Do you work with lime based foundations ?
Yes we use period correct masonry cements with restorations. Lime foundation restoration and fortified cements with polymers. We offer lime European whitewashing , sealants or structural skins.
How do fix failing stone foundations ?
If the stones are loose we reset them by carefully removing the stones and failing mortar. Once the stone beds are clean and ready for new masonry cement we reset the stone and fill all voids or masonry joints.
My interior basement walls have soft flakey white powder in between the stones can this be fixed ?
Yes this is very common of early New England homes that used a masons mix which is hydrated lime and coarse sand. The lime initially acts as a great bonding agent and waterproofer. Over time the below grade portion of the foundation due to water saturation behind the walls become dry and flakey. The soft, powdery masonry joints between the stones cause the rocks to be loose and shift. The shifting stones in the foundation base causes settling and results in above grade cracks and shifting . The above grade portion of your foundation or the free standing section is reliant upon the foundation base being structurally sound. The dried out joints also cause leaks and flooding.
How do you repair this ?
We can restore your foundation by removing the loose flakey joint and reporting the stones. We use a type n masonry cement specifically designed for restoration purposes. If there is excessive water issues we can use fortified Portland cement based products to add a greater barrier that essentially waterproofs your stone foundation.

We never add any sealants before thoroughly repairing the foundation. Adding of a masonry sealant is not the solution to foundation repairs . Repointing all damaged joints and setting loose stones and making all required masonry repairs is the only true answer. If this vital step is not in place the sealants will not last and fail.

We then carefully dismantle the failing section. Also we remove any adjacent back pressure to allow for new construction of foundation walls. We dispose of excess debris and bring in additional stone or new brick if needed.
Before we rebuild foundation walls we install a spread footing or steal reinforced footings.
The foundation base is then built up to grade height. We are careful to waterproof the exterior side 3ft below grade to help with ground water infiltration . At grade height we then tie in brick or stone work as required with close attention to matching brick, mortar and bond of brick or stone.
Upon completion of foundation rebuilds we regrade the exterior if possible so water sheds away from the foundation. Waterproof coating can be added if desired.
What are structural foundation repairs ?

Having the skill set to match materials and install new brick, block or stone is vital in masonry restoration. When rebuilding exterior foundation walls it takes care and masonry precision to tie in brick and stone courses for a seamless match. Knowing load weights, bearing points, lateral load weight and carrying compacity in foundation construction is also essential in rebuilding foundation walls.
Spalling bricks can be repaired or replaced with new bricks. Spalling bricks occur when soft bricks retain moisture and sections of bricks fall off or spall. The spalling brick in foundations is caused by ground water at the grade base of the exterior. Over the years the bricks due to excessive moisture softens the clay and bricks can crumble. Massachusetts foundations were built with stone bases and brick above grade foundations for a more pleasing look . Brick laying allowed for more accuracy in layout of architectural plans. When repairing damaged bricks that have spalled, we remove all loose or deteriorated clay. If a brick is beyond repair we can easily add bricks. Spalling brick sections can be cleaned and treated with fortified masonry cement. We can add protective layers of cement coating to repair the structure of the brick wall and an effective barrier to moisture and future damage.

Ground level where the foundation base meets the free standing wall sections of a foundation is a common problem area we commonly repair. Over the years ground water causes damage and deterioration of foundation masonry joints. The loose joints cause shifts, cracks and leaks.

Being stone masons who have been building and repairing stone walls and foundations for three generations in Massachusetts we know what causes cracks in foundation walls, bowing, sinking, leaks and foundation failure.
Foundation problems typically start below grade with settling of the foundation base. Most Massachusetts homes have a 7ft foundation walls with 4ft below grade and 3ft. free standing. The four ft. below grade is essentially a stone retaining wall that acts as a footing for the 3ft of above grade. Over time ground silts and weaken the masonry joints in the often lime based foundation walls and cause leaks, cracks and shifting. Foundation base shifts below grade cause the above grade portion to crack, sink or shift which is are all signs of foundation failure.
The below grade foundation bases become dry and flaky over time and loose strength and bonding ability this causes the masonry cement to fail and stones loosen. Stone shims that were holding building stones in place will fall out and cause joint stress resulting in cracks and loose stones.
