How To Repair Interlock

Foundation Repairs
Pavers need to be removed in order to repair interlock foundations. Compaction, foundation depth, aggregate size and grade are potential foundation problems. Once completing the repair we relay the pavers and joints.

Polymeric Sand / Interlock Joints
Polymeric sand needs to be replaced periodically. We pressure wash the old material out from the joints and replace it with new polymeric sand. There are many different qualities of polymeric sand. Our repairs last because we use high quality products, also modern polymeric sands far outperform stuff that was used 5 years ago.

Stained, Dirty Pavers
Pressure washing is the best way to clean old and dirty paver surfaces. It is important to take special precautions to avoid damaging the polymeric sand filling the joints between pavers.

Sinking Edges
Interlock edged are susceptible to losing base foundation material through erosion. Without a solid foundation, the pavers sink into the ground. To remedy this we repair the foundation and install edge restraints preventing foundation erosion.

Cracked Slabs
Broken slabs are fixed by removing the damaged tile and replacing it with an undamaged one. We replace damaged pavers and slabs from suppliers like Techo-Bloc and Permacon. Sometimes products are discontinued and difficult to find. If this happens we can ‘match’ to a similar product or take an unbroken slab from an area that is out of sight.
When landscaping contractors won’t honour their warranty we are here to provide affordable interlock restorations.
