Stone Foundation Repair & Historical Repointing
The fieldstone and limestone foundations beneath many Coopersburg homes have been doing their job for over a century. But the lime-based mortar that binds them wasn't designed to last forever — especially not through Pennsylvania's relentless freeze-thaw cycles. When mortar deteriorates, water seeps in, freezes, expands, and gradually turns solid masonry into a structural liability. Our stone foundation repointing process involves carefully raking out failed mortar to a proper depth, then packing fresh mortar that matches the original in composition, color, and compressive strength. We use historically appropriate lime mortars on older homes because modern Portland cement is too hard and inflexible — it can actually damage softer historic stone and brick.
