Everything you need to know about waterproofing your home
Every South African homeowner can avoid lots of problems by waterproofing their homes.
I Have 2 x adjoining room spaces with existing concrete slab roofing Approximately 90sqm in total. When i say slab i mean, this was not done to standard by the looks of it. When it rains it leaks and varies probably between 50 - mm thickness, butt brittle as it can be. Bought this house as is. Concrete is cracking and breaking off and pieces fall down. I would like to replace the concrete roofing with IBR sheeting. Need a new registered with Municipality drawing for the change and also would like to break through one wall which already has plinth supports in (this was a large window previously it seems). We will do the breakout and build with our own contractor.

Side laps at 75mm and end laps at mm sealed together by torch on fusion. Vertical and horizontal turns should be fused to the primed surfaces; angles; outlets fillets and flat edges. All as recommended by DERBIGUM (m2) 3)Two coats of co polymer or bituminous aluminium paint (m2)
We're purchasing a home in Westdene and a general home inspection revealed some defects in the roof. We'd like a specialist to inspect and advise on the extent of the defect (how critical it is), give options on fixes and estimate the cost of fixing it. This is quite urgent (we need this done by Wednesday next week).
Hello I've got the metal roof that still needs to be redone and I'm not sure what type of roof is inside the house it's a normal roof white but I think water somehow went into the roof now it's just sitting there and causing my lights not to work and there's a leak next to the light bulb holder. I just need a quotation to see more or less how much it would cost to repair it.
After 1-2 days of continuous rainfall in our area water has somehow penetrated one section of our tiled pitched roof on the eastern side of our house and dammed up in a pool about 1 square meter wide on the inside of the lounge ceiling below from where it has saturated the surrounding ceiling board and dripped through nail holes into the lounge.
Waterproofing to the balcony: Aluminum doors will be removed to the balcony Aluminum doors and frames will be wrapped in bubble wrap and stored in the garage for safekeeping until re-installation. All cement and waterproofing layers will be chopped up and removed off-site from the balcony. Rubble skip will be on-site and removed once it is filled. All existing waterproofing will be removed. mm Turn-ups will be chopped off in order to apply the waterproofing application onto the bricks. Existing outlets will be removed. New 63mm Flange outlets will be fitted to the parapet walls to allow water to discharge outside of the balcony. Screed-to-fall will be done to ensure water runs out of the outlets, and that there will be no water ponding in any areas. 50x75mm Angle will be fitted where the door will be fitted to prevent water from running back into the rooms. The waterproofing application will consist of the following: x2 Coats of Mapei-Lastic Mapei-tape to all turn-ups and corners and into the cavities. Mapei-net the flat surface x1 coat will be applied, followed by the Mapei-net and Mapei-tape being applied on top of the 1st coat. 2nd coat will be applied over all of the above-mentioned after 24 hours. Aluminum doors and frames will be re-fitted. Turn-ups and bands around the frames will be plastered to a smooth finish. Waterproofing application and plaster will be left for x3 days before the painting and tiling can commence. New tiles will be installed.
Front part of new house needs roof installed. I have some trusses left that was also used in back part of house that is already installed. Approximately m2 left to be done right away. I have all the tiles already. House is in Mooivallei Park Potch. I need a roofing carpenter to ensure the job is done right. Additional m2 roof will be needed on second level but not urgent right now.

We are in the process of purchasing a home and from the engineers inspection, it looks like we may need a roof replacement/repair as the clay tiles are old. The structure is still in tact. I'd like to get a quote to understand potential future costs in the next couple of years. I would prefer contact via email or whatsapp. Thanks!
Please I would like to have a quotation of a building that has a floor and ceiling that is damaged because of an air handling unit that is placed on top of timber floor. The ceiling below that floor is also affected. Please I would like to have the following in the quotation: 1. An investigation on the cause and extend of the water damage on the floor/ceiling. 2. On top of the timber floor there is a torch-on waterproof. What is the rate of the waterproof when it is removed and when it is replaced with new. Thank you. Kind regards,
