Logo for specialist exposed aggregate concreting business

This is what WA Exposed Concreting was looking for in their logo design

this is a new business located in Perth, Western Australia. We use exposed aggregate concrete for driveways, swiming pool area's, patio' etc - mostly residential properties. This is a specialist upmarket finish.
The design for the logo will essentially be the name of the business. We are looking for a contemporary design using a dark grey with either green or blue and maybe black outline but am open to ideas and will consider any colour or design
The logo needs to transfer well to business cards, email signature, quotes and invoices as well as signage on motor vehicles.
