Do retaining walls need expansion joints?
Solutions: Expansion joints are required in masonry walls. Typically these are at 6 m centres for concrete blockwork and 12 m centres for brickwork. Suitable materials must be used in expansion joints to allow adequate movement of the masonry.
What is the spacing of the expansion joints in retaining wall construction?
Expansion joints should be located at intervals up to 90 feet.
How close to a retaining wall can I build?
A retaining wall should be at least 3 feet away from your house foundation. This will promote better drainage and provide you with adequate space inside your property to do your maintenance and repairs. It will also expand the usable space within your home.
How thick is a retaining wall?
Base width = 1/2 to 1/3 of the height of the wall. Base thickness = 1/8 of the height of the wall but not less than 12 inches. Stem thickness = 6 inches + ¼ inch for each foot of wall height.
Where are expansion joints required?
Expansion joints occur through all parts of a structure to provide complete separation – through floors, walls, ceilings, and roofs (interior & exterior).
Why are expansion joints required in brick walls?
An expansion joint separates brick masonry into segments to prevent cracking caused by changes in temperature, moisture expansion, elastic deformation, settlement and creep.
How far apart should expansion joints be in concrete?
Usually, expansion joints should be no farther apart than 2 to 3 times (in feet) the total width of the concrete (in inches). So for a 4 inch thick concrete slab, expansion joints should be no more than 8 to 12 feet apart.
What is the maximum spacing of expansion joints?
Maximum spacing of expansion joints range from 25-27 m in jointed reinforced concrete slabs, and from 40 m (for slabs <230 mm thick) to 60 m (for slabs >230 mm thick) in unreinforced concrete.
Do retaining walls need footings?
A buried structural footing is usually required for larger retaining walls. To create this, a landscaper pours concrete below frost level (the depth to which the ground will freeze during the winter). Footings poured too shallow are prone to shifting and moving if moisture in the soil freezes and heaves.
