Waterproofing Basement - The Best Kept Secrets
Waterproofing basement walls can be done in a number of ways, mostly dealing with the inside and outside of the wall. The best time to make sure your basement is waterproof is during construction when a waterproof membrane can be applied to the outside of the foundation. Poor original work, the home settling, or hydrostatic pressure from changes in the water table around your home could result in leaks and seepage through your basement walls. Some work is required to do basement waterproofing. And important questions to ask before work starts is “is basement waterproofing worth the investment?” or “is there return on basement waterproofing?”
Any hairline cracks, holes, or other porous areas in them should be identified. Fill in large holes with mortar but smaller holes and cracks will be ok then apply a waterproof mix. A dovetail should be chiseled out when filling in larger holes to allow the mortar to properly take hold from the inside. Mortar is usually one part cement to two parts sand with enough water to make a stiff mix. Just to add in, it is also important to know your basement waterproofing products uk where ever you may be, in US or UK or other countries. Also, watch out for complaints about everdry basement waterproofing products, if any. Do your research.
Make sure there are no air holes or pockets and use an ordinary trowel when applying mortar. Using a stiff wire brush to get rid of loose particles is also a good idea before applying the mortar to help it adhere because if the wall is leaking considerably you may need to put in a drainage pipe to a sub pump to help drain the water. Depending on the nature of the water flow this may only be temporary or it could be permanent. In much the same way as you would repair the larger holes in the wall, tackle the leaking floor joints.
Help it adhere by chiselling out a dovetail joint and make sure to incline the patch slanting it from the floor to the wall to provide strength and drainage. After repairing the wall we are ready to apply the waterproof mixture. The mixture does not adhere to a dry wall, but will not set on a wet wall either so remove any paint and mist the wall before applying it. The manufacturer’s instructions should be read carefully since epoxy and latex waterproofing mixtures usually require you to add some water, but you could also use your own mix of plain cement and water which should have the consistency of cream when mixed to a slurry. The mixture should be applied at the bottom of the wall with a stiff brush and spread by moving up in a right to left direction.
Every crook and crevice should be filled in. Feather the edges until the entire area is covered and leave it to dry overnight or until the mixture is not flaky. After the wall has dried overnight wet it down thoroughly again and apply a second coat of the waterproofing mixture in the same manner as the first. If you use one coat instead of two you may have to start over again as this will not do the job. Use this information as a way for do it yourself basement waterproofing systems and you will find waterproofing basement walls is not as difficult as it first appeared. Better yet, you will finally have that dry basement you have been wanting for quite some time.
