbnailshare/AlbumID=228621104/a=122238283_111847456/t_=122238283
They only damproofed walls,big DIFF between damproofing and waterproofing AND they backfilled with same lousy clay soil that was excavated…never good.They did not pack any rod holes either ](*,)
Please do NOT buy,believe what builder might tell you,or others such as something like…‘just keep the grade sloped away and add longer downspout extensions’.
This homeowners GRADE is sloped away and builder boy even put in some sub-surface drain tile to try `n divert water away.Gotta fix/repair the cracks/openings!
Pics 19,20 See GRADE sloped away
Pics 3,4 Hairline vertical crack and YES, it leaked…we wouldn
t have been there/hired if it wasnt leaking.
11,12 See the crap CLAY soil, heavy chtt and it expands and contracts against the basement wall,could cause a crack OR, WIDEN an existing crack all by its lonesome self.
Also note ROD HOLES. Did builder fill/pack each rod hole with cement? Doubt it, so be aware in coming months/years any rod hole can,could begin to leak.

This is a control-joint. Most…not all builders do NOT seal/waterproof this correctly on the OUTSIDE. If YOU have this it would usually be on the 2 longer walls at-near middle of each wall, you should see a ‘V’ in walls unless builder or sub patched/filled this ‘V’ in,on the inside. Just another heads up.
Few pics from Army Corps Engs, Amherst NY…CLAY SOIL
I`d stay away from any inside injection/ptach job if thats whats offered
