There are pipe lining methods, but usually cheaper and long-term more effective to just dig up the broken place and fix it when in the house like this.
I would check first WHERE the water is coming from - that it is not an overflow problem due to partly blocked washing machine drain pipe causing overflow at the washing machine bay, down into the wall. Also, that you do not have a floor drain backing up due to a partial sewer pipe blockage - usually happens first with washing machine discharge volume, then as blocks off more progresses to overflowing from floor drains when tub is emptied, then toilet flushing, then showering and dishes, then using sink. If appearing only at the floor, I would look for a floor drain (possibly concealed under flooring) - else trace back from wetness up into walls or floors.
