π§± Is your interlock starting to separate, shift, or sink?
Many homeowners think adding more polymeric sand will solve the problem.
The truth?
In most cases, movement is a sign that the base underneath is failingβnot the stones themselves.
A properly installed interlock system starts with a strong foundation. When the base is built correctly, your patio, walkway, or driveway will stay beautiful and functional for years.
π‘ Quick Tip:
Fix the cause before fixing the surface.
A strong base = a long-lasting interlock.
