My driveway had been slowly sinking for two years and I kept putting it off. K Bros came out, found the drainage problem underneath and restored the whole surface. The way they realigned every single stone was impressive. Six months later it still looks brand new.
Our patio was cracking and the weeds were out of control. K Bros didn't just patch it — they dug up the problem area, fixed the base, re-laid the stones and used a proper polymeric sand finish. You honestly cannot tell where the old stones end and the repaired section begins.
The front steps of our home were crumbling and had become a real safety issue. K Bros rebuilt them from the footing up, matched the stone perfectly and the whole thing is solid. Professional crew, tidy job site and they finished on schedule.
A full circular walkway rebuild in Newmarket deteriorated stones, crumbling edges and a failing base replaced with precision-laid interlock. Drag the handle to compare.
Newmarket's freeze-thaw cycles destroy interlock bases. We correct the shifting and sinking at the source so it doesn't return next spring.
From weed-ridden joints to unlevel stones, we re-level and restore your outdoor space with materials that hold up season after season.
Every interlock repair in Newmarket is backed by our written 3-year warranty. If it moves, we come back and fix it at no charge.
A full large-format patio rebuild cracked slabs and failing joints removed, base corrected and compacted, then new stone laid to an exact finish. Three stages, one complete transformation.
Before
Large-format patio slabs cracked across 40% of the surface. Years of weed growth had destroyed the joint integrity and begun undermining the base. Water was pooling near the foundation.
During
All slabs removed, base excavated and re-graded for proper drainage slope. Fresh angular limestone laid and plate-compacted to specification. String lines set to ensure precision level across the full area.
After
New large-format slabs laid to under 3mm level tolerance. Clean tight joints filled with professional-grade polymeric sand. The surface is structurally sound, visually sharp and backed by a 3-year warranty.

Start Your Restoration ProjectThere's more to fixing interlock than pulling up a few stones and dropping them back in. Here's what actually happens on a K Bros job in Newmarket — and why every step matters.
Before we touch anything, we assess the full picture: base depth, drainage patterns, soil conditions and the true extent of damage. Most interlock problems trace back to base failures or drainage issues. Treating just what you can see is why so many repairs don't last.
Affected stones are carefully removed and set aside where possible for reinstallation. The bedding layer is cleared down to the base. Pulling stones by hand or with the wrong tools chips and cracks the surrounding stones that are otherwise fine.
The sub-base is regraded, compacted and rebuilt with fresh angular limestone where needed. Getting slope right for drainage while maintaining uniform depth takes experience and the right equipment. This is the step most homeowners skip entirely.
Stones that are damaged beyond reuse get replaced with matched material from our supplier network. Getting colour, texture and dimensions right so the repair blends in takes product knowledge and supplier relationships most homeowners don't have access to.
Stones go back on fresh bedding sand aligned to the existing pattern. We work to under 3mm level tolerance across the repaired area. Every stone gets physically checked for stability before we move on.
Professional-grade polymeric sand is swept into the joints and activated with water. This locks the stones together and stops weed growth permanently. On stone steps, mortar joints get repointed with a matching compound.
A senior team member walks the job before we pack up: level, pattern consistency, joint fill, drainage slope. Once everything checks out, your 3-year warranty is activated and documented. We don't leave until the job is right.
Whether it's a sunken driveway, a cracked patio or front steps that have seen better days, K Bros handles interlock repair across Newmarket and the surrounding area with a 3-year warranty to back it up.
