Sheer Descent Help

[Noli]

Had a company come out to replace my sheer descent due to a cracked joint. Unfortunately, they do not do masonry. Can someone help with providing info on the proper method for performing this repair/rebuild so that I know I've found the right person/company?

• What material(s) should be used (mortar, concrete, other?) and where?
• What should be in between the top of the sheer descent and the flagstone that will sit on top of it.
• Any other tips, etc??

I've attached a few pictures to help describe my situation.

Thanks!

Love the dog statue on the top.

Hydraulic cement to fill in the holes and Type S mortar to secure the stones.

What model sheer descent was installed?

Thanks for the quick reply!! I'm not sure which model it is.
So hydraulic cement to fill in around the pipes. Then after it cures, use Type S mortar to secure the bluestone. Should mortar be used in between the sheer descent and the bluestone?

Yes - that dog statue always ends up positioning itself wherever I'm working in the yard!!

I would like to see what the sheer installation manual says about mortar and stone on top of it or if you should put a stainless steel plate over it.

@AQUA~HOLICS may have thoughts.

I'll see if I can find out which model was used - but I doubt I will get that info. Unfortunately, I don't see any markings on the sheer descent except for a few labels that DO NOT have the mfg's info nor model number. UGH!!!

As stated above for types of products to use, a crack will appear at the point where the two products meet due to they will not adhere/bond together so separation will occur.

Is there something that you recommend that will prevent cracking? If a thin stainless steel plate - as mentioned above - is placed on top of the sheer descent, would that do the trick?

Why is there any doubt?

Ask for the installation manual that came with the sheer descent.

Is there any reason that they will not give it to you?

It’s two different types of material that will contract and expand differently so you will have cracking.

I have had trouble getting in contact with the company who installed the sheer descent - but did find the model info. It's a CMP Natural Wonders 25577-430-900.

See the attached manual. It shows the coping bridging over the waterfall and being anchored to the bond beam around the plastic.
