How to Repair Sinking Physical Steps

Concrete steps that accept begun to sink pose a problem when it comes to repair. The reason the steps are sinking is that the subgrade beneath the steps has eroded. This tin come from the influence of a loftier h2o table or from the subgrade non being properly prepared to withstand the weight of the steps.

The trouble is that most concrete steps counterbalance at to the lowest degree a ton, and y'all accept to get underneath the steps to brand repairs. It is a doable project, only one that requires the rental of a lifting automobile and extreme caution.

• Shovel
• Hammerdrill
• Tape measure (if needed)
• Pencil (if needed)
• Hammer
• 2x4 (12" long)
• (4) concrete bolt sleeves
• Rebar (#v, 2 anxiety long)
• (4) eye bolts (2-ton or larger)
• (4) shackles (two-ton or larger)
• (iv) wire rope lifting cables (1/4-inch minimum diameter)
• Lifting machine
• Pea gravel
• Fill dirt
• Compactor (or hand tamp)
• Ready mix concrete
• Trowel
• Concrete cap (if needed)

Tip

Remove the heart bolts and insert a small plastic concrete cap into the hole earlier skim coating the cap with concrete. This way, should y'all need to elevator your stairs over again (which in areas with a loftier water table may happen every bit the subgrade is eroded) you lot merely have to clean the skim glaze off the cap, remove the cap and the holes for your eye bolts are already in place.

Alert

Never work underneath a concrete stair that has been lifted out of place. Should anything go wrong with the rigging attaching it to the lifting auto--or should the machine shift--the stairs could autumn, causing y'all serious injury.

1. Dig out all around the concrete steps with a shovel. Yous will want to create a trench that is a minimum of 12 inches wide and as deep equally it takes to explose the bottom of the concrete steps.

2. Drill 4 holes into your concrete steps with a hammer drill. You volition desire to place two holes on each side of the steps. Imagine that the side of the concrete steps is divided into thirds; measure and mark where these points would be. On the 2 lines that divide the step into thirds, drill a hole halfway between the bottom of the stairs and the meridian of the step or landing.

3. Drive a concrete colt sleeve into each hole. Hold a short piece of 2x4 over the terminate of the sleeve and strike the forest, not the metal, with a hammer to bulldoze it in. If you strike the metal of the sleeve you could curve the ends of the sleeve and your bolt would not fit.

4. Screw your eye bolts into the holes you simply drilled. Stick a short piece of rebar through the heart of the bolt to form a handle and make it easier for you to screw the bolt clockwise into the pigsty.

5. Remove the bolts from your shackles past turning it counterclockwise until it comes free and pulling information technology from the shackle. Hang the "U" part of the shackle through the eye bolt. Do this on all 4 eye bolts.

6. Hold one end of i of your wire rope cables so the eyelet is against the eye of the commodities and pass the bolt of the shackle through the shackle so if y'all pull the cable forrard it is caught on the bolt of the shackle. Tighten the shackle commodities past turning it clockwise. Do this with all 4 cables.

7. Lower the rigging on your lifting machine so it is centered on the stairs and all four of your wire rope cables can exist connected to the rigging. Connect the cables. Slowly raise the rigging on your lifting machine (consult the operator'south manual for the right procedure) until your concrete stairs lift off the ground. Once the stairs take lifted, pull them out of the ground and swing them abroad from the area. Lower the stairs onto the ground so they are out of your way--and you out of theirs.

8. Remove the subgrade that was below the physical stairs by digging information technology out with a shovel. Dig downwardly an additional 10 inches below the one-time subgrade.

9. Shovel ten inches of pea gravel into the hole so the bottom is evenly filled. This volition provide drainage for your subgrade.

10. Add fill dirt to the hole and apply a compactor or hand tamp to compact information technology. You want to refill the hole so the new subgrade is at the level of where the bottom of the stairs will residual. When this is done, lower your stairs dorsum into place. Remove the wire ropes and then the shackles, unscrew and remove the eye bolts. Mix a small batch of cement and patch the eye commodities holes. Make full dorsum in the earth around the stairs.

• Screw your eye bolts into the holes you just drilled.
  
• Practice this on all four middle bolts.
  
• Hold one end of one of your wire rope cables so the eyelet is against the eye of the commodities and pass the commodities of the shackle through the shackle then if yous pull the cable frontward it is caught on the bolt of the shackle.
  
• Once the stairs have lifted, pull them out of the basis and swing them away from the area.
  
• Remove the subgrade that was beneath the concrete stairs by digging information technology out with a shovel.
