I'm very pleased with selected waterproofing contractors who took care of my basement. The owner picked up the phone anytime I called and the crew was friendly and professional. The final price was as arranged in the quote - they sent the best quote of all 5 contractors. Overall - very good experience.

I found your website when searching for waterproofing contractors near me. And I'm very glad I did, though I was a bit skeptical at first. All quotes arrived as promised and all contractors also contacted me by phone. The waterproofing company that completed the job was very professional... there were some initial issues but it was resolved quickly.

First step before waterproofing an area is to clean the surface to remove dust, grease, rust, paint and any other material which may affect the adhesion of coatings. After cleaning the surfaces, verify the dectivity and if necessary fix it in order to avoid water stagnation. Lastly, prepare the surface (the preparation process will depend on the type of surface).
A properly installed waterproofing system should last you anytime between 10 and 15 years. On the contrary, a poorly installed waterproofing system can cause water leakages almost immediately after it meets water, avoid such waterproofing mistakes. Roof waterproofing can last longer, especially torch on waterproofing.
Depending on the extent of damage on your waterproofing membrane and the age of it, you can choose between simple patches or a complete replacement.

sqaure meters IBR Flat roof, starting to leak at parepit Require full waterproofing solution Ideally liquid rubber solution The roof has been waterproofed previously with torch-on waterproofing but that is not lasting so I would prefer someone who specialises in liquid rubber waterproofing solutions.
Please email me and introduce yourself properly so that I can know who I am dealing with. I need waterproofing of 2 x apartment blocks. I need to get quotes for the Body Corporate for the repainting and sealing of the situated at the corner of Guthrie and Cliff Streets, De Kelders, Gansbaai from properly registered professionals.
I removed the tiles from the floor of my balcony as I had water problems in my braairoom below the balcony. I then sloped the balcony floor away from building walls and made the water exit holes bigger with more slope. I now need waterproofing on the floor of balcony. Question: If I want to use the balcony, can I walk on your waterproofing ??
I would like a quote for waterproofing. The structure is a concrete roof, it has been treated many years before but now, during heavy rains, the water is seeping through again, especially by the steal beams and where the walls join. I need a rubber-like type proofing please, not just a type of a painting. I am not an expert on this, but that is the type of application I have in mind.
