Pour Concrete Over Stone Wall

Pouring concrete over the existing one.

Pour concrete over stone wall.

After the lath is installed on the wall mortar is mixed and scraped onto the metal lath with a trowel. It sure is ok to put concrete against stone foundation i guess u mean something like plaster and not new wall just make sure to add good quantity of concrete against stones so that it binds stones. Here s the catch if the existing surface is somewhat in a structurally sound shape and elevating its height to a few inches won t be a problem you can certainly freshen it up with a new layer of concrete. Remove the sheeting or blanket daily wet the.

Height vertical thickness of the concrete footing. Wet the concrete thoroughly and then cover it with the sheeting of your choice using bricks rocks or other heavy items to hold it in place. It does depend on what purpose the wall is performing. Sheets of lath installed higher up on the wall are centered above the lower sheets of lath so that the sheets are staggered like bricks on a wall.

Spread the new concrete over the surface filling the entire area within the form you created. It s best to pour the concrete footings thick when building mortared stone walls. The new wall thickness will depend upon how thick your stone wall is and how badly bowed the stone wall is. The edges of the lath are overlapped by approximately 1 inch.

Specifically you can make them at least 12 inches in height. Smooth the surface using a two by four or float then add texture as desired using tools or a broom. The soil should be graded or sloped so the excavation site s center is slightly. The concrete block wall takes the job of retaining while the stone is for looks only.

My last wall was basically twenty four inches thick but twelve inches thick is a minimum you should build. For example a retaining wall higher than 600mm usually needs engineering by a structural engineer which is easier to achieve with core filled concrete block on footings rather than just solid stone. The minimum thickness i pour new concrete over existing concrete. I feel like pouring new concrete that s two inches thick over old existing concrete that s solid and sound is plenty thick enough for most applications.

Pouring concrete over existing concrete sidewalk when pouring new mix over old concrete make the mixture stiffer than usual by adding less water. I don t like to pour new concrete any thinner than 2 inches thick when i pour over existing concrete.
