STAFF REPORT <br />TO:Mayor Keis and Members of City Council <br />FROM:Bill Dircks, Public Works Director <br />DATE:September 6, 2018 <br />RE:Joint Repair at Fire Barns Skate Park <br />The concrete slab for the skate park has longitudinal joints that have a wide enough gap to cause <br />problems for skateboarders. The cracks have been caulked in the past but the caulk hasn’t held up very <br />well with the use and weather changes. Staff contacted Sierra Exteriors to get a quote for placing an <br />epoxy mortar in the joints, which should be a more permanent solution than the caulk. The product is <br />placed in the joint and left high and then is ground down so it is flush with the concrete. The cost of <br />the work was quoted at $2200. Staff attempted to obtain a quote for the same type of work from a <br />couple of other contractors but it is specialty work and the other contractors did not show any interest. <br />For comparison sake, caulking the joints costs around $1200 so if the epoxy mortar is a permanent <br />solution there should be a quick payback for the extra up front cost. <br />Staff recommends approving the $2200 quote from Sierra Exteriors to fill in the joints with epoxy <br />mortar.
