Uneven Precast Steps

I have a set of precast concrete steps (only 2 risers). Would like to add brick pavers to both treads to get closer to 8" rise on each. Is there a better way to bond these pavers to the precast besides mortar? Lot of changes in weather in Erie, Pa. and a lot of traffic on steps and I don't think mortar is the answer. Thanks for reading.

Uneven Precast Steps

Concrete or clay pavers?

Adding to the treads (and possibly the landing) could result in uneven risers which is a safety hazard and code violation. This could be red flag if and when you go to sell the house.

Are you trying to make up for a low initial placement or settlement?

Nothing has moved or settled. For whatever reason.....the first riser is about 6 inches, the second riser is about 8 inches and then a 10 inch step into the house. By adding roughly a paver heighth everything will be close to 8 inches. Just trying to figure the best way to bond the pavers to existing concrete pre cast steps.

I believe your precast steps have sunk into the ground a couple of inches, from your description of the riser measurements. The one coming from your house should be 8" as should the first step. The middle one is correct, as it has to be since it is precast. I believe I would check into having the steps raised and a new footing poured to level the whole thing out.

What apparently has happened is that after the steps were set they (previous owners) decided to blacktop the driveway thus the reason for the difference in the first riser. Still looking for best way to bond pavers to concrete. I don't think mortar is the best but I may have to go that route or possibly that and non-shrink grout.

Uneven Precast Steps

Because of the density and low absorption, precast concrete can be difficult to bond to unless you prepare it correctly.

1. Make sure the surface is very clean and does not have grease ot salt on it.

2. Before applying a bedding, paint the surface with a latex bond enhancer such a Acryl 60 or similiar.

3. The grout instrucrions may also recommend the use of latex.

4. Do use not a non-shriink grout that contains a metallic compound to offset shrinkage.

5. For best durability, seal the pavers and grout.

This would apply to both clay and concrete pavers. If you are using clay pavers, make sure they are suitable for durability in your climate and have a roughened surface for safety.

Good luck!!
