In a mixing bowl, combine the heavy cream and simple syrup, whisking until well blended.
Add the lime juice to the mixture and stir until fully incorporated.
In a large pitcher, combine the cream mixture with the soda water, gently stirring to combine.
If using fresh strawberries, wash and slice them; if using frozen, allow them to thaw slightly.
Add the strawberries to the pitcher and stir gently to distribute them throughout the drink.
Serve the mixture over ice in glasses and enjoy.
