Warning Signs

Critical Planterbox Waterproofing Warning Signs

Recognize these early indicators of water damage before minor moisture issues cause expensive structural decay.

Damp exterior walls

Moisture showing on the outside of the planter box means the internal membrane has failed.

Salty white deposits (efflorescence)

Water leaching minerals through the brickwork or concrete of the planter.

Dead or struggling plants

Poor drainage due to blocked or failed systems can drown root systems.

Cracking brickwork

Structural damage caused by roots breaching the membrane and expanding into the walls.

Soil washing out

Muddy water leaking from the base indicates failed geotextile or missing drainage control.

Pooling water on surface

Indicates the drainage outlet is blocked or the soil is completely waterlogged.

Our Process

Our Proven 4-Step Process

From Problem to Peace of Mind

STEP 1

Interior Box Preparation

Planterbox interior walls and floors are cleaned of dirt, old soil residues, and loose mortar, followed by grinding to create a sound substrate.

STEP 2

Moisture Sealing & Priming

A heavy-duty epoxy primer is applied to seal damp concrete walls and prevent vapor pressure from destabilizing the waterproofing membrane.

STEP 3

Drainage & Penetration Detailing

Drainage outlets and wall joints are reinforced with flexible bond breakers and specialized sealant to withstand continuous root contact and soil pressure.

STEP 4

Root-Resistant Membrane Coating

We apply specialized root-inhibiting liquid polyurethane or torch-on bituminous membrane, protecting adjoining building walls from dampness and root damage.

Service FAQs

Frequently Asked Questions About Planterbox Waterproofing

Got questions about planterbox waterproofing in Sydney? Find technical answers regarding membrane specifications, curing times, and warranties below.

Standard membranes are easily breached by aggressive plant root growth and constant soil moisture. We utilize specialized root-inhibiting polyurethane membranes coupled with high-flow drainage cells and geotextile filtration to prevent root penetration and soil waterlogging.
Yes, absolutely. All soil, plants, old drainage gravel, and existing membranes must be completely excavated and removed. We need unobstructed access to the bare concrete or brick substrate to properly prepare the surface and apply the new membrane.
A drainage cell is a rigid plastic grid that creates a permanent void at the bottom of the planter. Covered with geotextile fabric, it allows excess water to flow freely to the outlet without soil clogging the drain, preventing root rot and protecting the waterproof membrane.
Yes. Plant roots are highly aggressive and naturally seek out moisture. They can exploit microscopic cracks in standard membranes or concrete, eventually expanding and fracturing the structure. This is why we exclusively use chemically treated, root-resistant polyurethane membranes for planter boxes.
Once our polyurethane membranes are fully cured, they become completely inert and non-toxic. They will not leach any harmful chemicals into the soil, ensuring a safe and healthy environment for your plants and vegetables.
We waterproof the entire internal floor and extend the membrane up the interior walls to at least 100mm above the intended final soil line. This ensures water cannot bypass the membrane when the soil is saturated or during heavy rainfall.
