You deserve a home that stays dry through every Highveld storm — and a team that treats your walls like their own.
We are Petrus Construction and Projects, and waterproofing is what we live and breathe. From rising damp to leaking roofs, we find the source and seal it properly.
Every job we take on across Lenasia carries the same promise: do it once, do it right, and leave your property protected for the long haul.
That creeping stain climbing your interior wall isn't a paint problem — it's moisture travelling through your brickwork. We cut it off at the source and restore your walls to bone-dry.
When the bucket comes out at the first sign of rain, the damage is already overhead. We seal roof joints, flashings and penetrations so the next storm passes quietly.
Flat outdoor surfaces take the worst beating from standing water. We lay membrane systems built to shrug off UV, pooling and foot traffic — year after year.
Behind every failing tile is a wet area begging for proper tanking. We waterproof showers, floors and splashbacks before the grout ever touches the wall.
We walk your property, trace the moisture to its true entry point, and show you exactly what's happening.
You get an honest, itemised quote — no vague estimates, no hidden add-ons once work begins.
We apply the right membrane system for your surface, built to take what the weather throws at it.
We don't pack up until you've seen the work, understood it, and are happy with a dry, clean finish.
Cheap waterproofing coats the stain. We find where water actually gets in — and make sure it can't come back.
Tell us what you're seeing. We'll come take a look and tell you honestly what it needs.
We reply during business hours, Monday to Friday.
Let's sort the leak before the next storm rolls in over Lenasia.
