When we put a verb after a preposition, we normally use an –ing form, not an infinitive.
To as a preposition
To can be an infinitive marker (e.g. to work, to laugh). It can also be a preposition. When to is a preposition, it is followed by either a noun or the –ing form of a verb, but not normally by the infinitive. Common expressions in which this happens are look forward to, object to, used to, prefer to, get round to, in addition to.
