How Setting Soil Shapes Pool Repair Patterns In Lansdale
A pool excavation removes soil that has often been settled and naturally compacted for decades or even centuries before construction. The backfill that replaces it around the finished shell, no matter how carefully it is installed, simply cannot achieve that same natural density right away. Over the years that follow, the backfill gradually settles further as gravity, moisture, and seasonal cycling work on it slowly. This happens to some degree on every pool installation everywhere, but the rate and unevenness of that settling depends heavily on the moisture conditions in the surrounding soil throughout each year.
Lansdale’s position near both the Wissahickon Creek and Towamencin Creek systems, combined with the borough’s documented lower lying topography, means the soil in many residential neighborhoods holds moisture longer after storm events than the soil in higher elevation communities nearby would. Backfill soil that swells when wet and contracts when it eventually dries experiences more dramatic cycling in these conditions than backfill soil in a consistently drier environment would ever experience.
That more dramatic cycling produces more uneven settling over the years, which is exactly the kind of soil movement that has led specialized concrete lifting and leveling companies to maintain a dedicated presence in Lansdale specifically, addressing sunken slabs and uneven surfaces around driveways, sidewalks, and pool decks throughout the borough.
