Water Woes Averted at a Commercial Property, Wyong
When it comes to commercial plumbing, prevention is everything.
At this commercial property, our team was called in to investigate some concerning water-related issues at a busy commercial site. What we found were two significant plumbing problems that, left unchecked, could’ve led to major disruptions—and hefty repair bills:
- Internal water ingress, and
- Stormwater drainage issues
Thankfully, our commercial plumbers caught these early—and were able to step in with effective, preventative solutions.
What Is Water Ingress, and Why Should Commercial Properties Worry?
During our inspection, we uncovered a common but serious issue: the soil level surrounding the building was higher than the concrete slab, essentially creating a dam against the structure during rain events. Water was pooling along the wall plus, during rain events the water soaked soil was seeping through the joint between the slab and the precast concrete.
Even more worrying? There was no waterproof membrane installed—an essential line of defence against water ingress in commercial buildings.
How We Solved It:
Our commercial plumbing team immediately:
- Lowered the external soil to below slab height to allow proper drainage.
- Recommended installing a waterproof membrane to prevent future seepage at the slab-to-wall junction.
Commercial Plumbing Pro Tip: Regularly check landscaping and soil levels around your building. Raised soil can trap water, leading to long-term structural damage and mould problems.
Flooded Carparks? Blame Blocked Stormwater Drains
Another major issue at the site: the carpark was flooding during heavy rain. Our investigation revealed blocked stormwater pits and drains—plus a major obstruction at the stormwater discharge point into the easement.
This is a classic example of how unchecked drainage systems can cause chaos, especially in commercial complexes.
What Our Commercial Plumbers Did:
- Cleared stormwater pits full of sediment and debris.
- Jet-blasted the stormwater lines using high-pressure equipment to restore flow.
- Removed the major blockage at the outlet point—eliminating the flood risk.
Commercial Plumbing Pro Tip: Stormwater systems should be inspected and cleaned every 6–12 months, especially at commercial sites with heavy foot traffic, tree coverage, or known drainage and stormwater drain system issues.
