I have a plot in the Stockholm archipelago and have just laid blasting stone against the rock at the shoreline and then placed blasting stones above with a slope of maybe 1:2 to a height of 1.8 meters. The stones at the bottom probably weigh 0.5 to 2 tons along the entire shoreline. All are on rock that is 0.2 to 0.5 meters below the water surface. Some stones are placed "optimally" with a rock ridge as support, i.e., in a local "hole" in the rock. Others are on flat rock or even rock that slopes slightly outward. I think these might be pulled away by the ice in winter since there are several square kilometers of open water outside.
I have plans to cast the blasting stones together by first "reinforcing them" with 16 mm rebar and then casting. I would also like to cast concrete ledges on the rock at the slightly sloping rock as a counter for the blasting stones. These ledges must, of course, be reinforced and doweled.
Two questions:
1) When I dowel my 16 mm rebar into the rock, should I use anchor cement (or anchor compound) in the drill holes or is it enough to drive in the rebar and then let the concrete provide corrosion protection?
2) Does anyone know of a suitable anchor compound? There are many on the market (e.g., Sika AnchorFix-1 Quick-Setting Anchor Adhesive) but I don't want to take any chances.
Do you think my approach as per above will work or do you have any other ideas? Grateful for answers.
Best regards,
/Björn
