Last fall I noticed some small cracks around the handrails from the exit in our deep end (Recessed steps in side of pool wall). I filled with Sika flexible concrete sealant. Over winter the cracks have widened quite a lot, caused the aluminum cove to bow out approximately 3/8” over a span of around 7-8’. The cove is the top of the rail holding the automatic pool cover. What is the best option for repair as the sealant clearly didn’t work? It is hard to find pool repair people in my area (central Ohio).
