CAN'T SAY I HAVE EVER HEARD OF THAT .WHAT I USUALLY DO IS DRILL HOLES AT THE END OF THE CRACKS TO TRY TO RELIEVE SOME OF THE PRESSURE THEN CUT INTO THE CRACK WITH A CONCRETE SAW TO OPEN IT UP SOME .DON'T CUT DOWN THRU THE TANK JUST A HALF AN INCH OR SO .THEN PATCH WITH A COMMERCIAL PATCH OR WHITE PORTLAND MIXED WITH MARBLE DUST.OPENING UP THE CRACK ALLOWS MORE PATCH TO GET A BITE. IF YOU'VE NEVER USED SOMETHING LIKE A RESCUE SAW WITH A CONCRETE BLADE YOU MAY WANT TO PAY SOMEONE FOR THIS JOB.NO MATTER WHO DOES IT THERE ARE NO GARANTEES A CRACK MEANS THE POOL IS SETTLING AND ONE PART OF THE POOL IS MOVING AND THE OTHER IS NOT.ADDRESS ANY DRAINAGE PROBLEMS IN THE AREA AS THEY WILL JUST ADD TO THE PROBLEM
The crack can also be injected with epoxy, which makes for a very solid repair.

Why are people worried about the corrision of steel in concrete bridges and buildings?
Because the steel reinforces the concrete helping to keep it from cracking all the way through. We know that concrete will eventually crack so we use steel to help it retain it's intended shape and function. If the steel corrodes to a point of weakness the concrete structure is also weakened.

How do you fasten 2 x 4 to concrete walls in basement?
One method to fasten timber to a concrete wall: You will need: * a hammer drill * a masonry bit * a timber bit * a pencil or marker * concrete fasteners: these could be expanding bolts that will grip the sides of the hole drilled into the concrete as they are tightened; bolts set into epoxy resin in the drilled hole in the concrete; or screws tightened into plugs hammered into holes drilled in the concrete * a plumb line or level * measuring tape or ruler # Measure the required location of the timber on the wall # Check with plumb line or level # Mark the location # Mark and drill with the timber bit at least two holes for fasteners (the number required will depend on the load to be carried and the size of the timber) in the timber # Locate the timber on the wall and mark the corresponding locations on the concrete through the holes in the timber # At these locations drill into the concrete with a hammer drill and masonry bit the correct depth and diameter for the fasteners you have # clear all dust and residue from the holes # Attach the timber using the fasteners. Note builders epoxy sets very quickly Timber should be separated from concrete by a moisture barrier such as damp proof course, plastic membrane etc to prevent any condensation on the concrete causing moisture buildup and rot in the timber
