Interlock paver restoration in St. Catharines.

A practical guide to restoring the interlock you already have. Settled pavers re-leveled at the base, joints re-sanded so weeds stop, and the whole surface cleaned and sealed.

Why St. Catharines interlock settles

A large part of St. Catharines sits on clay-heavy soil. Clay holds water, expands when it freezes, and contracts when it thaws. A Niagara winter runs that cycle repeatedly, and each pass works on any weakness in the base beneath the pavers. A base that was rushed during the original install, or one where drainage was not set up to move water away from the house, tends to show its problems within ten to fifteen years as sunken spots, heaved sections, or a driveway that looks wavy across its whole length.

The pavers themselves are rarely the problem. Concrete interlock pavers are durable and often outlast the base by decades. The restoration case is almost always: fix the base, re-lay the original stone, and re-sand the joints. That is a fraction of what a full tear-out and replacement costs.
