Subject: Re: Construction Gurus... question... by teebee on 2011/8/19 13:07:27 My first thought was the use of the cordless hammer drill....an electric drill with a GOOD bit is a must. And the age of the concrete is a factor too. slabs around here are typically 6 bag mixes and as said earlier, as concrete ages it gets harder. Concrete doesn't reach it's full strength until it's 60 years old. I'd try a corded hammer drill. |
