Everything you need to know about waterproofing your home
Every South African homeowner can avoid lots of problems by waterproofing their homes.
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.

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,
We’d like to request a quote for the following activities: - Scoping and changing water usage at an office building; - This would include, installation of taps, which use less water; - Reduce bucket load of toilets/placing a brick in them or having spring mechanisms installed for no continued flushing by accident; - Water efficiency at the car washing area? They already use a hose. - We would like to implement changes that do not have to change peoples behaviors, rather work around those behaviors. i.e. reduce water coming out of taps for example, instead of trying to police people. - The office block has two levels and a small house area and a security house, this would then include o 2x women’s bathrooms, o 2x men’s bathrooms, o A bathroom for the apartment, o Bathroom for the security hut. We'd need the work to reduce water consumption by at least 20% and need a quote to approve funding requirements. Please let me know if there is any additional information I could supply. The funding is a fund we are fetching for a greening of a building. Funds will be released, we just need to know how much.
The basement is humid and is smelling musty, the walls are flaking in one of the rooms. In winter, cold air seeps through into the ground floor because of the wooden flooring and the spacing between the floor boards. I want a cost effective, economical and durable solution like a fibre seal for walls and underflooring.
I have a flat concrete slab roof. I need to replace the current torch on as it is leaking when it rains heavily and causing damp through out the building. The roof portion that needs sealing is over sqm, but I don't know the exact number off hand. I will need to go there later or tomorrow and walk off the measurement. I would like this sooner rather than later, but am a little flexible. I attempted a short term fix as I wanted to build on the roof, but it looks like I will have to wait on that now and just repair the roof. See attached pictures.
Repairs of aged/damaged water proofing on small sections of the roof showing signs of water damage and cracks. Cleaning of existing waterproofing membranes on the rest of the roof and replacing damaged pieces with overcoat and torching. Application of 2x overcoat matching the existing colour of the house.
Hi I would like a square meter rate for a torch on waterproof. There is existing torch on which is 20 years old, on a flat concrete roof. the square meters is sq/m. I would like a price first so we can see if we can afford it. It's a concrete roof . I am not there this next week, and we working on repairs on our house ,so we can extend our bond. Just need a more or less price. Then when I am back you can come to give me a accurate quote and help with the service.
I recently installed a jojo tank where the builder placed the pipes underneath a concrete slab but the conrete ended up in the pipes thus blocking it. I would like to relay a small portion of the pipe which directly comes out of the jojo tank and also lift the pump by 30cm. We will have to use a angle grinder to get the pump out.
We have a rumbling sound from what we think is air in water pipes in the ceiling that occurs regularly. This has been an ongoing problem for approximately two months. We have had four plumber call outs (two plumbers). Bathroom tap washers and toilet rubbers have been replaced. Pipes in the roof have been secured. Finally, a ' Hammer Arrestor to the Cold Tap' has been installed. All to no effect. There doesn’t seem to be a solution. The rumbling even sometimes occurs in the middle of the night. Our geyser is on the front wall of the garage. About two months ago we had the geyser moved to a side wall in the garage as we were advised that it was to close to the electricity board and an inverter we had installed. I am not sure whether this could be the problem.
