The Waterproof Man
Basement, Basements, Negative Tanking
Basements are another area that frightens many people. So much so that many are now built as ‘wet basements’ so that the builder does not have to guarantee a totally dry area.
We have successfully waterproofed many basements over the years and we use a variety of successful systems depending upon the available access.
Our standard system for basements with good access is a liquid applied modified polyurethane rubber which being fully adhered stops the issue of water tracking through creases and depressed mortar joints behind sheet membranes.
The bottom joint between brickwork and concrete is the most critical area so it is good practise to over -excavate the area so that rain and washing water (if required) can flow away from the area to be waterproofed and not redeposit on the footing. This tip will save so much time wasted cleaning and drying concrete footings and save get your project out of the ground much quicker, especially in the winter. This comes with the bonus that your drainage system can then be set below the footing where it should be.
Property Line basements can be waterproofed using swelling bentonite clay systems, preplacement of membranes prior to pouring concrete walls or our own waterproofing method for corefilled brick walls.
When considering your basement waterproofing, do not forget a quality drainage system for the quicker water can get away the less hydraulic loading will be on your basement walls. We recommend a log drain system such as ‘Megaflow’ possibly paired with a walldrain.
