Why Our Licensed Block Wall Waterproofing Is a Cut Above the Rest

At SuperiorWaterproofing, we provide professional block wall waterproofing services in Brisbane or Gold Coast designed to protect your property from water damage, dampness, and structural deterioration. Concrete block walls are durable but naturally porous, which means they can easily absorb moisture over time. This often leads to problems such as efflorescence, cracking, mould growth, paint blistering, and general structural weakening. Without proper waterproofing, water can seep through joints and pores, affecting both the strength and comfort of your building.

Waterproofing Project for a Residential Retaining Wall

Professional Block Wall Waterproofing for Long-Lasting Protection

At Superior Waterproofing, we specialise in waterproofing for block walls that protect your property from water ingress, dampness, and structural deterioration.

Our Waterproofing Solutions

Cinder Block Waterproofing

Sealing and protecting cinder block walls from water infiltration, moisture damage, and structural decay

Concrete & Cement Block Waterproofing

Concrete blocks are porous and absorb water, so without waterproofing, they risk structural damage and surface deterioration.

Besser Block Waterproofing

Besser blocks are highly porous and have multiple mortar joints, making them vulnerable to rising damp and efflorescence. Waterproofing Besser blocks can lead to significant savings by preventing costly renovations.

What We Waterproof?

Basement, Cellars and foundation walls

This is the most critical area for concrete block waterproofing. Below-grade walls are subject to constant hydrostatic pressure and capillary action from surrounding soil and groundwater

Cement Block Retaining Walls

Hold back heavy soil and face extreme water exposure, receive tailored heavy-duty waterproofing and drainage solutions.

Wall-to-Slab Junctions

Where block walls meet concrete slabs—critical for stopping rising damp and lateral seepage.

Wall Joints and Flashing

We pay meticulous attention to expansion joints, control joints, and areas where the block wall meets different materials.

Why Block Wall Waterproofing Matters

Prevents Water Infiltration and Damage
Concrete block walls are porous — they naturally absorb moisture. Without proper waterproofing concrete block walls outside or inside, water can seep through cracks, joints, or capillaries in the blocks. Over time, this causes structural weakening .

Protects Against Mold and Mildew
When moisture seeps into walls, it creates the perfect environment for mold and mildew growth. These not only cause unpleasant odors and stains but can also lead to Health issues, such as respiratory irritation or allergies.

Extends Structural Lifespan
Water exposure accelerates corrosion of reinforcement bars and cracking within the masonry. Over time, this compromises the strength of the wall. By sealing block walls with waterproof coatings or membranes, you reduce costly structural repairs.

Saves on Maintenance and Energy Costs
Dry walls act as better insulators. Moisture-laden walls conduct heat more easily, forcing HVAC systems to work harder to maintain comfortable indoor temperatures. Proper waterproofing for block walls lowers energy bills.

Frequency Asked Questions

What is the best method for waterproofing concrete block walls outside?

The most effective methods of waterproofing concrete block walls outside include flexible membranes, and penetrating epoxy sealers. These systems create a moisture barrier while allowing the wall to breathe—ideal for exterior exposure.

Which products are best for waterproofing concrete block walls inside?

Effective options include cementitious waterproofing coatings, negative-side membranes, and crystalline sealers. This method of waterproofing concrete block walls inside are designed to resist hydrostatic pressure and block moisture from entering through the wall.

Can concrete block waterproofing be done on both interior and exterior walls?

Yes—concrete block waterproofing is effective on both sides. Exterior waterproofing blocks moisture before it enters, while interior waterproofing helps manage seepage when outside access is limited.

Why is waterproofing exterior cinder block walls necessary?

Cinder blocks are porous and absorb moisture through capillaries and mortar joints. Waterproofing exterior cinder block walls prevents water infiltration, rising damp, mold growth, and long-term structural damage.

Can waterproofing cinder block foundation stop existing leaks

Yes—when combined with proper surface preparation, crack repair, and drainage improvements, waterproofing cinder block foundation can stop active leaks and prevent future moisture problems.
