We apply fresh parging coats and repair crumbling foundation surfaces. GTA Masonry serves homeowners in Stoney Creek, Hamilton, and nearby areas.
Parging is a thin layer of sand and cement spread over the outside of a foundation wall. It covers raw concrete blocks and seals the joints from water and soil contact. Think of it like a protective skin for your foundation. Over time, frost, moisture, and ground shifting cause the parging to crack or fall off. This means the block joints underneath are left open to rain and cold air. GTA Masonry scrapes away the failed material, fixes the cracks underneath, and applies a fresh parging coat. We serve homeowners in Stoney Creek, Old Town, Stoney Creek Mountain, Winona, and Fruitland. Our work adds lasting curb appeal and home value that buyers notice.
Not all parging jobs are done the same way. Here is what makes the work GTA Masonry does on your Stoney Creek foundation last longer than a standard patch job.
GTA Masonry handles all types of parging cement applications and foundation wall repairs. Here are the specific services we offer.
Here is exactly what happens at your property from the moment we arrive.
Parging is a thin coat of sand-cement mortar applied to the visible above-ground portion of a foundation wall. The Ontario Building Code requires that all exposed concrete block foundations above grade be covered and protected. Without it, water enters the block joints and freezes, which splits the blocks from the inside.
The most common cause is applying parging to a dry or painted block surface. The block pulls moisture out of the wet cement, which causes it to crack. Also, frozen ground pushes on the foundation, cracking the rigid parging layer. We fix this with proper surface prep and the right cement-to-sand ratio.
A properly applied parging coat on a well-prepped surface lasts 15 to 25 years. Walls in full sun or heavy rain exposure may need attention sooner. Applying a breathable masonry sealer after the parging cures adds several years to the lifespan.
Parging helps by sealing surface cracks and slowing down moisture from reaching the block joints. However, if your basement leaks from active groundwater pressure, parging alone will not fix it. You will also need basement waterproofing drainage to manage the water before it reaches the wall.
No. Parging repair and replacement are standard home maintenance tasks. The City of Hamilton does not require a building permit for this work. GTA Masonry can start your repair as soon as you give the go-ahead.
No. Parging cement does not bond to paint. The paint creates a smooth surface that the mortar cannot grip. We must remove the paint by sandblasting or attach a steel wire lath to the wall so the parge mix has something mechanical to hold onto.
A parge coat should be between 1/4 inch and 3/8 inch thick. If it is too thin, it cracks easily. If it is too thick, the weight pulls it away from the wall before it cures. We apply the right thickness based on the condition of your specific wall.
Parging is a visible cement skin that seals the block surface and protects against surface water. Waterproofing involves drainage boards, membranes, and weeping tile systems that manage water pressure from soil side of the wall. Most homeowners benefit from both working together.
Cracked or missing parging lets rain and frost into your block wall every season. Do not wait until the damage reaches your basement. Call GTA Masonry today. We will inspect your foundation and give you a clear, honest estimate.
