To do this, use a sledgehammer to break up broken or damaged brick, or use a hammer and chisel to break away any cracked or damaged mortar. Once you break out the bricks or mortar, simply place them in a spare container so that you can dispose of them later. Small brick cracks are common and do not indicate foundation problems. That's because brick is naturally prone to expanding. If only a few bricks are affected by fractures, don't worry about it. Deterioration and structural foundation damage is probably not a concern. Chip Out Loose Mortar Position a flat utility chisel at the edge of the brick and drive it toward the relief cut to fracture and remove the mortar. Wear safety glasses and a dust mask and remove 3/4 to 1 in. of old mortar (more if needed) until you reach a solid base for bonding the new mortar. Step 1: Level the playing field by removing any loose or sunken bricks. Use a chisel to clean away old mortar from the brick sides. Fill the empty spots in the walkway or patio with a layer of sand and carefully replace the bricks. Use a level to confirm the bricks are set at the proper height before proceeding. You can repair hairline cracks in concrete with a grout made of Portland cement and water. Add just enough water to the cement to form a thick paste. Moisten the old concrete along the hairline crack with water for several hours before adding the grout.

Scoop a dollop of mortar onto a brick trowel or hawk, hold it up even with a bed joint, and push the mortar against the back of the joint with the tuck-pointing trowel.

Apply Polymeric Sand Over the Pavers Pour several small heaps of polymeric sand over the patio or walkway. Do not over-apply the sand, because the excess will be hard to remove. You can always add more sand, as needed. The goal is to completely fill the cracks between pavers, without leaving excess sand on the surface.

Method Use a completely dry surface. Put together a 4:1 (though some use 3:1) mix of builders sand and cement (do not mix with water! ) Brush across the whole area using a softer brush, filling all slab gaps evenly. Compact the mix into the gaps with a trowel. Repeat as above until all gaps filled and mix brushed off slabs.

If the crack is located closer to a corner and is wider than 1/8 in, it is probably not due to shrinkage but indicates a more serious foundation issue. If your vertical foundation crack is wider than 1/8 of an inch, call a professional to get it inspected as it may be a cause for concern.

Contrary to what you would think, buying a house with foundation issues isn't always a bad idea. Many buyers are not keen on having to deal with major repairs before they can move into their new home. However, if you play your cards right, buying a house with foundation issues can save you a lot of money.

Dampen the crack by misting it with water from a spray bottle then push the hydraulic cement mixture into the crack with a putty knife. Let this dry for an hour or two then add another layer of cement mixture over the crack. Use a trowel to make the cement patch level and smooth with the wall surface.

Foundation Cracks: Causes, Seriousness and When To Worry. Foundations crack for many reasons including unstable soils, poor drainage and settling. Cracks may indicate serious structural problems and others may be insignificant.

Paul says typical repair jobs cost between $15, 000 and $35, 000 (ours came in near the upper end of this range). But the terminal cases, where the foundations are in danger of crumbling, can cost $100, 000 or more. Foundation-repair companies offer various cures.
