We recently purchased a cottage. We knew there were foundation problems due to water infiltration (there was no surface water management to speak of). We are planning to rectify the roof drainage by installing gutters and downspouts. Also, regrading will need to be done to move rain water away from the house - what type of material I should use to fill in the extremely low spots (the previous owner dumped large quantities of mulch!!)? Also, it seems as though the walls of the foundation were never attached to the floor slab, so that the walls have somewhat buckled at ground level and are shifting inwards (with no apparent signs of dammage to the slab floor). At some point, we will raise the cottage and properly remedy the situation. In the interim, however, what is the best way of ensuring no further movement? Is there some type of tie-back system I should employ?
