The Problem With Traditional Shotcrete Retaining Walls (and What Basepro Is Doing Differently)

Why This Matters

Retaining walls form the backbone of any basement build. In Melbourne, most basements are built using shotcrete walls, but are they really the best solution?

At Basepro, we’ve seen first-hand how traditional shotcrete retaining walls lead to problems:

• Water leaks and damp basements

• Patchy finishes that ruin internal aesthetics

• Delays caused by weather and on-site variables

That’s why we designed a precast concrete retaining wall system to give builders, developers, and homeowners a smarter alternative.

The Problem With Shotcrete

Inconsistent Quality

Shotcrete is sprayed on site, which means the quality depends heavily on:

• Weather conditions (too hot or wet can compromise the finish)

• The skill of the crew

• Site access and environmental factors

This often leads to variable finishes, some areas smooth, others rough or porous.

Waterproofing Headaches

Shotcrete alone isn’t waterproof. Because of its porous texture, waterproofing membranes often struggle to adhere properly.

Even a small error in application can allow water ingress, leading to mould, structural damage, and expensive repairs later.

Slower, Riskier Installation

Shotcrete requires:

• On-site formwork

• Curing time

• Weather-dependent work schedules

The result? Delays and cost overruns, a serious problem for builders and developers working to tight timelines.

The Basepro Precast Solution

We designed our precast concrete retaining wall system to address these challenges:

Superior Finish

Our panels are factory-made in controlled conditions, ensuring a smooth, consistent surface every time.

This is ideal for basements where the finish matters.

Designed for Better Waterproofing

Our system integrates waterproofing from the start:

• Smooth surfaces allow membranes to adhere properly

• No cold joints or spray irregularities

• External drainage systems designed in tandem

This results in basements that stay dry for decades.

Faster Installation

Precast panels are delivered ready to install:

• No weather delays

• Reduced time on site

• Predictable timelines and costs

Builders and developers can stay on schedule and on budget.

Why Basepro Is Different

Unlike traditional basement contractors who patch together multiple trades, Basepro handles it all:

• Design and Engineering

• Excavation and Retention

• Precast Wall Installation

• Waterproofing and Suspended Slabs

One team from start to finish. One contract. One point of accountability.
