The system is designed to prevent the formation of unsightly cracks that can develop over time between the edge and the structure due to the natural contraction and expansion of the materials. These microcracks can compromise the visual continuity of the edge and quickly become a point where soil and moisture accumulate, encouraging the growth of weeds.

NatBoundaryLock, on the other hand, keeps the connection between the two elements stable and controlled, preserving the continuity of the edge and the clean aesthetics of the entire pool over time.
