Why Oreland Properties From the 1940s Have Oldest Root Systems Adjacent to Pool Plumbing
Every community we service has established trees on residential properties. What makes Oreland, PA specifically different is the age of those trees relative to the age of the pool plumbing that shares the same soil beneath them. An Oreland, PA property built in 1947 with oaks planted at construction has oaks that are now 79 years old. A mature oak at 79 years has a root system that extends underground across a radius roughly equal to the height of the tree and sometimes considerably beyond that on properties with consistent soil moisture from Sandy Run Creek drainage.
When a pool was installed on that same Oreland, PA property in 1964, its underground plumbing was placed in soil that already contained 17 years of oak root development from surrounding trees. From 1964 through 2026 is another 62 years of parallel development, root systems expanding through the soil while the plumbing joints were simultaneously absorbing 62 Pennsylvania thermal cycles and progressively losing the flexibility they had when the pool was new. The joint that was fully sealed and structurally sound in 1975 has been losing flexibility progressively with every thermal cycle since then. The root system that was 17 years old in 1964 is now 79 years old and considerably more extensive than it was at any earlier point in the pool’s service life.
This combination is what makes underground plumbing failures in Oreland, PA specifically likely to involve root infiltration as a contributing factor alongside the joint age and thermal cycle history. The root systems do not typically burst intact joints by direct force. They find the microscopic gaps that have opened at bonded connections as solvent cement aged, apply gradual outward pressure at those gaps over years, and gradually widen them into active water escape points.
