2728. The hypothec secures the increase in value given to the immovable by the work, materials or services supplied or prepared for the work. However, where those in favour of whom it exists did not themselves enter into a contract with the owner, the hypothec is limited to the work, materials or services supplied after written notice of the contract to the owner. A workman is not bound to give notice of his contract.
