Masonry problems usually have to do with water. If water seeps through areas, especially on walls and other support systems, a great deal of issues start to manifest. In the home, water damage could lead to the formation of mold spores and that could end up being deadly. It’s for that reason that professionals should be called in to fix, or even build waterproofing at various stages of home ownership and building. Do not try to do it on your own without the help of an experienced masonry expert, as you’ll find that several problems could occur.

Preventing water from penetrating historic masonry is important. If allowed to penetrate, it subjects the masonry to the damaging effects of freeze / thaw cycles as well as the crystallization of expansive salts. Penetrating and breathable water repellents should be considered as a possible tool to prevent water penetration. However, if an inappropriate water repellent is applied, it can actually assist in trapping moisture in the wall instead of keeping it out.
If you’re looking for  split face block selaing, and want to ensure that you get the best work. You’ll want to understand a few simple steps towards getting the right type of protection with your brickwork.

Selecting a Masonry Waterproofing system – First and foremost, we will choose the type and application of the product that will serve as the barrier between water and your home, or interior of a building.

Flashing Installation – Wall flashing is important and could come in many forms. Flashing is often done in line with sheet metal professionals and is required at various points of masonry and the home’s walls or moisture could seep in.

Weeps – Weeps need to be in place in order for drainage to occur. Water barriers are set up with flashing, weeps are put into correct spacing so that water can easily drain out and pushed away from any walls constructed.
