ITS up to you but i would drill ties in the left as you look in the
picture.Also drill some to the
steps.Leave the expansion joint to the right.Make sure to drill every
second or third step.
THE small ammount of concrete required will be sorted out by a firm
called MINIMIX.
YELLOW PAGES should have at least a couple of entries,or try the WEB.
THE larger READYMIX DEPOTS now do HALF A METER UPWARDS,
Make sure the new poured concrete does not dry too quick,Throw water
over it about three
times the next day to prevent cracking.also make sure you use SOAP OIL
ON THE SHUTTER.
so as it doesnt stick.
GET A GOOD QUALITY EPOXY RESIN WIYH APPLICATOR FOR THE STEEL INTO THE
STEPS it is far less messy and dries in minuets and sets like
steel,allow 6inch depth on drill.
