Concrete Planter Boxes Waterproofing

Identifying leaking planter boxes

Many structures, both residential and commercial in purpose, have planter boxes. Planter boxes offer an office or block of apartments, the potential for an ambient space of various plants. However, as these plants are in planter boxes, not the ground, when one cracks, creating a leak, then there can be severe consequences if left untreated.

The predominant identifiers for leaking planter boxes are:

  •    Stains on the outside of the planter box walls (sometimes the paint will also blister)
  •    A leak is coming through your ceiling and it is not clear water, more of a brown colour (from the water travelling through the soil in the plater box)

Leaking Planter Box Causes?

Along with the above identifiers of leaking planter boxes, the most common causes are:

Tree roots and other plants

A root chases moisture trails through joints or any penetrations it finds. When it does it has the strength to tear a waterproof membrane apart, thus resulting in leaking planter boxes.

Structural movement

Movement of a structure can tear waterproofing membranes at the floor or connecting junctions. When torn, water travels freely, resulting in leaking concrete planter boxes.

Overwatering and heavy rain

Over watering or heavy rains can lead to water ingress, consequently resulting with leaking concrete planter boxes. Waterproofing easily solves this issue.
