Hypertufa Rocks Project
Making Hypertufa Boulders for a Waterfall
I received an email from Carole M. asking me:
Could hypertufa be used to create boulders to be used on a waterfall on a pool? We built one that needs help. Thanks!
Thank you for contacting me and if you are referring to using a hypertufa recipe (or even a concrete recipe) to make boulders for your waterfall … yes you certainly can use the appropriate recipe for this project.
I suggest you read over ALL the pages of hypertufa and concrete information I have on both my website and my blog pertaining to hypertufa and/or concrete projects. There are things you need to be very aware of if your finished project will be in contact with plants or pond fish.
**Let me caution you that whether it’s a ‘tufa or concrete rock you are making, the thing you really must do as a final step before you allow plants or fish to come into contact with water that is in constant contact with your rocks or boulders, is to leach the lime residue out of the rocks/boulders (or even a trough or planter for that matter) completely.
This important step cannot be over-emphasized as necessary to do! Read more about that here: Build a Hypertufa Garden Pond Waterfall.
In addition, I will make a shameless plug on my own behalf, and recommend you purchase my Hypertufa eBook, as there is more in-depth information there that will be helpful to you. You can find information about my eBook here: HypertufaBooks.com. The eBook will more than pay for itself after you’ve made your first boulder, for sure!
A hypertufa or concrete boulder project will be quite an undertainking for you, so I will advise strongly that you do a small “test” project, or couple of projects, using the recipe you decide upon. Get the hang of working with the recipe; the curing time, etc.
Here is a blog post you will find informative since you’re new to working with recipe mixtures containing Portland cement: The Number #1 Cause For Most Hypertufa and Concrete Recipe Failures.
Best of luck in tackling your hypertufa boulder project!
