Concrete Roof Waterproofing

Concrete roofs are usually flat and have a notorious reputation for leaking. The fact is that these roofs will leak if not waterproofed effectively, early on in construction. This also allows for internal finishes to be undertaken.

Inverted Roofs for Concrete Slabs Waterproofing

The National Building Regulations and Building Standards Act requires all roofs to be constructed safely and in such a way that they cannot be damaged by wind or water.

Low Pitched Roof Waterproofing

A roof that is nearly level or slightly pitched is called a low slope or low pitched roof. No roof should be dead level flat; it must have at least a slight slope to drain.

Inverted Roofs Waterproofing

Our professionally tested process for installing on inverted roofs ensures the Multi-dex system is as effective as possible for your home.

Here’s What Our Client Say about Us

“The new low pitched roof waterproofing you installed over our babies’ nursery has bought peace of mind to all of us here at TLC. Not having to worry about a leaky roof every time we have rain is such a great relief! Thank you Multi-Dex!”

Pippa Jarvis

MD, The Love of Christ Children’s Home

My house has a roof construction which is extremely prone to leaking. It used to be a nightmare until I began my long road with Multidex about 15 years ago. Since they sealed my roof and aided with some structural changes, my nightmares have disappeared. They maintain their work every 3 years, which is worth every cent because they have gone beyond the 10 years of their original guarantee, still honouring their workmanship and material, still responding to each little problem which may arise.

Dr Eras van der Walt

Our complex have been dealing with Multidex for the past 10 years for all our water proofing requirements. Multidex is a highly professional company with professional and friendly staff. I can recommend Multidex for all water proofing requirements.

Christine

I have had the waterproofing system installed by Multidex for approximately seven years, and I am extremely satisfied with both the product and the service provided. Since installation, the system has made a significant difference to the internal temperature of my property, keeping it noticeably cooler in summer and warmer in winter. Most importantly, it has successfully prevented leaks and has performed exactly as promised. The workmanship was very neat and professional. The company also carries out maintenance every four years, which gives me continued confidence in the long-term performance of the system. Overall, I am very happy with the results and would confidently recommend Multidex to future clients.
