MEET CHARLES

30 Years in Construction. Built on Experience.

After 30 years in the construction industry, Charles Meintjes knows that some of the biggest property problems start with something seemingly small — a leak, failed waterproofing or a repair that was never done properly in the first place.

Years of seeing the same waterproofing problems recur led Charles to specialise in finding better, longer-lasting solutions and ultimately to establish On-Top Roof Renewal Solutions together with Gené Meintjes.

His approach is simple: identify the cause, prepare the surface properly, use quality products and do the job the right way.

“We don’t provide cheap repairs. We provide lasting solutions.”

THE ON-TOP DIFFERENCE

WE DON’T WORK OVER FAILED SYSTEMS.

We fix the foundation of the problem first.

When an existing waterproofing system has failed, adding another layer over it isn’t the way we work.

Where required, we remove the failed system, prepare a clean base and rebuild the waterproofing system correctly — making sure every layer is properly prepared and applied.

Because a lasting waterproofing solution depends just as much on what happens underneath the final coating as what you can see when the job is finished.

IDENTIFY THE CAUSE

We inspect first to understand where the problem originates.

PREPARE IT PROPERLY

Failed systems are removed where necessary to create the correct base.

BUILD IT RIGHT

The appropriate products and complete specified system are applied correctly.
